Many say the A7 consistently locks up after 80 or so calls and then requires a complete power cycle to recover. I do not know if they are not coding it correctly or it is an inherent design flaw in the A7 as they claim. Have you had this problem?
Hi Nice video . 2 Questions .. which 2 pins on A7 are you connecting together? The arduino code is no longer on the site links . Can you send the code seperately ? Regards
Hi, im using this module, but is it required to have alot of time to get a GGA senetence and what is preffered wire antenna to be use for this module. Im having a trouble in getting a fix GGA sentences.. Helpmesir, Thanks
CoyoteBoyUK yeah I was thinking about the same, no one shows that, I checked the layout In this module and the headers were connected directly to the pins on the A7, so I tried first with the level shifters and sometimes I had troubles with the communication, then I tried it without the level shifters and everything seems to works fine so.. 🤔
SORRY I'M FROM PERU , CAN YOU HELP ABOUT THE NUMBER PHONE ? I DON'T KNOW WHAT CODE OF NUMBER PUT THERE BECAUSE HERE IN PERU IT'S 9 NUMBERS ,HELP ME PLEASE , THANKS
SALUT. La communication entre rpi et le module A7 va se faire à travers les pins UARTs. Il faut alors brancher le pin UART_TXD ( Transmitter ) du module sur le pin UART_RXD ( Receiver) du raspberry, de même le pin UART_RXD du module se branchera sur le pin UART_TXD du raspberry. Pour le Raspberry 3, UART0_TXD est accessible via le GPIO 14 , et UART0_RXD via le GPIO 15. Par la suite, il faut brancher le GND du raspberry pi au GND du module A7.@@abdelrhmanelkomy2174
i tried your call.ino program, but it doesn't want to call to any phone number. my arduino uno is working, but i don't know what the problem, is my a7 ai thinker broken?
i tried the "call.ino" program from this video, i follow step by step from wiring between arduino and a7 ai thinker until i finish complile the codes, i try the serial monitor. in the serial monitor, program is working well(AT-ATD-ATH), but the program never want to call any phone number. i don't know what the problem the program never want to call any phone number, sir. i'm sorry for my bad grammar, i'm not good in English
call the number from other mobile is ok, i tried too the sim card from the a7 module in mobile the sim card can call to that number and other phone number
Send "AT+CMGF=1" then "AT+CNMI=2,2,0,0,0" and the module should display any sms sent to it, from there you can identify the sms (easier with keyword in the sms) and do whatever you want

Great video! Do you know if the module works with thingsmobile SIM?

If i will want to send message and Want the gps to send me the location what should i do ?! (i’m using a9g Gprs )
Can it be used without the antennas?

its showing AT commands but I am not receiving any message to my mobile
and me

How to get gps location via sms?
dont you need some level shifters between the TX-RX of the arduino and the TX-RX of the A7?
I would say yes, because the datasheet shows 2.8V max and most arduinos are higher than this. However no-one who's done a demo shows this.
CoyoteBoyUK yeah I was thinking about the same, no one shows that, I checked the layout In this module and the headers were connected directly to the pins on the A7, so I tried first with the level shifters and sometimes I had troubles with the communication, then I tried it without the level shifters and everything seems to works fine so.. 🤔
Well that sounds good then, are you using 5V I/O from the Arduino then or 3.3? That saves me building a shifter up so thanks for confirming it!
Finally I used it with 5 volts directly!
Awesome, thanks!
How do I get the actual coordinate values? Do I have to parse the values that I get or is there a function that I can use?
Thanks man, you helped my problem
how serial communication is configured please, I can not do it...

hi sir,would u mind to add wire connection diagram to make it clear? thanks

same as this
Hello. nice vidoo. so, can you help me please? I want to connect this module to my raspberry pi3. how can I do? help me please. Thanks.
hello did you know how to connect it to raspberry pi3?

hello sir, i just try the gsm demo, the output i get is "?????K" and so on. may i know why
Change the serial monitors frequency 9600buad to 125200buad.
I have a different model of the a7 GSM module. I have not been able to code for months, can you help me if i send a picture or its model?
Have u done with ur issue?
Hello
interestig,but,if i WANT TO CALL THE GSM WITH MY PHONE? (Gsm answer in no time..)
Hi i tried your gps program but its nothing to show
Hello, has someone sent latitude and longitude or a link to Google Map with an sms?
you found answer?
Hello i try to call a number ...with the module A9G...but the risult is this:
+CIEV: "CALL",0
the code is this --> "ATDxxxxx;
Thanks"
Thank´s....sucess with gps test
Sir. i try same as your video but why GPS value not displayed on serial monitor?
You need open space or have to use strong external antenna for both gsm & gps
i tried your call.ino program, but it doesn't want to call to any phone number. my arduino uno is working, but i don't know what the problem, is my a7 ai thinker broken?
give me more details description . i can't figure out your problem.

i'm sorry for my bad grammar, i'm not good in English
call that number from other mobile and check ring tone . by this way u can check everything ok or not.
call the number from other mobile is ok, i tried too the sim card from the a7 module in mobile the sim card can call to that number and other phone number
did you use same code that is given.. ? you can extend delay time to my code..
hi. can you please help me with receiving sms in this???
this module is compatible with 4G/LTE or not ????
can you put these programs as link? thanks
Can I supply voltage from arduino to module
No. It's not possible. A7 need upto 1 amp current.
Arduino Can not output that much current.
Hello sir, I didn't get the result for GPS. Can you help me with coding and the wiring to Arduino?
keep your device in open sky place.it will take little bit of time.
i tried your gps program but it only gives a random character pls help
carlo atienza, do you try in open place?
Can anyone help me to get the gps location??? Can anyone give me the code for gps
Vai , aita kothay kinte pao jai ? website link ?
hi sir.. i think you are not clear about wiring diagram.. can you add the diagram wiring
many thanks
I tried for call but its not workin
How can I use it with raspberry pi
yes it's possible . GPS A7 module communicate data through Rx Tx pin. Connect with raspberry pi
Can you help me with gps code ?
Can I send a message to this module and it resend me the location?
Send "AT+CMGF=1" then "AT+CNMI=2,2,0,0,0" and the module should display any sms sent to it, from there you can identify the sms (easier with keyword in the sms) and do whatever you want
Thanks
how i can add both gsm and gps code on arduino to know the location by sending msg
hello did you get your answer??
no :(
So did you solve it in another way
Hi Islam, this module A7 is both GPS and GPRS, but you need to find the GPS anthena: www.elecrow.com/wiki/index.php?title=A7_GPRS%2BGSM%2BGPS_Shield
@@jotasmall Yes, im having the same problem too. I cant get mostly a fix data and only random strings.
muy bueno
