>>2642It's a walkie-talkie for text messages. LoRa operates on frequencies which were used by paging companies in the past, and still used for radio keychains for cars/garage doors, they're colloquially called ISM band.
I don't like presence of bluetooth and gps functions on this thing, the idea glows suspiciously,a s well as lack of publicised fdroid distribution. The board should connect to phone via USB to avoid insecure wireless Bluetooth link to something you carry on yourself already, drop the ridiculous battery, and since phones already have GPS, it shouldn't have another one either.
