Options to get odometer reading and reset odometer

[molleraj]

I noticed that my XOSS G Gen2 has an odometer and had read that it has a limit of 9999 km (or mi if using imperial units). Have you come across documentation for a command that fetches or resets the odometer? I can't see the odometer reading listed in workouts.json, panels.json, gear_profile.json, user_profile.json, or settings.json. Thanks in advance for any help!

I am not sure, but I guess it is stored in a system region as the serial number is.
I have no idea if this region is accessible via BLE and Nordic UART service. Maybe,
reverse engineering of the hardware is necessary.

If you had connected the terminals (pads, see the photo shown in batt_replacement.md)
inside the GPS device with a physical debug probe (e.g. j-link), you could have read that
region.

Ah OK cool! I thought I'd ask because I thought retrieving the odometer reading followed a similar format and used similar command constants as the command to retrieve diskspace (e.g., VALUE_DISKSPACE, OK_DISKSPACE). Perhaps [0x0b,0x00,0x0b] and 0x0c. Thanks for the recommendation! I'll have to get a debug probe and try on another unit.

There is, at least, a few GitHub account of people in XOSS.
One might be able to ask them (developers) directly.

Oh great point! Thanks for the links to XOSS developers. I will ask them and see what I can find. Thanks again!
