As understand it, some of the units have been flashed with a custom firmware that communicates with a binary protocol. After figuring out that it was communicating at a baud rate of 38400 instead of the expected default of 9600, I was able to read the following:
$PGMOD,,,,,,,,,
This is followed by about 20 more ,,,,,,,,, 's every second. I've left it outside for a while and verified that the 3Dfix pin is low, so it appears the unit is obtaining a lock.
I've also tried to send it the command to switch back to NMEA protocol: $PGCMD,16,1,1,1,1,1*6B , but no luck. I'd like to put it in NMEA mode as I need some of the information that isn't included in the DIYDrones binary packet.
Any thoughts?
Best,
Geoff

Next question, what are the commands to do the following:
1. Change the baud rate
2. Change the GPS update rate
3. Save settings to the onboard flash
The datasheets seem to be seriously lacking in describing their configuration commands.
Thanks,
Geoff
