The real Arduino.h includes stdlib.h, so ConfigSerializer.cpp reaches atoi,
atol and atof through it and compiles on device. The mock supplied only
cstdint, cmath and Stream.h, leaving those undeclared — and since the native
env compiles ConfigSerializer.cpp into every suite via build_src_filter, all
21 suites errored rather than just its own.
Fixing the mock keeps src/ identical to upstream and covers any other source
relying on the same transitive include.
pio test -e native: 297 test cases, 297 succeeded.
The rolling-release body is what the flasher dropdown serves as changelog.
Drop the stale v1.16.0 experimental blurb and describe the current observer
surface: MeshCore 1.17.1, web config, in-channel OTA, and neighbors.
Both channels move together so a node comparing its embedded base against
its own channel's manifest does not read as permanently behind.
Resets the per-base build counter to N=1 on both channels. Nodes still on
v1.17.0.N take the diff_base branch in ESP32Board's OTA comparison, so the
counter going backwards does not strand them.
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.
SPI pins that are set to -1 cause OOB reads on NRF52. The unused Serial2 pin definitions were removed to avoid potential issues with the Uart framework.
Setting SPI pins to values that are OOB of the g_ADigitalPinMap[] array causes OOB reads. This variant.h has pin 0 as 0xFF which passes through as NRFX_SPIM_PIN_NOT_USED.
Documents why the largest allocatable block on a non-PSRAM observer walks down in
16 KiB steps at every TLS reconnect, and what to do about it.
The framework builds mbedTLS with the symmetric buffer configuration
(CONFIG_MBEDTLS_SSL_MAX_CONTENT_LEN 16384), so each broker slot holds two 16 KiB
record buffers in internal DRAM and two slots cost 64 KiB on a board with about
80 KiB free. Confirmed against the sdkconfig the Heltec env actually links, not
the IDF 5.3 libs package that belongs to the esp32c6 env.
Rebuilding only the mbedTLS archives with an asymmetric outbound buffer of 4 KiB
is ABI-safe, because in_buf/out_buf are heap pointers sized in ssl_setup() and no
public struct embeds a CONTENT_LEN-sized array. Dropping KEEP_PEER_CERTIFICATE is
not, since it changes mbedtls_ssl_session layout, so it is excluded.
Also records two traps worth not rediscovering: esp32-arduino-lib-builder's
release/v4.4 clones its dependencies at master and no longer resolves, and
pointing platform_packages at a file:// framework copy overwrites the shared
package for every other project on the machine.
Introduced consistent preferences for external LoRa FEM RX and TX gain settings in NodePrefs. Updated companion MyMesh to apply these settings during initialization and transmission. Added unit tests to verify the round-trip serialization of these new preferences.
Nine commits reducing the MQTT bridge's internal-DRAM footprint, plus four
fixes that rode with them (invalid path encodings, stale-JWT scan after a
clock correction, setup-retry interval measured from the failure, retried
setup consuming the reconnect allowance).
Touches no prefs surface -- nothing in NodePrefs, MQTTPrefs, or
ConfigSerializer -- so /prefs.json layout is unaffected and there is no
fleet config risk.
Soak evidence: every soak branch already contained this work in full. Device 1
has run it 69.6 h with 325,852 publishes, 0 errors and 0 reboots. The caveat
worth carrying: that long-duration evidence is all on the reduced-TLS
framework (OUT_CONTENT_LEN 4096). Device 3 is now soaking it on the stock
framework, which is where the allocation-ordering interaction with the full
16 KiB record buffers actually gets exercised.
Both channels move together: the beta workflow's FIRMWARE_VERSION must equal
production's, since a node compares its embedded base against its own channel's
manifest and a mismatch would read as permanently behind.
Resets the per-base build counter to N=1 on both channels. Nodes still on
v1.16.0.N take the diff_base branch in ESP32Board's OTA comparison ('different
base version is always an update'), so the counter going backwards does not
strand them; the build-number arithmetic only runs when the base matches.
The flasher repo's config.json version key still needs the matching bump.
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.
