Question
How do I fix the permission denied issue so that the hci0 device can be accessed using hciconfig and/or hcitool?

Problem resolved.

[Guido Forthofer (guido17)]

Currently I have same problem, how you solved this?

[Tony Espy (awe)]

Updating this bug to Incomplete, as the original reporter said his problem was resolved.

@Guido, if you're using a newer version of this snap on Ubuntu Core and are still having problems, please provide the relevant details.
