Does ATAK (FreeTak I assume) run pretty well? Are you just saving everything to the sd card?

I have had a similar project set bouncing around in my head. I have some LilyGo LoRa radios arriving soon to see how well Meshtastic works as an alternative to internet.

I am running the Pi from a solid state hdd as I don't trust the sd cards. ATAK/FreeTak does run well on it. Funny you mention LoRa as I am using exactly that. I have a bunch of the TTGO T-beams (915 MHz) that I have paired up with old Android phones that run entirely off the T-beams/Meshtastic. They can be slow at times for messaging, but it really depends on the channel setting (short range vs very long range).
