Invalid Remote ID Serial Number

[Andrew Martin]

On a Starling 2 Max, I'm running voxl-remote-id to get the Remote ID serial number so that we can register with the FAA and fly. However, that script produces an invalid serial number, and I'd like to know your intended behavior. The format is supposed to be your ICAO ID ("1814"), plus the length (a value 1 to F representing the length of the next part, but which is hardcoded as "C" in voxl-remote-id/src/main.c), plus the manufacturer's serial number (which is read in from /sys/devices/soc0/serial_number). However on our drone, that last bit is only 10 characters long (e.g. 0123456789). In this case, the script currently generates a value of 1814C0123456789, which is invalid. The voxl-remote-id script definitely needs fixed, but how so? Should it be something like 1814A0123456789 or 1814C012345678900?

Hey @Andrew-Martin thanks for reporting, I also saw the gitlab issue. Have you tried increasing that buffer size and rebuilding ? We could try to provide you a test deb.

We just got the MVP of remote ID in place and kept this open source so we can fix as needed...

@modaltb This simplest fix for us was to just change the hardcoded 'C' to a hardcoded 'A' and rebuild the deb. It's not the "proper" solution, but it should let us fly legally.
