  Any idea why I would have lost the CAN comms between the BMS and the Cerbo GX when I upgraded to firmware v1.5? I didn't change anything else.

  Try resetting the CHRG and CANS parameters.  Details are in the new manual on the rec-bms-na.com site

  @Rick I figured that…

  I reset CHRG to 1, CANS is still 3 which I believe to be correct for the Cerbo's 500 kbit CAN-BMS port. Still nothing, unless I need to reset/reboot something to get that to take effect.

  Thanks for the fast response!

  Yeah, it's still not happy:

  

  I don't see any packets there, from the REC, eh?

  A full reset, completely powering off the REC, resolved it.

  Great, glad you got it working.  For reference, if you want to move to the VE.CAN port here is a quick video to help setup the BMS and the Cerbo.
