I bought a Meshtastic compatible device, a Heltec V3 LoRa transceiver, to do some experimenting with the DIY messaging system. It can be used off-grid to communicate in situations where cell phones are not available, for example. I'm still learning how to use it. I have connected it to the MQTT server run by Chicagoland Mesh and have been checking out the group chat channel by replying to people sending test messages to let them know I saw them. I did see a message sent from an airplane passing through the Chicago area skies this morning which was pretty great.
