  • I have been playing around with the AT commands of HC-05 recently. Here's what I have found,

    ->AT+CLASS?
    1f00
    ->AT+CLASS=508
    OK

    This will show HC-05 as an INPUT device(GAMEPAD) on your system. We are able to pair to the gamepad but not connect to it.
    On the datasheet they also say it can be configures as a Master device aswell.

    ->AT+ROLE?
    +ROLE:0
    ->AT+ROLE=1
    OK

    where, 0 is for slave, 1 for master, 2 for slave-loop
    But when I configured it as a Master device it stopped showing on the bluetooth devices list.
