Setting BMS772

[Auvidea-AS]

Hello,

We connected

 NXP-BMS772 (J3) with actual firmware from git to

orange cube (can1) with PX4 Pro v1.14.3.

On CAN we logged 18 frames per second but in QGroundControl the LiPo pack is not visible ?

Are there any setting required ?

PS:

Can log with HL-340 ( 1000000 Baud )

You need to use the latest BMS reference SW, BMS release version 6 that was just released to have DroneCAN support.
It's available as https://github.com/NXPHoverGames/RDDRONE-BMS772/tree/main
The github documentation has been updated accordingly.

To get droneCAN running the following parameters needs to be set via console:
bms set can-mode DRONECAN
bms set dronecan-node-static-id 31
bms set dronecan-bat-info 1
bms set dronecan-bat-info-aux 1
