The goTenna
The goTenna is a neat little device which permits peer to peer communication over distances without the need for an established wireless backbone (cell phone network) or radio license. Kind of neat. Here are some of my notes on the device.
Connecting
Connecting to your goTenna outside the official app will probably brick your unit. It might cause it to launch off your desk and off in to space. Who knows. Read this document at your own risk.
Connect the goTenna over USB to any desktop computer and it shows up as a "goTenna" (swell!), and exposes a serial port over USB. The driver seems to load in Windows 10, but not Windows 7. Linux is happy to load a generic ACM driver (like TTY but for modems.) Connecting to this serial port at 9600 baud gives us an undocumented CLI. I can't yet determine whether this mode is purely diagnostic or whether it might be possible to fully control the goTenna.
Periodically send a message over the serial port or else you'll get this message and the serial port will drop!

The Periodic Event
Every minute (?) goTenna outputs diagnostic information about the current state.

Battery voltage is what it says on the tin. PAP appears to be "PA Power", refer to the pap command documented below. RSSI is a pretty familiar RF concept.
CLI Behavior
The CLI seems to accept some valid commands with any extraneous trailing characters. For example, the version command can be invoked by versionxy, or version;, or version;temp;. Some commands will default given no arguments (pap for example), but some commands will report as unrecongnized unless an argument is passed (chn and ctx to name a few).
As of the latest firmware release, 0.23.2, the goTenna> prompt is no longer displayed.
CLI Commands
version
Show the goTenna firmware version. The version reported by the CLI is hexidecimally encoded (0x00, 0x12, 0x02), while the verion reported in the application is convered to its numerical equivalent (0, 21, 4).

pap [val]
Set the PA Power (PAP). Not sure what this is, or whether it's a great idea to change it. However, changing it doesn't seem to change the "selected pap" value that appears in the periodic event. The largest PAP that can be entered is 255. Larger values will be truncated to 255.

[366786-000] printer: cli-cmd = pap 2
batt
Get information about the battery. Issuing the command as battery works just as well, but this could be due to the cli ignoring extraneous trailing characters. The values this command gives are sometimes wonky, so several readings should be taken any outliers should be discarded.

flash
Perform a flash check? I'm a bit afraid of this command.

Seems to immediately reboot the device. Does not return any output. Your serial connection will drop as the USB device disconnects and reconnects.

temp
Read the internal temperature. Could be the temperature of the Freescale ARM processor or the Silicon Labs RF chip, not entirely sure yet. Given the preoccupation with the TRX (tranceiver?) temperature during send I would imagine this is temperature of the Silicon Labs RF chip.

Reset RF hardware? The Si4460, mentioned in the resulting output, is a High-Performance Low-Current Tranceiver by Silicon Labs.
Interesting to note, this command is sesensitive to trailing extraneous characters.
