HC 05 Bluetooth - AT commands while linked

Hi guys !

I'm trying to program a multiclient app with HC 05 bluetooth chips.
When I link the master to the slave, then it's impossible to send AT commands
to the master. I mean, it interprets commands as a normal message to send
to the slave ...

I'm looking for a solution to manually unlink the chips, but by serial command.

Do you guys know a way to do it ?

Thank you !
