iOS和Android之間的區別藍牙低功耗連接

Question

我有一個BLE外圍設備。我無法使用BluetoothLeGatt示例android應用程序連接到它，並且Android Market中沒有其他BLE應用程序。但iOS BLE應用程序可以連接到它。這是BluetoothLeGatt連接日誌：

07-21 21:06:37.506 27402-27420/bluetoothlegatt D/BluetoothLeScanner: onScanResult() - ScanResult{mDevice=xx:xx:xx:xx:xx:xx, mScanRecord=ScanRecord [mAdvertiseFlags=2, mServiceUuids=null, mManufacturerSpecificData={}, mServiceData={}, mTxPowerLevel=-2147483648, mDeviceName=TestBLE], mRssi=-82, mTimestampNanos=12459248011929}

07-21 21:07:56.060 27402-27421/bluetoothlegatt I/BluetoothLeService: Disconnected from GATT server. 

我應該怎麼做才能連接到此設備？ Android和iOS BLE連接到BLE外圍設備的區別是什麼？

更新： 我的Android設備：

的HTC One M7。 Android版本：5.0.2

LG Nexus 5X。 Android版本：6.0.1

Answer 1

看起來像我找到答案。我們使用CC2564德州儀器芯片。對於這種芯片的Android BluetoothLeGatt示例應用程序BLE連接需要更換這個命令：

mBluetoothGatt = device.connectGatt(this, false, mGattCallback); 

此命令：

mBluetoothGatt = device.connectGatt(this, false, mGattCallback,BluetoothDevice.TRANSPORT_LE); 

Answer 2

07-21 21:07:50.934 27402-27402/bluetoothlegatt D/BluetoothLeService: Trying to create a new connection. 
07-21 21:07:56.060 27402-27421/bluetoothlegatt D/BluetoothGatt: onClientConnectionState() - status=133 clientIf=5 device=xx:xx:xx:xx:xx:xx 
07-21 21:07:56.060 27402-27421/bluetoothlegatt D/BluetoothDevice: mAddress: xx:xx:xx:xx:xx:xx 
07-21 21:07:56.060 27402-27421/bluetoothlegatt I/BluetoothLeService: Disconnected from GATT server. 

發送連接請求後，直到onClientConnectionState，大約有5秒的尋呼時間，我假設它可能是尋呼超時。

很少有查詢： 1）是這個問題也發生在其他Android手機或只是測試手機嗎？ 2）您的設備的廣告時間間隔是多少？

很奇怪，你可以搜索到的設備卻無法連接;或者它應該是您的手機和您的設備之間的RF問題。
