三星奥利奥BLE连接问题

Question

我们正在开发Android BLE并成功实施,并且它与所有操作系统版本和设备一起正常运行.

我们可以使用以下代码成功连接:

mBluetoothDevice.connectGatt(this, true, mGattCallback); connectGatt

但最近三星发布了针对三星Galaxy S9,S9 +,S8,S8 +等设备的Android Oreo(8.0.0).现在我们无法使用上述方法使用Android Oreo连接三星设备中的BLE.我们没有得到任何回调mGattCallback.

当autoconnect标志时true,日志是:

06-16 14:03:39.666 13724-13724/com.ble D/BluetoothGatt: cancelOpen() - device: DA:32:19:58:63:69

06-16 14:03:39.797 13724-15182/com.ble D/BluetoothGatt: onClientRegistered() - status=0 clientIf=5

但如果改变autoconnect旗帜,false那么它正在发挥作用.

当我们应用此更改时,当用户超出范围并且再次进入所有设备的范围时,它不会连接.
