根據列出的服務here,我試圖訂閱來自Android設備的服務,但無法讓請求部分工作。試圖使用7905F431-B5CE-4E99-A40F-4B1E122D00D0
做廣告,但外圍設備未顯示在iPhone的藍牙設備列表中。還使用(LE)掃描和過濾器發現ANCS服務器,但沒有運氣。任何提示?在Android上訂閱ANCS
編輯:代碼
BleService.java
public void setCharacteristicNotification(BluetoothGattCharacteristic characteristic,
boolean enabled) {
Log.d(TAG, "setCharacteristicNotification");
if (mBluetoothAdapter == null || mBluetoothGatt == null) {

return;
}
mBluetoothGatt.setCharacteristicNotification(characteristic, enabled);
BluetoothGattDescriptor descriptor = characteristic.getDescriptor(UUID.fromString(SampleGattAttributes.DESCRIPTOR));
descriptor.setValue(BluetoothGattDescriptor.ENABLE_NOTIFICATION_VALUE);
mBluetoothGatt.writeDescriptor(descriptor)

更新:我是可以在連接到iPhone上宣傳的服務後找到服務和特徵。但是,在iPhone上收到通知後,訂閱通知不會觸發onCharacteristicChanged
。
update2:全部寫入descriptor.setValue
調用成功,並按順序運行。
UPDATE3:測試設備:從this sample.
UPDATE4代碼的用過那一部分的Nexus 5X的Android 6.0.1; iPhone 6S + iOS版10.3.1
update5:BT記錄
well在Nexus設備上在開發人員選項上,有一個複選框爲「啓用Bluetooth HCI snoop log」。當您啓用它時,設備將記錄藍牙堆棧上發生的所有事情....查看存儲在名爲「HCIsnoop.log」的Sd卡中的日誌。當您的文件放在HD上時,請下載此免費軟件:http://www.fte.com/support/download.aspx?demo=ComProbe%20SD&type=capture&iid=1v查看這些BT日誌文件。有了這個,你可以看到任何已經從一臺設備交換到另一臺設備的數據包(比如BT的Wireshark)。 – PN10
任何你可以在Github上發佈這個應用程序的方式?一個簡單的ANCS安卓客戶端將是驚人的 – Jason
