Describe the bug
I have been walking through each demo to try run on a Raspberry Pi. I got all the way to provisioning the cohn to get the certificate and I get the following:

I am dealing with the same issue on a Hero 10. It looks the like its failing to assert response.status == 0x00. The returned status code is 2 not 0. The setting of the date and time is a TLV Command, looking at TLV Command responses in the docs status code 2 is indicated as Invalid Parameter.

[tcamise-gpsw]

The problem is that the tutorials are only supported on the latest camera (Hero 13 currently):

Specifically, the set date time command you are using does not exist on Hero 10.

Furthermore, COHN as an entire feature does not exist on Hero 10.

Tim with your help I used livestream.py and was able to getting working. Doesn't that use COHN? Thanks again
