I'm trying to setup a bluetooth serial port on the PI3, but cannot manage to get it to work. In bluetoothctl I can find the devices (on scan), pair and trust the device, and connect to the device. Connection is successfull.
However, I need to connect to the device over serial port. How can I set up the device as a serial point? I've looked into rfcomm but not sure if thats the right direction. Can someone advise where to go from here?
rfcomm is the direction
it has been discussed recently
with bluez5 (on jessie) there is not the rfcomm.conf file, so you have to do manually
once you have paired and trusted the device in bluetoothctl, exit and do a rfcomm bind rfcomm0 xx:xx:xx:xx:xx
then check if all is ok (so try using yout rfcomm0 port)
if this is ok, you can automate the bind command editing the bluetooth service file (you can find how on this forum)
