The u-blox Bluetooth low energy Android app allows developers to evaluate the stand-alone Bluetooth low energy modules from u-blox.
These files are all working with Android Studio 4.2.2 and with SDK version 29 (Android 10).
Needed files to get Bluetooth low energy working in your app:
\services\BluetoothLeService.java
\utils\BLEQueue.java
\utils\GattAttributes.java
\utils\QueueItem.java
In the app manifest you need at least the following:
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-feature android:name="android.hardware.bluetooth_le" android:required="true" />For a simple and stripped down Activity see BasicBLEActivity.java, here we have the simplest way of connecting to the service to be able to connect, read, write and to get notifications from a Bluetooth low energy device like NINA-B1. This Activity is well documented to get you started in no time.
