Maker notes

Which role?

Beacon — a self-powered sensor node: it reads its sensors and beacons them over the LoRa mesh. Deploy it standalone in the field.

Gateway — bridges the LoRa mesh to a host running the Hover proxy so mesh traffic reaches the cloud, over either the USB cable or Bluetooth. One firmware serves the companion protocol on both links — pick whichever connection the host has.

Repeater — a high-altitude relay (balloon/aerial): it rebroadcasts LoRa beacons so nodes too distant to reach the gateway directly still get through, extending mesh range. It also reports its own GPS position.

No port in the picker? Install the USB-serial driver

The T-Beam Supreme S3 uses a CP210x or CH9102 USB-serial chip. If no port shows up when you click Install, install the driver, replug, and retry:

Confirm the boot · serial @115200

After flashing, tap RST and open a serial monitor at 115200 baud. A drifter prints its boot banner and LoRa beacons; the gateway prints its bridge startup (over USB or Bluetooth).
