What a fantastic introduction to the subject. Thank you so much for explaining it so clearly and concisely. You have given the confidence to get started on the project I had in mind.
The one hc-05 is not the master. YOU ARE THE MASTER! Thank you for the great video
Finally I got some instructions of how to set up a potentiometer. Thank you so much. Greetings from Brazil!!!
A very good tutorial. You've included alot of important information many others have neglected to give. Such as in AT COMMAND mode the RX and TX pins are reversed! That proved very frustrating for me when trying these out the first time.
Great video sir, informative and helpful, thanks a lot sir,this video helped me in completing my project
Nice and simple explanation. Am I the only one who's gonna tell you NOT to use red wires for GND and blue and black wires for +5V? Come on mate, that's totally insane haha.
i cant thank you enough for your great tutorial, i certainly learnt alot , i echo smooth jamie comments that you have a great grasp of your subject and include information generally omitted thanks again
Its working, thank you sir🙏
The most helpful video I've encountered. Thanks!
Sir this the bestest and the most benifcial video on pairing of bluetooth! thankyou soooo much ! #GOOD_WORK !kee it up :)
Ammar can we connect bluetooth headset to bluetooth speaker to make it pblic addess system??
Thank you very much sir,
understood very clearly,
tried and its working good
Hello sir this is the only one video which I get on youtube. Can you share that how to send the data from three potentiometers at A0, A1, and A2 from first Arduino uno to second Arduino uno using two HC05 modules. I am not able to differentiate three outputs on receiver end.
If you get any relevant information regarding this please let me know ,im struggling at this point too
What degree should i take for me to understand exactly whats going on here? I’ve always wondered how to build and code things.
VERY INSTRUCTIVE. THANK YOU FOR SHARING KNOWLEDGE
AT Commands won't appear on the serial window, what could be the reason?
Thank you very much! Very helpful and clear.
I want to make my audio devices in the living room wireless (I heard Bluetooth is better suited than wifi?) and thought I would need to buy a transmitter board for every device (vinyl player, DVD player, amplifiers and a tuner so four Boards?) and then I need to get arduino Set Up which will then basically receive all the Bluetooth signals right? I connect the output of the arduino to my speakers and subwoofers and should be fine right? Please someone help me out with this I am so confused.. Thanks guys, stay well oh and nice video btw
How to differentiate (identify) which data received from which slave device?
My bt HC-05 was blinking both led. But after ORGL command it is blinking only red. What is the reason?
What were all the piece that were used in this video?
Great explanation sir, thanks
If i want to control multiple LEDs to be dimmed , if i send the code as serial print, won't the data be over written? How do I distinguish between the datas🙁
Can we do audio transfer using this but without using aurdino.only once use is ok.
How to use these modules to make wireless connection between amplifier and subwoofer?
can we send data from button and pot to the slave in same time ? and How ? briefly
What's the range distance the slave and master can communicate?
Wow thank you very much soooooo helpful
Very Nice Thank you so much 👌👌👌
Can you help me connect Bluetooth module to a weighing scale?
what happends if I set cmode to 1 and link an addres?
Thank you for this nice video!
what if there is multiple slave module need to be bind? how the AT command work?
informative video! thank you.can the hc 12 be programmed similarly?
hc bluetooth is paired with mobile but not connected. how to solve it?
Good video sir tnx
(it was showing 21,13,AD4E when the real was 0021,12,00AD4E)
Hi, i have a doubt in Bluetooth module. I want to reset or ON OFF the Bluetooth module when android device disconnected. Is it possible??????
Thanks for the video sir .... Plz make a video on how to store the data received from Arduino (analog read data via Bluetooth) to a text file and store the text file in a shared folder like Documents folder of internal storage... I am trying for this but not successful...
what is AT
I don't have button on my hc-05 .. what should I do?
In some HC05 BT module there is no button how to configure that sir
Hi, I need to put a transmitter on the collar of my dog, so when he barks it would trigger a device in the house. I also need to keep track of the barks on an app on my phone that I will later make. What technology do you recommend? How? Thank you so much.
There is no reason to mark with stickers the BT modules.
Both modules, master or slave, can send and receive data.
After pairing of slave and master this module can connect any other devices
Thank You
very much helpful sir
How to use 2 pots and servo sir(unidirectional master to slave)
Sir how to Transmit audio through this or sir how to make Audio transmeter please guide
God bless you for your great patience
Rt809h ka link and how can install in laptop with tool chain please make a video complete thanks
Thank you for the video...☺️
getting port busy error when trying to connect to BT serial.
gracias por sus videos
I want an app which the sends Mobile notification as a command to hc-05 bluetooth module .please help me anyone
very good tutorial.
but what if attiny85 is sending its data via bluetooth hc-05 to arduino? how to program?
Useful video
how to configure without button module ?
i followed as you mentioned sir but i am not able to pair
I can use it on printer
Hi, Thank you for this nice video. Can we connect the HC 05 to AT Tiny 85 with corresponding Changes to Pin Numbers? will this configuration work ?
Thank you nice video
After pairing set connection according to the baud rate of the module. Mine was 9600.
great video
Hello sir, can i use all the analog input at the same time to transmit it in the receiver? Thanks you a lot.
I put bluetooth on AT + ROLE = 2 now does not go out, even in configuration mode, if I put AT answers AT and not OK. How do I get out?
Put AT + ROLE = 0 or AT + ROLE = 1
MY HC-05 MODULE IS NOT POWERING UP OR NO LED IS BLINKING
IF ANYBODY KNOW TO REASON PLEASE HELP
Congrats
SIR please make a vidio for WIRELESS UPLOAD the sketch to audrino uno with my android phone blootooh to audrino uno with the help of hc05 BT MODULE.
Dear sir.. can I able control 3 slaves using one master Bluetooth module
You can not connect/control more than one slave in same time. You can control
it *alternately* .
@@aaronabel_ alternative means how?? Can u explain?? I am planning to control three lights using one master Bluetooth module..
to: Sarvanan AL ; Can you make a bluetooth Scan ( Ardruino+ Hc 05 or 06 ) to scan the defference bluetooth device nearby !, as an Ibeacon (BLE) ..... and you have a video !! thank a lot !
Can u help me for
3 leds on of in 3 switches
To control
Send me code
baud rate 9600 and 38400...neither one works. There's a reverse question mark character on the slave serial monitor
having the same issue.. did you find any solution yet?
@@akkitheguy nope, I had to abandon the project because I could not get it to work.
Baud ret 9600 both arduino
Rt to tx
Tx to rx
Resister use for volt drop use in bt module rx pin
Same prblm fac then try try try
Then i fix thes
My questn is how to controll 3 led in 3 switch

Great video, Can you make video on how to send data from one master to multiple slave And if possible vice-versa also . As it can paired upto 9 slaves.
A master can pair with 7 slaves ,but at a time only one slave pairs with master.When a slave is switched off , other slave automatically connects with master.
But only one slave can be connected at one time. This means, to create a network you need to connect, get data, disconnect to each module in turn.
PICONET is the network term for bluetooth .But piconet firmware cannot be uploaded to the HC05 modules
Hi Saravanan, can this pair(master and slave) of bluetooth be worked as bidirectional ?
Rahul Kumar try rf
which rf module ? can you specify the name ?
it would have been very useful if you could have given an example of one master talking to two slaves and the connect-getdata-disconnect process happening.
Could you do a simpler version where you use a single bluetooth sensor HC-05 to receive data from pc via arduino. We want to receive data through HC-05 to our android phone via arduino. We want to receive the sensor values. Please reply ASAP.
Hello, can you suggest me how to transfer and read the data display on LCD to android via HC05 interfacing pic16f877a?
My device is not getting set in to master mode when i try to chnage role it doesnt respond ,, how to fix please help me
Sir kya ham mobile ke bluetooth ka mac address use krke auto connect kr sakte hai agar mobile ke Bluetooth ko solve and module ko master banaye to kya dono connect ho sakta hai plz ans yas or no
Qki yesh ko v bluetooth application hi nhi hai jo auto reconnect option provide kraye apke knowledge me ho to bataye
My Bluetooth module didn't connect to mobile? How can I fix this issue
Please guide me
