I have recently built an Android app that creates a nearby M-to-N mesh using the phones Bluetooth radio (BLE). This allows for nearby text messaging with no additional hardware. This is working quite well so far, but the range is obviously limited. I’ve used goTenna for a long time (since first gen) to do off-grid communication with one other person. Now I am thinking of combining the ideas and using goTenna to act as a “bridge” between two hyper-local M-N mesh nodes. Something like this:
Would anyone else be interested in use case like this? One of the main benefits is that you can link to disparate mesh networks using only two goTennas.
