Setting BMS772

Auvidea-AS — Fri, 07 Jun 2024 10:57:07 GMT

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

Hi,

Please also see How to integrate RDDRONE-BMS or MR-BMS771 in PX4 via DroneCAN | RDDRONE-BMS772 for the step by step guide including QGroundControl configuration.

Kind regards!
