Root cause: react-native-ble-plx v3.5.0 calls Promise.reject(null, ...) in 17 places in BlePlxModule.java, causing NullPointerException when BLE operations fail (e.g., device disconnect during WiFi config). Fixes applied: - patch-package: Replace all safePromise.reject(null, ...) with safePromise.reject(error.errorCode.name(), ...) in native Java code - Lazy BLE initialization: Defer BleManager creation until first use - Safe error handling: Add transactionId and safeReject wrapper Reference: https://github.com/dotintent/react-native-ble-plx/issues/1303 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
