Keeping Up Continuous Development of BLE-Based Apps
summary
Demonstrates wrapping callback-heavy Android BLE (dozens of callbacks) into Kotlin Coroutines and Flow so code matches the device protocol steps: connect, await connected, discover services, await discovery, enable notifications (including writing the CCC descriptor), await notifications, and read/write characteristics. Presents a Bluetooth client implemented with MutableStateFlow and suspend/await helpers, discusses flaky issues like error 133 and silent Bluetooth stacks, and recommends toggling Bluetooth or restarting the device and capturing logs with Bugfender for debugging.
