COHN tutorial failing on GoPro Hero10

[kmatzen]

I have several GoPro Hero10 with the GoPro Labs firmware. I'm attempting to provision COHN using tutorial 9. However, several requests are failing.

(1) Set local time fails

INFO     tutorial_logger:provision_cohn.py:36 Setting the camera's date and time to 2025-03-05 20:11:57.859386-08:00:-480 is_dst=False
DEBUG    tutorial_logger:provision_cohn.py:56 Writing: 0c:0f:0a:07:e9:03:05:14:0b:39:fe:20:00
DEBUG    tutorial_logger:decipher_response.py:161 Received response at GoProUuid.COMMAND_RSP_UUID: 02:0f:02
DEBUG    tutorial_logger:ble_command_get_hardware_info.py:100 self.bytes_remaining=0
ERROR    tutorial_logger:provision_cohn.py:259 AssertionError()

I commented out the set_date_time call since I already manually set my clocks. The cameras successfully connect to my wifi.

(2) Clearing COHN cert fails

INFO     tutorial_logger:provision_cohn.py:228 Provisioning COHN
INFO     tutorial_logger:provision_cohn.py:73 Clearing any preexisting COHN certificate.
DEBUG    tutorial_logger:provision_cohn.py:85 Writing: 02:f1:66

ERROR    tutorial_logger:provision_cohn.py:259 AttributeError("'TlvResponse' object has no attribute 'feature_id'")

I seem to be getting a TLV response when a protobuf response is expected?

I don't have a COHN cert yet, so I commented out clear_certificate.

(3) Create COHN cert fails

INFO     tutorial_logger:provision_cohn.py:107 Creating a new COHN certificate.
DEBUG    tutorial_logger:provision_cohn.py:119 Writing: 02:f1:67
DEBUG    tutorial_logger:decipher_response.py:161 Received response at GoProUuid.COMMAND_RSP_UUID: 02:f1:02

ERROR    tutorial_logger:provision_cohn.py:259 AttributeError("'TlvResponse' object has no attribute 'feature_id'")

This one too seems to be returning a TLV response instead of a protobuf response?

I stopped there since I can't create a COHN cert.

nvm, I now see in the docs that it's a Hero12 and Hero13 feature.
