Bluetooth module problem [Copy link]

I recently used the Bluetooth module HC-05. I first set the serial port baud rate to 38400, entered the AT command, and

Set the Bluetooth module to master mode, then power it on again, set the baud rate to 9600, and enter transparent transmission mode.

However, when I use the Bluetooth assistant on my phone to connect, the name of the Bluetooth is not displayed, and it also says that it cannot be connected.

Can any experts please tell me how to solve this problem? Thank you!

The Bluetooth module should be set to slave mode, with the phone as the master.
