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.
Improve companion BLE delivery and idempotent remote CLI retries, make FPF7 persistence atomic with FPF6 migration, verify staged OTA data on resume, and clarify filter policy wildcard and BlackHole semantics.
Neighbors publication was gated on BOARD_HAS_PSRAM. Removing that gate alone
was not enough: the feature built but was inert without PSRAM, because three
allocation sites asked for MALLOC_CAP_SPIRAM (which returns null with no
PSRAM), the bridge's persistent buffer was allocated inside a BOARD_HAS_PSRAM
block, and neighborDiscoverReady() rejected every pass at runtime on
psramFound(). The entry table also did not fit: finishNeighborDiscover put
pubkey_hex[50][65] plus entries[50] on the stack, a 4752-byte frame against
the mesh loop task's 8 KB.
- Gate on MAX_NEIGHBOURS plus PSRAM or an explicit per-variant
MQTT_NEIGHBORS_WITHOUT_PSRAM opt-in.
- Move the entry table and its hex strings into one heap block sized to the
pass; the frame drops from 4752 to 304 bytes.
- Prefer PSRAM and fall back to internal DRAM in the mesh-side allocations
and the ArduinoJson pool; hoist the bridge's persistent buffer out of the
BOARD_HAS_PSRAM block (psram_malloc already falls back).
- Keep the runtime psramFound() check only where the buffers are sized for
PSRAM, so a board whose PSRAM failed to init still refuses.
- Size for internal DRAM without PSRAM: 4 KB text buffer and 20 entries per
publish, keeping the pool to a single block and the peak near 13 KB rather
than ~35 KB. Oversized tables truncate and report total_neighbors as before.
Enabled on the ESP32-S3 observer envs (Heltec V3/WSL3, RAK3112, Heltec
Tracker v1.1/v2). Left off for the classic ESP32 T-LoRa V2.1-1.6, which is
already limited to one active TLS slot.
Costs ~7.4 KB static DRAM on repeaters and ~9.6 KB on room servers. The
prefs layout is unchanged, so this is neutral for existing devices.
ArduinoJson v7 hands out document-pool blocks in fixed 4096-byte chunks, so
the pool is not bounded by the size of the text it serialises to. Budgeting
it at NEIGHBORS_JSON_BUFFER_SIZE starved it once the table grew: a 50-entry
table needs 12541 B of pool against the 10240 B cap, and a starved allocator
sets doc.overflowed(), which makes buildNeighborsMessage return 0 and drop
the entire publish rather than truncating the tail.
Repeaters with roughly 40 or more neighbours therefore published no neighbors
message at all, silently, while smaller tables published normally.
Give the pool its own NEIGHBORS_DOC_POOL_BUDGET and add an explicit
NEIGHBORS_MAX_PUBLISH_ENTRIES cap alongside the existing text-size check.
A neighbour heard before the clock is set carries the firmware's unset-clock
default (1715770351, 15 May 2024). Subtracting that from an NTP-synced clock
published ages of ~806 days for neighbours that had just answered a live scope
query, and a backwards clock step reported 0, i.e. "heard just now".
- finishNeighborDiscover() reports the age as unknown ("heard_secs_ago": null)
when the stored stamp and the current clock come from different epochs, or
when the clock has stepped backwards
- handleNeighborDiscoverResponse() re-stamps heard_timestamp on a zero-hop scope
reply, in both the snapshot and the live table, so entries heal once per
discovery cycle instead of waiting for the neighbour's next advert
- publish ordering places usable ages ahead of unknown ones so a poisoned stamp
cannot displace fresh entries when the JSON buffer truncates
- document the null case, and the always-present total_neighbors /
queried_neighbors / truncated fields the payload sample omitted
- add UPSTREAM_BUGS.md, tracking the monotonic-uptime fix to propose upstream
plus the unclamped subtraction in the companion and CLI readouts
Containment only: upstream still stamps neighbours from the wall clock at
packet-reception time, which on a cold boot always precedes NTP.
