Me again. So I ran a couple of air jobs several times with no problems through Chilipeppr (with the newest version of the serial-port-json-server). That got my confidence up, so I attempted to upgrade the firmware on the TinyG.
Under Windows, the TinyG-Updater failed right away with a "verification failed" error in the progress bar (which was red).
Switched to Linux (Ubuntu 14.04), grabbed both edge and master copies of the firmware, downloaded version 1.6.1 of the Arduino IDE to get avrdude, then did this:
./arduino-1.6.1/hardware/tools/avr/bin/avrdude -p x192a3 -c avr109 -b 115200 -P /dev/ttyUSB0 -C ./arduino-1.6.1/hardware/tools/avr/etc/avrdude.conf -U flash:w:tinyg-edge-440.14.hex
Which resulted in this:

This doesn't seem like the Firmware Verification failures as documented in the wiki. Any suggestions?
