Cannot bind bluetooth to rfcomm


I’m trying to bind a bluetooth device to a rfcomm serial port in order to send and receive raw data on my Jetson TK 1.

I keep getting the same error over and over: everytime I use the rfcomm command I get:

Can't create device: Operation not supported

I read that it may be a kernel issue, in particular tied to the rfcomm module.

This is the output of the lsmod command:

root@tegra-ubuntu:/home/ubuntu# lsmod
Module                  Size  Used by
btusb                  17111  0

rfkill                 10365  3 bluetooth
nvhost_vi               3064  0

It looks like that the rfcomm module is there.

The kernel I’m using is

root@tegra-ubuntu:/home/ubuntu# uname -r

Any ideas on how to get the rfcomm command running? Thanks

What is the output of

hcitool dev


I’m having the same problem.

The connected bluetooth-device is:

ubuntu@tegra-ubuntu:~$ hcitool dev
	hci0	18:3D:A2:D0:F5:38

Any ideas?
