Probably you already have this, if not by any chance, here it is. Extracted from the android app. Hope it could be useful.

I did a btsnoop on the android app and seems the messages start with 5aa5,
e.g.
5a:a5:80:3e:20:08:00 + new firmware (firmware update)
5a:a5:01:3e:20:01:23 :06:76:ff (not yet sure what dose this do)

I read your code and seems the message starts with "\x55\xAA". Mine is ninebot es1. Is yours xiaomi m365?

Sorry, I’ve just noticed the message (need to set up some notifications). Thanks for the info!
The 5A A5 protocol is supported too, it’s in NinebotTransport class. Some tools here (more polished ones) have a -p parameter to choose the protocol. The 3E 20 01 23 06 cmd means “APP->ESC: read registers starting at index 23, length 6” (that’s in the protocol docs).
