I suspect this might have to do with some missing python dependency ?

user@home:~/bluez$ pip freeze | grep miauth
miauth==0.9.6

I forgot to mention that I had to upgrade my dashboard from M365 to M365 PRO variant. This is a clone dashboard (for a XM365 PRO). It implements Nordic's NUS.

@n3rd4i Sorry for the late reply. The pip package did not contain the latest repo code. I have pushed a new pip version, please upgrade your miauth package with pip install -U miauth to version 0.9.7 and check if the issue still exists. Thanks!

Ok, with version 0.9.7 I've tried (kind of works now), command:

• miauth -m -f -s AA:BB:CC:DD:EE:FF

When success I get:

Namespace(command=None, fwver=True, m365=True, mac='AA:BB:CC:DD:EE:FF', nb=False, register=False, register_did=None, serial=True, token_file='./mi_token', verbose=False)

Sometimes I get:

I don't know if this the above is a problem or not, but the whole idea is to get battery SOC so I can shutoff charging if is 80%.

I'm thinking I need, -c but I've no clue what COMMAND actually is, where can I find docs about it?

  -c COMMAND, --command COMMAND
                        send command (w/o checksum) to uart and print reply
