>_ RNode Settings Menu
RNode's settings menu is a small on-device UI built into the firmware. This guide covers opening it, moving around, and what each screen does — no cable, no companion app.
Supported boards
The settings menu currently ships on these boards.
More boards will gain support as the firmware adds them.
Opening the menu
Long-press the main button for three seconds to open the menu.
Which settings you see beyond that depends on the board: what's really populated on it (a WiFi chip, an encoder, and so on).
What's inside
The top-level list. A few entries only show up on certain boards — noted where it matters.
Mutes the buzzer entirely. Off by default on boards where the buzzer is a DIY add-on most builds skip (ProMicro/FakeTec); on by default everywhere else. Doesn't appear at all on boards with no buzzer hardware (Heltec LoRa32 V4, T114, T096, MeshPoE-S3).
Lets you set the WiFi mode, SSID, and PSK password, entering each character manually with the encoder.
Diagnostics: CPU temperature (ESP32-S3, nRF52), input voltage, battery voltage, WiFi IP/netmask/MAC, Bluetooth MAC, Ethernet MAC (MeshPoE-S3) — whichever of these your board actually has. Most fields are read-only, but Input Voltage can be clicked to adjust its divider ratio.
Reassigns the buzzer, or the encoder's Up/Down/Press pins, to a different free GPIO — useful since builders wire these to whatever pad was spare. Won't let you assign the same pin twice. Takes effect on the next boot.
Recalibrates the battery percentage scale by hand.
Saving changes
Everything you change is staged in RAM while you browse — nothing touches EEPROM, and nothing reboots, until you commit and exit the menu.
Committing writes the changed settings to EEPROM and reboots the device only where a setting actually needs it.
