How do you connect two HC-05?

How do you connect two HC-05?

Step 5: To Configure and Pair Two HC-05 As Master and Slave (Step 3)

1. AT+RMAAD (To clear any paired devices)
2. AT+ROLE=0 (To set it as slave)
3. AT+ADDR (To get the address of this HC-05, remember to jot the address down as it will be used during master configuration)
4. AT+UART=38400,0,0 (To fix the baud rate at 38400)
