How do I get bluetooth interface accepted

How can I get my bluetooth interface accepted by Wireshark?

Get an error message, which I have googled on the internet and searched here in Wireshark.

The capture session could not be initiated (Can't attach to device 0 22:Invalid argument).

Please check to make sure you have sufficient permissions, and that you have the proper interface or pipe specified.

Running su root at present in PCLinuxOS Mate 64 bit. System will catch fine if I change to eth0

Edit: Discovered later, following can be seen in root,
