The CALIBRATE_ALL (0x7F) command inside resetAGC() clears bit 0 of the
undocumented 0x8B5 register. That bit is set once in init() by #9571 and
#9777 to improve SX1262 RX sensitivity, and the AGC-reset path was not
re-applying it. Result: every SX1262 node silently loses the RX
sensitivity patch ~60s after boot and never recovers until reboot.
Empirically confirmed on Heltec Mesh Node T114 (nRF52840 + SX1262):
- Post-calibration read of 0x8B5 = 0x04 (bit 0 cleared)
- After re-apply: 0x05 (bit 0 set)
Reproducible every AGC_RESET_INTERVAL_MS tick.
Fix re-applies the register bit alongside the existing post-calibration
re-applies (setDio2AsRfSwitch, setRxBoostedGainMode).

* fix(native): implement BinarySemaphorePosix with proper pthread synchronization
The BinarySemaphorePosix class (used on all Linux/portduino/native builds)
had stub implementations: give() was a no-op and take() just called
delay(msec) and returned false. This broke the cooperative thread scheduler
on native platforms — threads could not wake the main loop, radio RX
interrupts were missed, and telemetry never transmitted over the mesh.
Replace the stubs with a proper binary semaphore using pthread_mutex_t +
pthread_cond_t + bool signaled:
- take(msec): pthread_cond_timedwait with CLOCK_REALTIME timeout, consumes
signal atomically (binary semaphore semantics)
- give(): sets signaled=true, signals condition variable
- giveFromISR(): delegates to give(), sets pxHigherPriorityTaskWoken
Tested on Raspberry Pi 3 Model B (ARM64, Debian Bookworm) with Adafruit
LoRa Radio Bonnet (SX1276). Before fix: no radio TX/RX, no telemetry on
mesh. After fix: bidirectional LoRa, MQTT gateway, telemetry all working.

The W5100S Ethernet chip has only 4 hardware sockets. On RAK4631
Ethernet gateways with syslog and NTP enabled, all 4 sockets were
permanently consumed (NTP UDP + Syslog UDP + TCP API listener + TCP
API client), leaving none for MQTT, DHCP lease renewal, or additional
TCP connections.
- NTP: Remove permanent timeClient.begin() at startup; NTPClient::update()
auto-initializes when needed. Add timeClient.end() after each query to
release the UDP socket immediately.
- Syslog: Remove socket allocation from Syslog::enable(). Open and close
the UDP socket on-demand in _sendLog() around each message send.
- MQTT: Fix socket leak in isValidConfig() where a successful test
connection was never closed (PubSubClient destructor does not call
disconnect). Add explicit pubSub->disconnect() before returning.

* fix: MQTT settings silently fail to persist when broker is unreachable
isValidConfig() was testing broker connectivity via connectPubSub() as
part of config validation. When the broker was unreachable (network not
ready, DNS failure, server down), the function returned false, causing
AdminModule to skip saving settings entirely — silently.
This removes the connectivity test from isValidConfig(), which now only
validates configuration correctness (TLS support, default server port).
Connectivity is handled by the MQTT module's existing reconnect loop.
Fixes#9107
* Add client warning notification when MQTT broker is unreachable
Per maintainer feedback: instead of silently saving when the broker
can't be reached, send a WARNING notification to the client saying
"MQTT settings saved, but could not reach the MQTT server."
Settings still always persist regardless of connectivity — the core
fix from the previous commit is preserved. The notification is purely
advisory so users know to double-check their server address and
credentials if the connection test fails.
When the network is not available at all, the connectivity check is
skipped entirely with a log message.
* Address Copilot review feedback
- Fix warning message wording: "Settings will be saved" instead of
"Settings saved" (notification fires before AdminModule persists)
- Add null check on clientNotificationPool.allocZeroed() to prevent
crash if pool is exhausted (matches AdminModule::sendWarning pattern)
- Fix test comments to accurately describe conditional connectivity
check behavior and IS_RUNNING_TESTS compile-out
* Remove connectivity check from isValidConfig entirely
Reverts the advisory connectivity check added in the previous commit.
While the intent was to warn users about unreachable brokers,
connectPubSub() mutates the isConnected state of the running MQTT
module and performs synchronous network operations that can block
the config-save path.
The cleanest approach: isValidConfig() validates config correctness
only (TLS support, default server port). The MQTT reconnect loop
handles connectivity after settings are persisted and the device
reboots. If the broker is unreachable, the user will see it in the
MQTT connection status — no special notification needed.
This returns to the simpler design from the first commit, which was
tested on hardware and confirmed working.
* Use lightweight TCP check instead of connectPubSub for validation
Per maintainer feedback: users need connectivity feedback, but
connectPubSub() mutates the module's isConnected state.
This uses a standalone MQTTClient TCP connection test that:
- Checks if the server IP/port is reachable
- Sends a WARNING notification if unreachable
- Does NOT establish an MQTT session or mutate any module state
- Does NOT block saving — isValidConfig always returns true
The TCP test client is created locally, used, and destroyed within
the function scope. No side effects on the running MQTT module.

* Fix for preserving pki_encrypted and public_key when relaying UDP multicast packets to radio.
PKI DMs sent over UDP multicast had their pki_encrypted flag and public_key fields explicitly cleared before being forwarded to the LoRa radio. This caused the receiving node to treat the packet as a channel-encrypted message it couldn't decrypt, silently dropping it.
The MQTT ingress path correctly preserves these fields. The UDP multicast ingress path should behave the same way.

Zeroize MeshPacket before decoding to prevent data leakage.

* Fix RAK4631 Ethernet gateway API connection loss after W5100S brownout
PoE power instability can brownout the W5100S while the nRF52 MCU keeps
running, causing all chip registers (MAC, IP, sockets) to revert to
defaults. The firmware had no mechanism to detect or recover from this.
Changes:
- Detect W5100S chip reset by periodically verifying MAC address register
in reconnectETH(); on mismatch, perform full hardware reset and
re-initialize Ethernet interface and services
- Add deInitApiServer() for clean API server teardown during recovery
- Add ~APIServerPort destructor to prevent memory leaks
- Switch nRF52 from EthernetServer::available() to accept() to prevent
the same connected client from being repeatedly re-reported
- Add proactive dead-connection cleanup in APIServerPort::runOnce()
- Add 15-minute TCP idle timeout to close half-open connections that
consume limited W5100S hardware sockets

* Stop UDP multicast handler during W5100S brownout recovery
After a W5100S chip brownout, the udpHandler isRunning flag stays
true while the underlying socket is dead. Without calling stop(),
the subsequent start() no-ops and multicast is silently broken
after recovery.
Made-with: Cursor
* Address Copilot review: recovery flags and timeout constant
Move ethStartupComplete and ntp_renew reset to immediately after
service teardown, before Ethernet.begin(). Previously, if DHCP
failed the early return left ethStartupComplete=true, preventing
service re-initialization on subsequent retries.
Replace #define TCP_IDLE_TIMEOUT_MS with static constexpr uint32_t
for type safety and better C++ practice.
