Sorted out all the sample apk and source code downloads and videos of Android Bluetooth 2.0SSP and 4.0 BLE. The video guarantees that it can send and receive hexadecimal or characters. It can automatically connect to the paired device and communicate with the serial port module . 100 copies of the unpublished source code.
Note: 20190507 about the cause and solution of the Bluetooth SSP2.0 device module cannot be found in android 6.0 and subsequent systems
Before version 6.0, to use the Bluetooth function, you only need to configure the following permissions:
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
6.0 and later versions, using Bluetooth scanning, you also need to add the following permissions, and the permissions need to be dynamically applied during use:
<!-- Only needed for Android 6.0 Bluetooth scan -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
or
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
So to use the Bluetooth SSP2.0 device module, a total of 3 permissions are required:
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
(Do not refuse when the APP prompts permission to open Bluetooth and positioning permissions)
