All packets received from the MeshCore mesh via the observer node.
The observer location is fixed (green). Nodes advertising coordinates via the mesh appear automatically as packets arrive.
A Heltec V4.3 listens on LoRa 868 MHz running MeshCore observer firmware. A Raspberry Pi 4 acts as companion — forwarding packets to both DutchMeshCore collectors and the LetsMesh analyzer via MQTT/WSS.
ESP32-S3 board with SX1262 LoRa transceiver and 0.96" OLED. Runs MeshCore observer firmware and forwards packets to the Pi via USB serial.
Runs the MeshCore companion app. Receives packets from the Heltec over USB serial, then forwards to collector1 + collector2.dutchmeshcore.nl and the LetsMesh analyzer over MQTT/WSS.
The Heltec listens on LoRa, forwards over USB serial to the Pi, which pushes to both DutchMeshCore collectors and LetsMesh. This page connects directly to the DutchMeshCore subscriber endpoint to display live data.
