ADVMesh

A handlebar-mounted group-ride computer for adventure motorbikes. It pairs a Heltec LoRa32 V4 running MeshCore companion firmware with the app, so a group of riders can see each other on an offline map and text each other over LoRa with no phone and no mobile coverage. What it does One channel is active at a time, and the whole app is scoped to it — the map, the roster and the chat show that channel and nothing else. Group map. Every rider on your channel appears on an offline map with heading, speed and age-of-fix. Your own position comes from the Heltec's GPS, with a button to switch that receiver on and off. Channel chat. Create or join public, hashtag or private channels. Private channels get a freshly generated 16-byte key with show/hide and regenerate, shareable by on-screen QR code. Channel roster. Who has been heard on this channel, with distance and bearing. Repeaters and room servers stay out of the way on a separate diagnostics screen. Navigation. GPX track following with off-route warnings and a trip computer, plus distance/bearing to any rider or waypoint. Telemetry. GPS fix quality, temperature, humidity, pressure and battery from the Heltec. Offline maps. Street, topographic and satellite layers packed onto an SD card, selectable per layer, with an on-device Wi-Fi downloader for topping up a region. Rider identity. Assign a photo or logo to each rider, and choose whether to broadcast your own position at all. Camera. Scan a QR code to join a channel, take geotagged photos, and record video to the SD card with a dashcam loop.
