What is BLE vs Wi-Fi for Android IoT?

BLE excels in low-power, short-range sensor data to Android phones; Wi-Fi for high-bandwidth, internet-direct devices — but drains batteries fast.

Does Android support BLE natively for developers?

Yes, since API 18. Use BluetoothLeScanner for scanning, connectGatt for services — full Kotlin support.

BLE, hands down. Expect months on a coin cell vs. hours on Wi-Fi.
