Ever found your meticulously crafted BLE background scanner abruptly terminating on modern Android versions? You're not alone. Android 10 (API 29) and subsequent releases introduced stringent background execution limits, fundamentally changing how apps can perform long-running tasks, including persistent Bluetooth Low Energy (BLE) scanning. If your IoT solution relies on discovering nearby devices continuously, these OS restrictions become a critical hurdle. This article cuts through the noise, providing a direct, actionable guide to building robust, always-on BLE discovery, even on the latest Android iterations. The Problem: Android's Enforcement on Background Operations Before Android 10, performing background BLE scans was relatively straightforward: start a service, initiate BluetoothLeScanner.startScan() , and process results. Post-Android 10, the landscape changed dramatically.…
