I have 4 DIY LIFEpo batties 4S i build with JK BMS. I added the new Plink boards so i could parellel the comms of these batties and connect to my Cerbo GX. when i installed the serial Batt driver the gx does detect the can bms. but dont show any info. only the battery voltage. The can logs show the bms is detected as Lljdb and not JK. what??? See log below. anyone know whats wrong here. BMS firwmare Ver. 19.17

CAN protocal is 4. victron canbus.

weird i got it to work but i had to switch the CAN protocal to 0 JK BMS CAN.

Well crap. it worked on the test Pi GX. with the Can Hat. but dont work in my live Cerbo enviroment on a BMS Can port. it is detected but no telemtry. only voltage. Not sure what im doing wrong.
