@Daniela I hope you aren't exhausted by all these, but X would be cool comments. If not: A walkie-textie would be cool, something less expensive and fragile (as emilv said) than a smartphone with a keyboard instead of a touch screen. Is there a serial interface to gotenna?

I believe you're asking if there's a user interface to goTenna? If so, not in the current device. The UI is your smartphone -- the point is to conform to consumer behavior (i.e. the way you already text on your phone).

For longer periods of outdoor use, a low-power built-in text interface would be useful. Especially if the battery lasts longer than my phone's.

Is there an alternative to bluetooth-LE for talking to the gotenna?

Our first prototypes worked over the audio jack (à la Square) but from both performance and form factor perspectives, having it work wirelessly over BLE worked better. That being said we can work audio and other data interfaces into later products for sure, we're just going MVP route ;)
