I am setting up a system using DroneCAN servos, I was hoping I would have rich logging of the CAN Bus statistics, particularly any apparent packet loss, as I have a drone which undergoes some pretty harsh electrical transients. When I read the real time stat page in the DroneCAN section I at least get a count of frames eliminated for errors.
But in logs the only fields that seem to be populated are CANS.T and CANS.R which is simply the total number of frames. Even when I observe Rx errors on the real time stats page they are not recorded under CAS.Rer. Which is not particularly helpful for diagnosing potential systemic/electrical failures on the CANBUS.
I have set “enabled stats” and “flexdebug” under the CAN_D1_UC_OPTIONS bitmask, which I thought would account for this.
Is there some secret location that actually meaningful CAN statistics gets dumped to in logging or is this functionality just not implemented yet?
