This article demonstrates how to use the Serial Device Manager (SDM) to send information from Android‘s built-in NFC reader to the cursor location.
1. Navigate to the Serial Device Manager (SDM).
2. Tap on the options menu button (the three vertical dots button at the top right-hand corner of the SDM view).
3. Select Connect BLE via NFC chip.
This brings you to the NFC Connect view (see image below).
4. Place the NFC chip beneath the Android device’s NFC sensor. The SDM will use the data on the NFC chip to immediately pair with the scanner (no Bluetooth discovery necessary).
