my HC-06 version is 3.0 20170609 I want to use it in Master
The name and PIN change was successful.
Check ROLE 'AT+ROLE?' and answer 0 I know that 0 is the MASTER. Entering 'AT+ROLE:1' or 'AT+ROLE=1' and 'AT+ROLE1' will cause error (0) or no response. I want to know how to change from Slave to Master.
