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.

Re: Connecting to serial bluetooth
OK
I found the solution, another program is using the Bluetooth by default, removing it and it's working now.
