@smawis I run my own network so the SIM is just off the shelf. It is an OpenBTS system that I demonstrate in the next episode. (episode 4) The GSM modules act as mobile stations, yes. they function very similarly to standard cellphones (like the smartphone in the video) but don't have audio hardware set up. You could easily wire in a microphone / speaker though. These modules are really made for data applications like data collection or command and control. Thanks for watching.
In this case I'm just calling amongst devices on my own private network. However, an Internet connection and a SIP trunk service can supply connectivity to the public switched telephone network so you can call any phone in the world. As it happens, I have that as well but that's a bit off topic and I didn't want to confuse the issue.
@engtarkan Just turning the radio on with a valid SIM in it will cause it to associate with a network. You will get a notification when it associates. (as it does in the video) When an SMS arrives, (also demonstrated in the video) it gets stored on the SIM card. I also demonstrate how to read the message off of the SIM card and display it's text so you would have to use similar commands. Lastly you will want to delete the message from the SIM so it doesn't fill up and start refusing messages.
@Neolith100 I work for a telecommunications company so I have several hundred SIMs but you can use valid SIMs as well as long as you tell the phone to connect to your network. For the phone numbers, you can just make them up and program them in. Real numbers only matter if you connect Asterisk to the phone network which I have done but not in these videos. I find it most helpful to use believable test data. Thanks for watching.
Not really - generally this module is considered a "black box" and communication is handled through "AT" commands via a serial interface. While possible, there isn't generally a need to get below that. See the docs available on SparkFun's site.
I did it before reading this comment and it wasn't complicated at all. After figuring out how to get minicom and finding the usb dongle in the /dev directory everything was fine. i was actually surprised I usually straggle with these things and really have to bang my head against the problem.
Yes, the setup in this video does require an external computer. (although the E100 in another of my videos wouldn't: youtube. com/watch?v=g3-SjnES0K8 ) The 100mw Tx I am using would go several city blocks if I were outside though I'm deep in the bowels of a building where little radio signal can leak. You can use an amp with this rig but you probably want to split the transmit / receive paths as well. I haven't done that though so I don't have much in the way of suggestions.
Yes it's possible to send call audio through the sound card although you would be restricted to one call at a time. (for hopefully obvious reasons) And yes, you can sense DTMF key presses. But you probably want to look at Asterisk or FreeSWITCH to do both of these.
Engtarkan: you don't need the development board but it makes it far easier to get at and test the GSM module. If you didn't use it, you'd need some way to power / read data off of it. The critical component is the surface mounted header. Yes it is possible to do what you are asking. I'd use the development board to do this if I were you.
They are 30 inch Apple Cinema displays. 2 are on rotatable arms in a vertical orientation which I find much better for coding / reading long web pages. The other is landscape which fits 16:9 video better. I picked the idea up while working at Google in Seattle.
ooh thank you sir, i will order the part today, you helped me alot thanks sir.. and i love these types of upload.. dont stop and good luck .. thanks again anders94
@digitwolfcom Are you sure the USB serial port shows up in the operating systems you are trying? Make sure you are picking the correct port. I forget the baud rate (9600/ 57600?) but 8 bits, no hardware flow control and 1 stop bit should be the other settings.
Even on your own network you're running Asterisk and SIP, in order for the board to be able to call the Nexus phone, right? What kind of range can one get with the 100mw TX daughter-board in the N210? Is there a power amp you would recommend to extend the range? Thanks.
The SIM will store 10 - after that the oldest will be deleted. Usually you "grab" the messages as they come in and don't depend on the SIM's limited memory for them.
3.8 volts is probably better than 12 volts for a mobile context so it is a good choice. Usually hardware accepts a range of voltages. Check your docs on that. I'd guess 3.8 is a maximum and 3.3 (which is very common) is possible. Also, the number of volts isn't the only thing that contributes to how much power is actually flowing through a project. The number of amps and volts together matter more. :)
Mac (version 10.7.5) I have not gotten the ADH8066 to ever work. I’m trying to connect via USB to just prove I can get it working and build from there. The adrino, I use, I connect via usb and works great for other things. I connect the ADH8066 via USB and get a flash on transmit receive, then press on key until the status light comes on.. just can not get to the point of seeing it to send it commands. Thanks for taking time to respond!
oh yess - working perfectly :) I'm using GOSERIAL on MacBook Pro. Settings are: Serial port: usbserial-a9014fsxxxx speed:115200 bps Data bits:8 Parity: none stop bits: 1 Hardware Flow Control Input: RTS Output: CTS Local Echo: Off " at OK "
@tmid84 Technically this was my SIM on my own private GSM network but I did test this on public networks - AT&T and T-Mobile in the U.S. As far as I know Verizon doesn't operate a GSM network - they are CDMA so this wouldn't work with them.
I'm confused.. I just caught this on ur 3rd video.. I see ur operating ur own network? but to make a call wouldn't you need to go thru a switch to get out in the public telephone network? and same with data and sms? or is it just calling between that little network u made?
I connected it to a window device and now able to communicate with it.. Small steps. Thanks for the help! have you heard of any issues using a sim card from at&t go phone the white and orange one. I can not get it to connect to a network and looks like it continues to restart
Also: Suppose we want to store those messages on the computer, then delete the message from the SIM card and do it again for the next incoming SMS.. Any idea on the cycle duration ? Minimum time to do all that and be "ready" for the next one ? Any documentation you might recommend, etc...
I am thinking to buy the SM5100B Evaluation Board but it says it's on 3.8 volts no more 12.. why 3.8 instead of 12? is it a US new regulation thing? will 3.8 volts be enough? Where am I supposed to find a 3.8 power adapter in the uk?
I have the ADH8066 and evaluation board like in your video. When connected to usb I do not see the device (ls /dev/tty.*) when I connect my arduino UNO, I can see the device.The SIM card is an AT&T and tested and works in a phone. Any suggestions to trouble shooting or good resources to get me going it the right direction with the ADH8066?
From the docs on the SparkFun site, it looks like 5 volts is too much. I'd feed it 3.6 volts. (hopefully it isn't burned out but the docs say "power supply can never be greater than 4.5 V) Also check the flow control in your terminal program - looks like the UARTS on that have hardware flow control.
I am using the sm5100b module and eval board (similar to yours). I am having the issue of nothing at all showing up on the terminal. I'ave tried baud rates of 9600and 115200. I'm feeding it 5V as indicated on the board everything is connected and new out of the box. Do you have an suggestions on what i could be doing wrong?
@digitwolfcom After making sure the serial settings are correct and pressing the reset button, it usually comes up with some data. If not, I hit enter a few times. Try other serial software or another system if you suspect serial misconfiguration. I'm using Linux / minicom in the demo.
@wookster77 The way SMS works, a tower must be involved. SMS messages can't go directly from one handset to another. In this case, I do go to a tower, but I happen to run that tower. See the video I did on OpenBTS - that is the "tower" I'm actually using in this video.
Thank you for your quick response. I actually solved my problem, the issue was one that it needed more power and two i needed to select the proper frequency for my region. If you dont mind, as another question, have you ever ran into the issue that you actually had to poll the SIM for received messages? When mine is sent a message, it doesn't alert me like yours does.
How do i programme the gsm module to send the apropiate data by sms to my phone whenever it recieves anything? do you need a certain software? Thanks for helping me out
Hello, i wanna do a voip forwader, so, i gotta couple questions for you, if you dont mind in help me. 1st one, is it possible to talk through the computer audio card? 2nd, when in ca call, is it possible to know from the computer that the the other phone has pressed the 2 or the 3 key?
thanks,yes it works with serial communication, my application is to use the microprocessor as a switch. when a sms is sent to the GSM modem, i want the GSM to send a serial signal to the 8051 so that the 8051 set other pins high or low, so my problem is how to start the GSM modem and how to set it to receive SMS messages from a cell phone and then send a serial signal .. thanks again fro the help
hi anders, i have order all the parts and now i'm ready to work with, i'm asking how can i start on programming this module using a 8051 micro-controller ? can you please upload a full tutorial for setting up from scratch how to operat it and when a SMS is sent to it it sends a signal to the 8051 .. sorry , but really i need some help
Can I Implement GPRS data services through Open BTS and USRP. Also it is possible or not to call on other networks through our own BTS system like openbts?
So looked over the posts and saw that you were using OpenBTS and used an "off the shelf" sim... where did you get that? lol, didn't even know those existed. Secondly, how did you get Asterisk to assign an almost "valid" looking phone number... is that some coding trickery? :-) BTW, seriously enjoyed this and your other vids... good, clean to the point info, love it!
if i'm understand correctly to this tutorial. you try to make a new phone by using GSM module and communicate to another phone right. it look like new phone lol. love it.
its a small mini device that reads any card data like gift cards etc i need it for a project that me and my friend are doing, instead of him sendng the data wih all those numbers he could easily swipe the card on the msr and the data is sent to me on phone (using the gsm module without being plugged in a pc or anything). so how do you correct the gsm module to only sending it to MY phone by sms whenever it recieves any data?
I'm not sure I follow you on the 2 phone bills but practically, yes, you would want an activated SIM. As it happens, the ones in this demo aren't though because I am running my own GSM base station. Search for my video on OpenBTS to see that.
so basically if you send a char* "at+cmgf-1" via a serial port then wait for "OK" and then you send the bytes "at+cmgs=999422422" delay 1 sec and then just send a char* "message" and it will send it?
Good Job. I've tried this with Breakoutboard but couldn't start it up. Will test with Eval board - CEL-10741 now and post if succeed. I need this for arduino project so still wonder what other (if any) can be smaller than this.
There is a good chance your terminal settings aren't what the device is expecting. I'd have guessed your USB serial driver but you say the Arduino works. I do most of my development on a mac through the same terminal emulator as the Arduino (actually I use the maple variant) but it should work. I'd just check terminal settings - 9600baud, 8, No and 1, etc.
hello sir, i need your help please, is this device has to come with the development board ? or there is no need for it ? and i would like to ask, if i want to read a Text message and then send a signal to a microprocessors is it possible? please help
Have ADH8066+ Eval Board + Activated TMobile with minutes. Followed your video exactly and received the IIII......... Ready. I type at and get the OK. I press and hold the ONKEY but do not get the +CREG: 5 response. I type at+cpin? and get CPIN: READY OK. I type at+csq and get +CSQ: 7,99. I type atd727....... and get NO CARRIER response. Where should I look next?
Very Nice video , Great module :) , Can the logic pins such as the TX/RX on the module handle 3.3V logic levels without any damage/issues such as on a 3.3V arduino ?
Theoretically yes, but no. It would be unbelievably complicated. You would have to reverse engineer the hardware and replace the firmware without documentation.
Amazing how you can mold technology nowadays...hey Andres i want to make an IMSI Catcher ...low cost imsi catcher just as a mini project...can you guide me on how i can start working on it..And thankyou for this great content..Stay blessed :)
LOL he didnt answer u, i wonder y......yeh Anders just help me out with an IMSI Catcher oh and make it lowest cost possible pls --> Anders is like YES mate whatever u need u just let me know champ, oh and of course happy hacking 2u!
I have no idea, but these things act very similarly so I wouldn't be surprised if you found they worked just as I demonstrate here. In fact, if you dig into the internals of Android, you'll notice it talks to the cellular radio subsystem in an eerily similar way. ;)
It depends on the device. In this case, no. The ADH8066 will actually return an error when it senses USSD data but I'm sure you could find a device that support it.
A prompt reply like this does not deserve the punishment of a follow up question, but .... Probably I will go for some USB dongle and have a go, are the commands universal? could you point me to a reference. thanks again
Mac Gate AT command interfaces aren't completely universal but you shouldn't feel like you are in much of a foreign land using it with just about any other chipsets. Other chipsets may, however, also have a binary driver option which would work very differently. (and likely what would be ideal for USSD) The best reference is going to be the data sheet for the hardware you end up with. For something general though, the "getting started" guide on SparkFun's page on the ADH8066 isn't bad.
does anybody know of any software that can be used with this thing that would allow you to do some kind of SMS/MMS gateway, maybe interfacing with an SQL database? I can hack all that kind of stuff, but i'm not really a coder at the level of writing drivers for this.. thanks!
Hi there, very good video. Although, I have a question. Imagine I make a phone call to the board. The mic (if attached to the board) starts to get analog signal and then the sound signal will be digitized and processed a bit before reaching the GSM module to be sent over the network. Now, what if I want to do a custom processing on the digitized signal before it heads over to the GSM module. Do you have any idea how I might be able to do that? Kindest Regards
You couldn't do that with this module because the analog mic input goes into the chip where the analog to digital converter is so you don't have the digital data outside the chip. Presumably, if you found a chip that takes digital audio input, you could do your own analog to digital conversion and then do some alteration of the digital data. I'd caution though that the digital data you send in will not be the digital data that comes out the other side. There is loss of data because the GSM codec heavily constrains the frequency range and other aspects of the audio signal.
Anders Brownworth thanks for your reply. I'm aware of the constraint the gsm network impose on the signal and and also the heavy vocoder operation. Yet I need to do some sort of byte xoring with the digitized samples of the audio before sending it over the network. Since the signal I'm xoring with the original data is a sequence geberated by an unpredictable PRG, the resulting signal is somewhat a uniform noise with frequency spectrum spread all over the band. Therefore I think the gsm error correction schemes are enough to cope with lossy data. Nonetheless, I still am struggling to find a way to manipulate data before it hits the GSM module because as far as my knowledge extends, there is no way to get into dsp unit (baseband processor) of the gsm module and there is also no way send digital data to the gsm module from the main board (say stm32 something). So if you know a way or possibly have some documentation that I could use I would highly appreciate it if you could send them to me or at least reference them. If its not too much trouble though :) Thanks alot
I'd suggest you look into an SDR setup like the Ettus Research USRP devices and try running OpenBTS. You'll be able to get in to the post DAC audio but before it goes to the GSM blocks. I did a video on OpenBTC and this hardware here: th-cam.com/video/pTb1_v8M6iA/w-d-xo.html
I have never heard of a carrier whitelisting an IMEI - usually they only blacklist them. I was speculating that they could choose to whitelist if they wanted but it seems like more trouble than it is worth.
I think he was waiting for you to show how to "hack" girls' Facebook profiles and read messages. He must have been disappointed. But be assured that the audience that matters *ahem ahem* is delighted by this, so thanks Anders. Can I download your brain for a bit: How many SMS sent to that can the module (or the SIM, inherently) keep up with. Maybe causing a DoS or something ? i.e: How many before it starts to go nuts ?
Thanks for the suggestion. The connection between the GSM module and whatever else you want to use (arduino in this case) is just a serial port so a slightly modified "serial hello world" script should be able to drive the GSM module. I don't happen to have an arduino handy for this though. Have one you want to send me?
In the typical case, yes you do have to pay for the calls if you have a SIM from a public network. In my case, I am running my own private BTS so I don't have to pay. (see my video on that on youtube at: pTb1_v8M6iA)
@smawis I run my own network so the SIM is just off the shelf. It is an OpenBTS system that I demonstrate in the next episode. (episode 4)

Yes, absolutely. I'd suggest you use a serial library though to make it easier on yourself.
Yes, the setup in this video does require an external computer. (although the E100 in another of my videos wouldn't: youtube. com/watch?v=g3-SjnES0K8 ) The 100mw Tx I am using would go several city blocks if I were outside though I'm deep in the bowels of a building where little radio signal can leak. You can use an amp with this rig but you probably want to split the transmit / receive paths as well. I haven't done that though so I don't have much in the way of suggestions.
please make more videos about cybersecurity for beginners , your videos are useful
I'm not familiar with the 8051 platform but as long as you have serial I/O working I would think you could do an interface. What's your application?
Depends on the module - some of these commands are fairly proprietary but the idea is the same. Take a look at the docs.
Yes it's possible to send call audio through the sound card although you would be restricted to one call at a time. (for hopefully obvious reasons) And yes, you can sense DTMF key presses. But you probably want to look at Asterisk or FreeSWITCH to do both of these.

Where did you get this modules? Can you make any controls with GSM messages, but what more possiblities have?

No worries - best of luck!
What? The johann Sebastian Bach of the electronics. LOL
Yes, you would need something programmable to drive it such as an Arduino or Raspberry Pi.
I have a question. Is the modem sending an sms directly to the phone or via a GSM tower? Sorry for the noob question, still learning.
The SIM will store 10 - after that the oldest will be deleted. Usually you "grab" the messages as they come in and don't depend on the SIM's limited memory for them.
Yes, you can do GPRS with this although I don't demonstrate it. GPRS is part of GSM as of Release 97.

Generally GSM radios and SIMs aren't used with FreePBX. That's somewhat of a different topic.
No, I have never had to poll - I've always gotten the notification. That's odd that yours doesn't.
@tmid84 Technically this was my SIM on my own private GSM network but I did test this on public networks - AT&T and T-Mobile in the U.S. As far as I know Verizon doesn't operate a GSM network - they are CDMA so this wouldn't work with them.

@whyteks smsqueue which is included in the distribution can easily be modified to use a database.
What SIm card did you use? Do you know what networks this device is compatable with (Verizon, AT&T, etc.)?
I connected it to a window device and now able to communicate with it.. Small steps. Thanks for the help!
have you heard of any issues using a sim card from at&t go phone the white and orange one. I can not get it to connect to a network and looks like it continues to restart

so basically if you send a char* "at+cmgf-1" via a serial port then wait for "OK" and then you send the bytes "at+cmgs=999422422" delay 1 sec and then just send a char* "message" and it will send it?
.. unfortunately the board is out of stock though.. do you know any alternatives??
Which model microcontroller is suitable for this?
Good Job. I've tried this with Breakoutboard but couldn't start it up. Will test with Eval board - CEL-10741 now and post if succeed. I need this for arduino project so still wonder what other (if any) can be smaller than this.
There is a good chance your terminal settings aren't what the device is expecting. I'd have guessed your USB serial driver but you say the Arduino works. I do most of my development on a mac through the same terminal emulator as the Arduino (actually I use the maple variant) but it should work. I'd just check terminal settings - 9600baud, 8, No and 1, etc.
hello sir, i need your help please, is this device has to come with the development board ? or there is no need for it ?
and i would like to ask, if i want to read a Text message and then send a signal to a microprocessors is it possible? please help
Hey
There are many 3G Modules from Notebook available does this Code worke to?
THX!
Great Tutorial Andres
Thanks ;)
Have ADH8066+ Eval Board + Activated TMobile with minutes. Followed your video exactly and received the IIII......... Ready. I type at and get the OK. I press and hold the ONKEY but do not get the +CREG: 5 response. I type at+cpin? and get CPIN: READY OK. I type at+csq and get +CSQ: 7,99. I type atd727....... and get NO CARRIER response. Where should I look next?
I used minicom to communicate with it though you could use any terminal emulator.
wish it wasnt so expensive :o
looks fun
Just about any Linux distribution will work. Personally I used Gentoo for this but have been using Ubuntu lately.
Yes.
Yep, it should.
By any chance are you familiar with snmp? I am having a very hard time with it and I am desperately looking for help.
Very Nice video , Great module :) ,
Can the logic pins such as the TX/RX on the module handle 3.3V logic levels without any damage/issues such as on a 3.3V arduino ?
can i use any SIM with freePBX if yes what is device for it plz let me know about low price device for one sim ony
Could you have a controller reset the board and send the AT commands for you? Have you tried this before?
privacy has died
Theoretically yes, but no. It would be unbelievably complicated. You would have to reverse engineer the hardware and replace the firmware without documentation.
so basically in order to have something like this you would have 2 phone bills, i assume the SIM card must be active correct?
Did anyone try to call the number?
Hi Anders!
what linus configuration I need to do this cennarius?
Thanks in advance.
lovely.
Amazing how you can mold technology nowadays...hey Andres i want to make an IMSI Catcher ...low cost imsi catcher just as a mini project...can you guide me on how i can start working on it..And thankyou for this great content..Stay blessed :)
LOL he didnt answer u, i wonder y......yeh Anders just help me out with an IMSI Catcher oh and make it lowest cost possible pls --> Anders is like YES mate whatever u need u just let me know champ, oh and of course happy hacking 2u!
Do you know if this is similar to the module on the arduino shield from seeedstudio?
I have no idea, but these things act very similarly so I wouldn't be surprised if you found they worked just as I demonstrate here. In fact, if you dig into the internals of Android, you'll notice it talks to the cellular radio subsystem in an eerily similar way. ;)

Great tutorial,
Will the interface be able to send USSD commands and read the network replies?
thanks
It depends on the device. In this case, no. The ADH8066 will actually return an error when it senses USSD data but I'm sure you could find a device that support it.
A prompt reply like this does not deserve the punishment of a follow up question, but .... Probably I will go for some USB dongle and have a go, are the commands universal? could you point me to a reference.
thanks again
Mac Gate AT command interfaces aren't completely universal but you shouldn't feel like you are in much of a foreign land using it with just about any other chipsets. Other chipsets may, however, also have a binary driver option which would work very differently. (and likely what would be ideal for USSD)
The best reference is going to be the data sheet for the hardware you end up with. For something general though, the "getting started" guide on SparkFun's page on the ADH8066 isn't bad.
nice
Do you think I can use this inside a c++ program?
@anders94 thank you Mr anders ..
does anybody know of any software that can be used with this thing that would allow you to do some kind of SMS/MMS gateway, maybe interfacing with an SQL database? I can hack all that kind of stuff, but i'm not really a coder at the level of writing drivers for this.. thanks!
Hi there, very good video.
Although, I have a question. Imagine I make a phone call to the board. The mic (if attached to the board) starts to get analog signal and then the sound signal will be digitized and processed a bit before reaching the GSM module to be sent over the network. Now, what if I want to do a custom processing on the digitized signal before it heads over to the GSM module. Do you have any idea how I might be able to do that?
Kindest Regards
You couldn't do that with this module because the analog mic input goes into the chip where the analog to digital converter is so you don't have the digital data outside the chip. Presumably, if you found a chip that takes digital audio input, you could do your own analog to digital conversion and then do some alteration of the digital data. I'd caution though that the digital data you send in will not be the digital data that comes out the other side. There is loss of data because the GSM codec heavily constrains the frequency range and other aspects of the audio signal.
Anders Brownworth thanks for your reply.
I'm aware of the constraint the gsm network impose on the signal and and also the heavy vocoder operation. Yet I need to do some sort of byte xoring with the digitized samples of the audio before sending it over the network. Since the signal I'm xoring with the original data is a sequence geberated by an unpredictable PRG, the resulting signal is somewhat a uniform noise with frequency spectrum spread all over the band. Therefore I think the gsm error correction schemes are enough to cope with lossy data. Nonetheless, I still am struggling to find a way to manipulate data before it hits the GSM module because as far as my knowledge extends, there is no way to get into dsp unit (baseband processor) of the gsm module and there is also no way send digital data to the gsm module from the main board (say stm32 something). So if you know a way or possibly have some documentation that I could use I would highly appreciate it if you could send them to me or at least reference them. If its not too much trouble though :)
Thanks alot
I'd suggest you look into an SDR setup like the Ettus Research USRP devices and try running OpenBTS. You'll be able to get in to the post DAC audio but before it goes to the GSM blocks. I did a video on OpenBTC and this hardware here: th-cam.com/video/pTb1_v8M6iA/w-d-xo.html
Anders Brownworth thanks alot man i really appreciate it
How does the IMEI work with whitelisting a device to a SIM?
I have never heard of a carrier whitelisting an IMEI - usually they only blacklist them. I was speculating that they could choose to whitelist if they wanted but it seems like more trouble than it is worth.
I think he was waiting for you to show how to "hack" girls' Facebook profiles and read messages. He must have been disappointed.
But be assured that the audience that matters *ahem ahem* is delighted by this, so thanks Anders.
Can I download your brain for a bit: How many SMS sent to that can the module (or the SIM, inherently) keep up with. Maybe causing a DoS or something ? i.e: How many before it starts to go nuts ?
hi, im trying to connect to this module via arduino uno, can you create a manual how can i recive sms's from the arduino interface please
Thanks for the suggestion. The connection between the GSM module and whatever else you want to use (arduino in this case) is just a serial port so a slightly modified "serial hello world" script should be able to drive the GSM module. I don't happen to have an arduino handy for this though. Have one you want to send me?
Anders Brownworth thanks i will try that, i will update you if i secceed
In the typical case, yes you do have to pay for the calls if you have a SIM from a public network. In my case, I am running my own private BTS so I don't have to pay. (see my video on that on youtube at: pTb1_v8M6iA)
