What it is
A short tutorial by PatchBOTS showing how to pair two HC-05 Bluetooth modules as master and slave using AT commands sent from an Arduino Uno. The description adds troubleshooting notes on button timing at power-up, address format for AT+BIND, and baud rates.

I am a beginner to arduino and trying to follow one of the videos from youtube to make a project- Master And Slave using HC-05 modules. I followed every step from that video carefully. Here's the link to the video -> [this video] For Slave Module when I type AT commands in the serial monitor nothing shows up. I searched in Internet for the this problem and still didn't fix it. Here's What i have done: tired restarting my pc tried Changing arduino, At first i used arduino nano and then uno I tried changing the baud rate to all other values and nothing happened And there is no change in light blink, it stays on AT command mode until power is turned off and on again. This is how is looks [LINK] Than

I have two HC-05 modules the first one's role as a Master and the other is a slave one. I've done some AT commands to set up each HC-05 module = Master's configuration has to be like that: name=Master, Password=2021, only accept connection from one HC-05 module only (for privacy purposes) via the Slave's Address, Baud rate = 9600,0,0. = Slave's configuration has to be like that: name=Slave, Password=2021, Baud rate = 9600,0,0. The AT command I used to set this configuration like that: Slave: /*Set Slave mode.*/ AT+ROLE= 0 /*Setting up Baud rate (The same as the Master Baud Rate to proper connection).*/ AT+UART= 9600,0,0 /*Rename the module.*/ AT+NAME=Slave. /*Get the Slave address to save it
