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.

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.

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

Finally I got some instructions of how to set up a potentiometer. Thank you so much. Greetings from Brazil!!!

The one hc-05 is not the master. YOU ARE THE MASTER! Thank you for the great video

The most helpful video I've encountered. Thanks!

Thank you very much sir, understood very clearly, tried and its working good

God bless you for your great patience

Thank you very much! Very helpful and clear.

Great video sir, informative and helpful, thanks a lot sir,this video helped me in completing my project

VERY INSTRUCTIVE. THANK YOU FOR SHARING KNOWLEDGE

Thank you for this nice video!

informative video! thank you.can the hc 12 be programmed similarly?

Great explanation sir, thanks

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.

Sir this the bestest and the most benifcial video on pairing of bluetooth! thankyou soooo much ! #GOOD_WORK !kee it up :)

Thank you for the video...☺️

gracias por sus videos

Its working, thank you sir🙏

Thank you nice video

very much helpful sir

Wow thank you very much soooooo helpful

Useful video

Very Nice Thank you so much 👌👌👌

After pairing set connection according to the baud rate of the module. Mine was 9600.

After pairing of slave and master this module can connect any other devices

great video

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

what if there is multiple slave module need to be bind? how the AT command work?

Good video sir tnx (it was showing 21,13,AD4E when the real was 0021,12,00AD4E)

AT Commands won't appear on the serial window, what could be the reason?

very good tutorial. but what if attiny85 is sending its data via bluetooth hc-05 to arduino? how to program?

How to use these modules to make wireless connection between amplifier and subwoofer?

Thank You

What degree should i take for me to understand exactly whats going on here? I’ve always wondered how to build and code things.

Can we do audio transfer using this but without using aurdino.only once use is ok.

What were all the piece that were used in this video?

Congrats

How to use 2 pots and servo sir(unidirectional master to slave)

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?

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??????

Can you help me connect Bluetooth module to a weighing scale?

In some HC05 BT module there is no button how to configure that sir

I can use it on printer

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 !

getting port busy error when trying to connect to BT serial.

what happends if I set cmode to 1 and link an addres?

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🙁

How to differentiate (identify) which data received from which slave device?

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.

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...

i followed as you mentioned sir but i am not able to pair

There is no reason to mark with stickers the BT modules. Both modules, master or slave, can send and receive data.

I don't have button on my hc-05 .. what should I do?

My bt HC-05 was blinking both led. But after ORGL command it is blinking only red. What is the reason?

Rt809h ka link and how can install in laptop with tool chain please make a video complete thanks

how to configure without button module ?

Sir how to Transmit audio through this or sir how to make Audio transmeter please guide

MY HC-05 MODULE IS NOT POWERING UP OR NO LED IS BLINKING IF ANYBODY KNOW TO REASON PLEASE HELP

I want an app which the sends Mobile notification as a command to hc-05 bluetooth module .please help me anyone

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.

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?

Hello sir, can i use all the analog input at the same time to transmit it in the receiver? Thanks you a lot.

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.

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 ?

Can u help me for 3 leds on of in 3 switches To control Send me code

Dear sir.. can I able control 3 slaves using one master Bluetooth module

Hello, can you suggest me how to transfer and read the data display on LCD to android via HC05 interfacing pic16f877a?

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.

baud rate 9600 and 38400...neither one works. There's a reverse question mark character on the slave serial monitor

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
