* Protobufs
* Wire up MEDIUM_TURBO modem preset
MEDIUM_TURBO (500 kHz, SF9, CR 4/5) already existed in the protobuf enum but
was never wired into firmware, so selecting it silently fell through to the
LONG_FAST default and rendered an "Invalid" display name.
Add its bw/sf/cr mapping (modemPresetToParams), display name (MediumTurbo/MedT),
PRESETS_STD membership (standard regions only — 500 kHz does not fit EU868's
250 kHz band, so it stays out of PRESETS_EU_868 and is rejected/clamped there),
and the MEDIUM SNR-grading bucket. Includes positive coverage in test_radio,
EU868-reject + US-accept coverage in test_admin_radio and test_mesh_beacon,
the STD preset count 9->10, an extended fuzz range, and the client-spec doc.
* Address review feedback on MEDIUM_TURBO tests
- test_mesh_beacon: assert has_mesh_beacon before checking the invalid preset was
cleared, so the EU868-cleared test can't pass on a dropped message (matches the
existing SHORT_TURBO test).
- test_fuzz_packets: draw modem presets from _ModemPreset_ARRAYSIZE instead of a
hard-coded 17 so the fuzz range tracks future enum additions automatically.
* Add software LoRa IRQ polling and an MCP23017 expander HAL for radios behind an I2C expander
Some boards route the SX126x control lines (NRESET/DIO1/BUSY) through an I2C
GPIO expander instead of native GPIOs, and don't wire the expander's /INT to
the MCU, so RadioLib cannot take a hardware DIO1 interrupt.
Two reusable pieces, both gated behind USE_MCP23017 / LORA_DIO1_SOFTWARE_POLL
so builds that don't define them are unaffected:
- ExtensionIOMCP23017 + MCP23017LockingArduinoHal: a RadioLib HAL that maps
virtual pins (MCP23017_VPIN_BASE .. +15) onto an MCP23017's GPIO, so
RESET/BUSY/DIO1 reads and writes become I2C transactions while the real SPI
GPIOs (SCK/MOSI/MISO/CS) pass straight through. A failed I2C read skips the
read-modify-write rather than clobbering the rest of the bank.
- LORA_DIO1_SOFTWARE_POLL: with no DIO1 interrupt available, the SX126x
interface polls the radio IRQ status register from the radio thread and
synthesizes the ISR_TX/ISR_RX events, filtering noisy preamble/header IRQs so
they can't starve TX. A 1 ms ISR_POLL_TICK drives the poll; TX timers may
overwrite the pending tick (pollMissedIrqs() is the backup that bounds the
latency of the busy-Rx contention window). Behaviour is unchanged on all
boards that keep the hardware interrupt.
* Add Meshnology W10 AIOT Dev Kit variant (SX1262 via MCP23017 expander)
ESP32-S3R8 + EBYTE E22-900MM22S (SX1262) + AXP2101 PMIC + Quectel L76KB GPS +
SPI TFT, with the radio's RESET/DIO1/BUSY and the LCD reset routed through an
MCP23017 I2C expander at 0x20. The expander's /INT is not wired to the ESP32,
so DIO1 uses the software poll. Pins come from the board schematic and the
vendor firmware; the expander is an MCP23017 despite the V1.1 schematic's stale
'TCA9555' label (the V1.2 placement diagram and all vendor code use the MCP23017
register map).
A local pins_arduino.h shadows the generic esp32s3 variant to drop RGB_BUILTIN,
which otherwise pulls the Arduino RMT HAL into the link and fails against this
build's trimmed FreeRTOS config.
Reports HardwareModel 140 (MESHNOLOGY_W10, already present in the protobufs).
Hardware-verified on a real W10 AIOT Dev Kit: AXP2101 PMU, MCP23017, SX1262
init + a full over-the-air TX/RX round trip through the expander, PCF85063 RTC,
SHT41 and QMI8658 auto-detected, and an L76KB GPS fix.
* meshnology-w10: enable ES8311 speaker for notification tones
Bring up the ES8311 codec (I2C 0x18) -> NS4150 amp -> speaker so the board can
play notification tones / ringtones over the I2S buzzer path (the
use_i2s_as_buzzer external-notification option). Codec2 voice stays out of
scope: it is SX1280-only and this is a sub-GHz board.
- variant.h: HAS_I2S + DAC_I2S pins (MCLK=1, BCK=2, WS=4, DOUT=5, DIN=3)
- platformio.ini: arduino-audio-driver + ESP8266Audio + ESP8266SAM
- extra_variants/meshnology_w10/variant.cpp: lateInitVariant() configures the
ES8311, mirroring the other Meshtastic ES8311 boards. Kept codec-only (no
main.h) so the audio driver's 'using namespace audio_driver' does not pull a
conflicting GpioPin into scope alongside Meshtastic's class GpioPin.
- AudioThread.h: toggle the NS4150 amp (MCP23017 EXIO_PA_CTRL) around playback.
Verified on hardware: a test tune played audibly through the speaker.
* meshnology-w10: address review feedback on the MCP23017 driver
- ExtensionIOMCP23017: serialize register access with a mutex, since the radio
HAL (BUSY/DIO1/RESET) and AudioThread (amp enable) now reach the expander from
different threads and the read-modify-write paths are not atomic.
- digitalRead: return a fail-safe HIGH on a failed read instead of LOW, so a
transient I2C error on the LoRa BUSY line can't look like 'ready' and let
RadioLib start an SPI transaction early. (DIO1 is polled via the radio IRQ
register, not this pin.)
- enablePinChangeInterrupt: use the checked readReg() overload and skip on a
failed read, matching the other read-modify-write helpers.
- meshnology_w10 variant.cpp: log a warning if an ES8311 register write NACKs
instead of silently leaving the codec half-configured.
- RadioInterface.cpp: guard the MCP23017 HAL branch with ARCH_ESP32 to match the
include and driver-file guards.
* Replace board-model audio/sleep ifdefs with reusable variant capability macros
Two shared-code spots keyed off specific hardware models; move the board-specific
detail into opt-in macros the variants define, so the core code stays generic and
new boards can opt into the behavior class without touching shared files.
- AudioThread amp control: drop the T_LORA_PAGER / MESHNOLOGY_W10 ifdefs. A board
with an I2S amp now defines AUDIO_AMP_ENABLE(on) in its variant.h (T-LoRa Pager
and Meshnology W10 do), and AudioThread just calls it around playback. The
expander includes are keyed on USE_XL9555 / USE_MCP23017 (capabilities) instead
of the model name.
- Light-sleep / DIO1 wakeup: drop the SENSECAP_INDICATOR check. Boards whose
LORA_DIO1 is an expander pin (not an ESP32 GPIO) define LORA_DIO1_EXTENDED_IO
(SenseCAP Indicator and Meshnology W10), and sleep.cpp keys off that for both
the light-sleep skip and the DIO1 GPIO-wakeup skip. This also fixes a latent
issue on the SenseCAP: it previously reached the GPIO-wakeup path and called
gpio_pulldown_en() on a virtual expander pin; it now skips that cleanly.
Builds verified on meshnology_w10, tlora-pager, and seeed-sensecap-indicator.
* meshnology-w10: silence cppcheck constParameterPointer on the ISR-callback helper
isIsrTxCallback() takes a function pointer it only compares; cppcheck's
constParameterPointer wants it 'pointer to const', which is meaningless for a
function pointer (the codebase already globally suppresses the sibling
constParameterCallback). Inline-suppress it to keep the check green.
* HopScaling: qualify the member assignment as this->count
cppcheck (CI's version) flags 'count = newCount;' at the end of trimIfNeeded()
as uselessAssignmentArg ('assignment of function parameter has no effect') - a
false positive, since count is a member that outlives the call. Write it as
this->count (matching the Step-1 assignment above) so the analyzer sees a member
write. This finding comes in via the develop merge, not this board; fixing it
here to unblock the PR's cppcheck check.
* first pass tests
* more tests
* Fix two crafted-admin-packet crashes found by the E5 fuzzer
Both are reachable from an authorized admin (local from==0, admin channel,
or PKC) - remote DoS:
1. SIGFPE in LoRa config validation. A set_config LoRaConfig with
use_preset=false and bandwidth=0 makes freqSlotWidth 0, so numFreqSlots
is 0 and `hash(name) % numFreqSlots` (RadioInterface.cpp) divides by
zero. Guard the modulo; the existing channel_num check then rejects/
clamps the config.
2. Stack overflow in Channels::getKey. A SECONDARY channel at the primary
slot with an empty PSK recursed into getKey(primaryIndex) forever. Skip
the primary-key borrow when chIndex == primaryIndex.
Re-enable the E5 admin fuzzer to hit both triggers again (use_preset both
ways incl. bandwidth 0, plus the set_channel tag) as regression guards.

* Correct fuzz-test invariants after the crash fixes
- E5 admin fuzz: node eviction under a filling NodeDB is legitimate, so
assert only the bounded-count invariant, not that a specific seed node
survives 6000 mutating ops.
- TMM blitz: scope off the nodeinfo direct-response send path (it needs a
fully-wired MeshService/phone queue the fixture doesn't provide; the
deterministic directResponse tests cover it). The crafted-nodenum
rate/unknown/position cache stress is unchanged.
clod helped too
* realistic tests
* test: dedup fuzz RNG into shared test/support/DeterministicRng.h
The four in-tree fuzz suites (test_fuzz_decode, test_fuzz_packets,
test_hop_scaling, test_traffic_management) each carried a byte-identical
copy of the seeded 64-bit LCG (rngSeed/rngNext/rngByte/rngRange). Hoist
it into one shared header so there is a single generator to reason about
and no risk of the copies drifting. static inline keeps per-suite state
per translation unit and avoids -Wunused-function for suites that don't
use every helper. Also corrects a stale comment in test_traffic_management
(the blitz's nodeinfo direct-response path is intentionally left off).
No behavioral change: same constants, same per-suite seeds.
clod helped too
* test: fuzz uncovered ProtobufModule handlers and the MQTT downlink ingress
Extend the in-tree fuzz coverage to packet sources that previously had
none:
- test_fuzz_packets E8/E9/E10: drive PositionModule, DeviceTelemetryModule
and NeighborInfoModule at handleReceivedProtobuf directly (via using-shims,
bypassing the ProtobufModule reply/send path so no router is needed). The
fixture already stands up nodeDB/service/channels, and nodeStatus/powerStatus
are auto-initialized in main.cpp, so no new globals are required. Adds a
shared fuzzRxHeader() helper for crafting adversarial RX packet headers.
- test_fuzz_decode: add meshtastic_KeyVerification to the decode table. The
KeyVerification and StoreForward handler paths are documented as decode-level
only, with the concrete reason each is intrinsic (private-state gating /
PSRAM + self-pointer wiring), not a fixture gap.
- test_mqtt: test_receiveFuzzServiceEnvelope blitzes the non-RF broker-push
ingress (onReceiveProto) two ways - raw garbage bytes that must fail envelope
decode cleanly, and a well-formed ServiceEnvelope wrapping a crafted inner
MeshPacket over crafted channel_id/gateway_id - exercising the channel match,
isFromUs, XEdDSA receive policy and perhapsDecode chain. Adds a deliverRaw()
passthrough to MQTTUnitTest.
All under the coverage env (ASan/LSan). No firmware/src changes. Full sweep
GREEN 27/27, 544 cases.

* Harden LoRa/channel config against crafted admin messages; consolidate test helpers
Production (review findings on the hot-fuzz crash fixes):
- Clamp bandwidth at the source (clampBandwidthKHz) in checkOrClampConfigLora
and applyModemConfig so numFreqSlots can never be 0 for any consumer; a
bandwidth-0 set_config previously passed validation and re-armed the SIGFPE
on the next applyModemConfig.
- Guard applyModemConfig's hash % numFreqSlots (the validator's sibling modulo
was fixed earlier but this one was still unguarded).
- Enforce the primary-channel invariant in Channels::onConfigChanged: a config
demoting every slot now re-promotes the stale SECONDARY slot (keeping its
key) or restores the default channel if the slot is DISABLED, instead of
leaving every getPrimaryIndex() reader on a non-primary slot. The getKey
recursion guard stays as defense-in-depth.
Tests:
- New test/support/MockMeshService.h and AdminModuleTestShim.h replace four
byte-identical mocks and three divergent admin shims (test_mqtt's capturing
mock is genuinely different and stays).
- DeterministicRng.h: add rngFill() (replaces 14 hand-rolled fill loops) and
rngEdgeNodeNum() (unifies the three NodeNum boundary pools).
- Extract fuzzChannelSettings() shared by the set_channel case and fuzzBeacon.
- fuzzBeacon: the un-terminated branch now fills the whole buffer with non-NUL
bytes so the strnlen bound is actually stressed (~50% of iterations, not ~4%).
- E6 beacon fuzz: replace the TEST_ASSERT_TRUE(true) tautology with real
invariants (handler never consumes; offers land in lastReceivedOffer keyed
to the sender).
- Trim the seven over-long comment blocks flagged against the 1-2 line rule;
the FINDINGS trailer moves to this commit message (see production notes).

* Clamp UTF-8 char length in the emote walkers; add test_fuzz_emotes
A TEXT_MESSAGE payload is opaque protobuf bytes, so PB_VALIDATE_UTF8 never
screens it - invalid UTF-8 and truncated multi-byte lead bytes reach the
emote/width render path verbatim. EmoteRenderer's walkers advanced by
utf8CharLen(lead) without clamping to the bytes actually remaining, so a
truncated lead (e.g. a lone 0xF0, which claims 4 bytes) near the end of the
buffer made getUtf8ChunkWidth's memcpy read past the string. ASan confirms a
heap-buffer-overflow READ from measureStringWithEmotes.
Add utf8CharLenClamped() and use it at every walk site (width measure,
truncation cut-loop, and the draw-path text-run/chunk builders); the one
already-guarded site (matchAtIgnoringModifiers) is unchanged.
New test/test_fuzz_emotes drives measureStringWithEmotes and truncateToWidth
over adversarial byte strings (biased to embed/end in truncated multi-byte
leads) in exact-sized heap buffers so any over-read is a hard ASan fault. Its
headless display uses a synthetic font (firstChar 0, fontData centered in a
large buffer) so the stock OLEDDisplay::getStringWidth - which indexes the
font jump table with a signed char and over-reads for any byte >= 0x80 - does
not mask the finding. native-suite-count bumped 27 -> 28.
Full native suite GREEN 28/28 under the coverage (ASan/LSan) env.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* Keep emote width measurement in-bounds for non-ASCII bytes
OLEDDisplay::getStringWidth (the utf8=false path EmoteRenderer uses on default
builds) indexes the font jump table by (c - firstChar) with a signed char and
no bounds check, so any byte outside printable ASCII - high bytes from UTF-8
text, but also a stray control byte like 0x0A - reads outside the font array.
On-device this reads adjacent flash and returns a garbage width; under ASan the
test_fuzz_emotes fuzzer flags it as a global-buffer-overflow, and it made the
non-ASCII width measurement meaningless either way.
The OLED driver is a pinned upstream dependency, so guard it firmware-side in
EmoteRenderer's getStringWidth helper: measure a sanitized copy where any byte
outside [0x20, 0x7E] counts as a '?' placeholder. Printable ASCII is unchanged
and the UA/RU lookup path is untouched.
test_fuzz_emotes now drives a real ArialMT font instead of the synthetic
in-bounds font it needed before this fix, so the suite exercises the true
production width path (utf8CharLen clamp + this sanitizer) end to end. The same
fuzzer tripped the global-buffer-overflow before this change.
Full native suite GREEN 28/28 under the coverage (ASan/LSan) env.

I thought git would be smart enough to understand all the whitespace changes but even with all the flags I know to make it ignore theses it still blows up if there are identical changes on both sides.
I have a solution but it require creating a new commit at the merge base for each conflicting PR and merging it into develop.
I don't think blowing up all PRs is worth for now, maybe if we can coordinate this for V3 let's say.
This reverts commit 0d11331d18.
KZ_863 was set to wide_lora = true. This was a mistake, induced because the
regulations would allow SHORT_TURBO. However, that interpretation of the code
was incorrect and wide_lora has a different meaning.

Ham Mode ignores region regulatory limits, so regardless of whether
we set a single TX_GAIN_LORA or an array with a non-linear PA,
we shouldn't limit the power.
Co-authored-by: Ben Meadors <benmmeadors@gmail.com>
* Introduce non-linear TX_GAIN_LORA
Previously, our TX_GAIN_LORA setting was a single number, intended
to represent the signal gain going through a power amp (plus or minus
antenna, attenuator, and other parts of the RF chain).
It turns out the relationship between the input power (i.e. from an SX1262)
and total output power is often non-linear. While we fudged a 1dBm difference
here and there with existing chips, the Heltec v4 has a 5dBm difference in gain
depending on which end of the input power (and frequency) you are at.
To allow people to run their Heltec v4 at max power when legal, and future
proof our code, this patch introduced an optional array-based TX_GAIN_LORA.
Define NUM_PA_POINTS and set TX_GAIN_LORA to gain values for a given input
power in 1dBm increments, and all will work.
For linear systems, just continue to define TX_GAIN_LORA as a number.
Fixes https://github.com/meshtastic/firmware/issues/8070
* Remove temporary power limit on heltec v4
* Add function RadioLibInterface::checkOutputPower
* Ensure SX126x reaches minimum supported power.
* Keep it simple, instead.
