Status: CURRENT (2026-10-18). Written for people who want to run Reticulum over the RNodes' second modem — (G)FSK or plain 2-FSK — instead of LoRa.
Flashing is out of scope. This guide starts from a device that already runs
the right firmware. Building and flashing it is covered by the RNode project's
own tooling (rnodeconf, the Arduino build, UF2/DFU upload) and by this
project's GFSK-STATUS.md §4–5.
