NimBLE-Arduino 1.4.2 had an init/fire race in its FreeRTOS callout porting layer where os_callout_timer_cb dispatched a queued TimerHandle expiry against a not-yet-initialized event (NULL fn pointer), causing PC=0 InstrFetchProhibited within ~1s of boot when the camera task starved the timer service. Confirmed by ets_printf instrumentation. Upgrading to ^2.0.0 rewrites the porting layer and eliminates the race; verified clean on the customer network for 1+ hour. Also rolls in DNS-resilience work that surfaced the BLE crash during provisioning: pin lwIP/esp-netif resolvers to 1.1.1.1/8.8.8.8 across DHCP renewals, add three-tier resolver fallback in reporter with a hardcoded IP of last resort, and switch to raw WiFiClient with manual Host header to bypass HTTPClient's brittle DNS path. Migration touches for NimBLE 2.x: - NimBLEAdvertisedDeviceCallbacks -> NimBLEScanCallbacks - onResult signature now takes const NimBLEAdvertisedDevice* - setAdvertisedDeviceCallbacks -> setScanCallbacks - start(0, nullptr, false) -> start(0, false, false) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
