I can have a look, but first I would need some documentation about the protocol that is used. Can you provide links or documents that describe the BT communication?

JiMcNulty commented 4 days ago

Sorry, didn't find docs like that But there is an android app So I guess maybe decompiling it would help?

patman15 commented 2 days ago

Ok, an Android app helps to reverse engineer the protocol. Can you provide information about the characteristics using e.g. nRF connect and a recording of the communication between the app and the BMS during the first ~30s? I don't want to interfere with legal issues, so no decompiling.
