How do you use a Bluetooth module with STM32?
First, upload the program to the STM32 Blue Pill and then make the connections as per the circuit diagram. Then go to the Bluetooth Settings on your Android Smart Phone and pair the HC-05 Bluetooth Module. When pairing for the first time, it will ask for a pin. In that case enter 1234 or 0000.
How do I pair 2 HC-05 Bluetooth modules?
Step 5: To Configure and Pair Two HC-05 As Master and Slave (Step 3)
- AT+RMAAD (To clear any paired devices)
- AT+ROLE=0 (To set it as slave)
- AT+ADDR (To get the address of this HC-05, remember to jot the address down as it will be used during master configuration)
- AT+UART=38400,0,0 (To fix the baud rate at 38400)
What is HC 06 Bluetooth module?
The HC-06 bluetooth module is a slave bluetooth module designed for wireless serial communication. It is a slave module meaning that it can receive serial data when serial data is sent out from a master bluetooth device(device able to send serial data through the air: smart phones, PC).
How do I reset my HC-05 Bluetooth module?
Configure with AT Mode: After the connection, If you Plug the power source, you will see the HC-05 power on with short rapid blink, which is standard pairing mode of module. For At Mode, you need to plug the power source while holding down the reset button on the module.
What is the range of Bluetooth module HC 05?

How does STM32 work with hc-05 Bluetooth?
A simple Bluetooth terminal App on an Android Smart Phone is used to communicate with HC-05 Bluetooth Module to transmit some data. The STM32 will then decode the data and turn the on-board LED ON or OFF.
Why is my hc-05 Bluetooth module not working?
Everything is fine when i input the values from the serial monitor. The problem only occurs when I use my phone. I am using a bluetooth terminal for HC-05 and it shows it connected. The bluetooth module is conected as its blinking slows down when I use the app.
What is the PIN code for hc-05 Bluetooth?
The default password (PIN Code) for pairing with HC-05 Bluetooth modules is “1234”. You can check this information by typing in “AT+PSWD?”. It’ll respond back with the current password value. HC-05 Password Change
How to connect hc-05 to USB TTL module?
Open a new serial COM port (for the USB-TTL module as shown in your windows device manager) Type in “AT” and hit the enter key to send this command to the HC-05 module. If everything is working correctly, it should respond back with an “OK” message.
