The serial on this unit is #373. I tried using ao-load (Ubuntu 16.04, altos 1.6-1) to load a couple of different firmware revs, but it wanted a "map" file, which I eventually figured out was a symbol table I didn't have. So on a whim, I tried ao-rawload, and that worked. The TeleDongle connected over USB, and I was then able to re-flash it using the 1.9 AltosUI, manually fixing the serial number. I suspect I just hit some sort of transient error the first time.
However, I do think the RF calibration value is bad, because the TeleDongle won't talk to either of my TeleMega units OTA. Do you still have #373 in your database?
