running gopro-photo

[maccardo]

I just installed the latest open-gopro from pipy (v0.16.1)
I also installed the gui demos.
I went to run the example gopro-photo and it returned an error.
I ran it as follows, with error.

Why am I getting insufficient authentication.

The Bleak Python interface is not very robust so depending on when / if you reset either device you can run into these types of issues. If you start with a fresh connection state as described below, everything should work:

Reset the camera by choosing Connections –> Reset Connections
Use your OS’s bluetooth settings GUI to remove / unpair the GoPro
