My final post, for anyone who comes across this thread in the future. I was never able to get any of the 11 bit BMS specifications to work, recpro, SMA, victron, etc. And I never figured out why. I contacted Wakespeed who sent my questions to one of their engineers, but he didn’t look at any of the logs I sent, just sent back a generic response saying check the BMS specs.
So I tried again with the 29 bit RV-C spec, which is not proprietary, and that works. Since I didn’t implement receiving messages or sending messages to specific nodes, it’s really no more complicated than the 11 bit specs.
The project is on github under xtoddmcx/dbus-to-rvc. It is not meant for public use and probably isn’t coded well, but it might be useful as an example.
Included is a screenshot of a candump, the highlighted lines are the outgoing BMS messages.
