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 durable TempRadio, ACL, clock, bridge, GPS/I2C, USB logging, and Indicator recovery safeguards together with expanded automation, build/profile contracts, release metadata, and the hardware validation ledger.
Add selectable shared ESP-NOW channels, raw/wrapped bridge compatibility, and bounded fragmentation for maximum-size packets.\n\nGive ESP32 Full profiles WiFi coexistence, stabilize WebConfig and USB terminal lifecycles, and keep disabled bridges stopped during observer updates.\n\nUpdate generated UI, firmware selection, documentation, and regression coverage.
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.
Expose the Full Companion terminal over TCP and add an authenticated, replay-resistant host command service with documented CPU temperature, reboot, and allowlisted program examples.\n\nImprove LoRa OTA diagnostics and persistent CLI handling, reduce clock correction drift to ten minutes, and make mOTA stream flush behavior an explicit transport policy with regression coverage.
Picks up upstream MeshCore 1.17.1.
Notable upstream content:
- 1.17.1 version/build-date bump in the example MyMesh headers.
- nRF52: combine radio entropy with CC310 RNG.
- Companion FEM prefs: load/save of fem_ properties commented out until they
can be set from the client.
- Scoped reply routing: replies no longer dropped when flood.max.unscoped is
low (RoutingPolicy + unit tests).
- nRF52 unused-pin sweep (T1, T-Echo Lite, MeshPocket).
No conflicts.
Brings in the external FEM gain preferences (fem_txgain, PR #3137 plus the
companion-side port), the AGC reset rxgain fix, the LR2021 preamble/IRQ
timeout logic, and assorted variant fixes (T096, T-Echo Card TCXO, promicro
pinmap, minewsemi, R1 Neo).
Conflict resolutions:
- SH1106Display: both sides fixed T-Beam Supreme startup independently. Kept
our _initialized guard and DISPLAY_ADDRESS_ALT override, took upstream's
SA0-pair fallback and its unconditional display.begin() so the frame buffer
is allocated even when no panel answers.
- MyMesh/SensorMesh/CommonCLI: took upstream's fem_txgain default and wiring,
kept our comments and the observer-side prefs layout.
Also fixes CustomLLCC68Wrapper, which upstream missed when sx126xResetAGC
gained its rx_boost_gain parameter. No variant builds that wrapper today, so
neither tree failed to compile.
Picks up upstream MeshCore 1.17.0 and the dev commits that followed it.
Notable upstream content:
- 1.17.0 version/build-date bump in the example MyMesh headers.
- anon_req hardening: reply_path_len is now uint8_t with an isValidPathLen()
bounds check and a 0xFF sentinel; reply_path_hash_size is gone.
- LR2021 support (Meshnology W12, Seeed MeshTracker X1) incl. side detectors,
multi-SF and the new `extra.sf` get/set CLI.
- CustomLFS 0.2.2 -> 0.2.3 (GD25Q64C support).
- kiss_modem envs for several nRF52 variants; ThinkNode M6 GPS/flash fixes.
Conflicts resolved:
- platformio.ini: took upstream's CustomLFS 0.2.3, kept our lib_ignore for
the vendored PsychicMqttClient.
- CommonCLI.h: kept both upstream's USE_LR2021 configSideDetectors() hook and
our fault-alert callbacks.
NodePrefs gains upstream's extra_sf[4], which is not registered with
ConfigSerializer, so /prefs.json layout is unchanged.
Verified: 275/275 native host tests pass; Heltec_v3_repeater_observer_mqtt,
Heltec_v3_repeater and heltec_v4_repeater_observer_mqtt all build.
The full embedded string is v1.16.0.5-observer-beta-dev-a1b2c3d. The -observer
tag is on every observer build and the commit is for machines, so neither tells
a person anything at a glance. Both the page header and the console banner now
show base + published build number + channel, paired with the build date the
way `ver` pairs them:
v1.16.0.5-dev (6 Jun 2026)
v1.16.0.5 (6 Jun 2026)
`ver` still prints the whole string, commit included, for when that is what you
need. The channel suffix follows the release filenames rather than the embedded
tag — build.sh writes FILENAME_CHANNEL_TAG "-dev" for the same builds it tags
"-observer-beta-dev" internally, so "-dev" is the name these already carry.
Carrying the build date meant /api/status had to report it; WebConfigServer now
takes FIRMWARE_BUILD_DATE alongside FIRMWARE_VERSION, from the same defines
`ver` reads.
A local build has neither build number nor channel to show, so the fact worth
knowing about it moves to the second line: "local build, OTA not configured".
build.sh deliberately leaves OTA_MANIFEST_BASE undefined there, and a bare
version number gives no hint that the node cannot update itself.
