Default to retained history with a separate pending count, and add persistent display.inbox CLI modes for history, pending, and unread. Preserve browsing while clients are connected and show the active USB or Bluetooth connection.
Fixes#5
Persist separate display modes and timeouts in seconds for battery and USB power, expose four controls in WebConfig and CLI, and apply one shared policy across display-equipped roles.
Detect R8 external power from a USB host or calibrated battery voltage above 4.21 V, with cached sampling and hysteresis. Add policy, persistence, browser, and R8 power-detection regression coverage.
Reserve board-specific GPIOs, make ESP-NOW channel/format handling configurable, and coordinate WiFi, BLE, NTP, MQTT, and host actions safely.
Add the Indicator message page, exclusive transport selector, dynamic 480/320 rendering, larger transport typography, pairing cleanup, and corresponding tests and documentation.
Add the framed BLE mOTA transport and companion control path, complete the full-profile build and runtime fixes, and document and test the OTA workflow.
AUTO_OFF_MILLIS is a power-save feature aimed at battery use. When the
board reports isExternalPowered() == true (USB or other DC source),
blanking the screen serves no purpose — there's nothing to conserve.
But OLEDs are vulnerable to burn-in with static content, so this
behaviour is gated behind a new build flag KEEP_DISPLAY_ON_USB. Default
is unchanged from upstream — the display blanks after AUTO_OFF_MILLIS
on USB or battery. Variants that ship with an LCD instead of an OLED
(e.g. heltec_t096) can opt in by adding -D KEEP_DISPLAY_ON_USB to
their env, gaining always-on-while-powered without exposing OLED users
to burn-in risk.
When the flag is enabled, the implementation refreshes _auto_off every
loop iteration while externally powered, so the timer naturally counts
a fresh AUTO_OFF_MILLIS window from the moment power is removed —
no instantaneous-blank-on-unplug.
Applied to all three companion_radio UI flavours (ui-new, ui-tiny,
ui-orig). Boards without an isExternalPowered() override use the
base-class default in MeshCore.h (returns false), so battery-powered
behaviour is unchanged everywhere.
