Connecting to serial bluetooth

Post by Dzandaa »

Hi,

I'm developing a QT program to control a Bluetooth robot.

I have a problem connecting to the serial Bluetooth port.

/dev/rfcommx (0, 1, etc...)

I can access it in root mode
echo "a" > /dev/rfcommx
without problem.

But not as an user.

I got "Device or resource busy"

The user is already in the dialout group and can connect to standard Serial ports (Arduino, etc...)

I use Linux Mint 18.3 64 bits

I also use Bluetooth manager to connect to my serial bluetooth.

Any idea?

Thank you.

OK

I found the solution, another program is using the Bluetooth by default, removing it and it's working now.
