获取辅助蓝牙gatt服务android

Question

Fetch android secondary bluetooth gatt service from bluetooth android API's.

Currently below is the code where we fetch ble services :

public void onServicesDiscovered(BluetoothGatt gatt, int status) {
            if (status == BluetoothGatt.GATT_SUCCESS) {
                broadcastUpdate(ACTION_GATT_SERVICES_DISCOVERED);
                List<BluetoothGattService> gattServices = mBluetoothGatt.getServices();
                Log.e("onServicesDiscovered", "Services count: "+gattServices.size());

                BluetoothGattService bleServ = mBluetoothGatt.getService(UUID.fromString("22222222-0000-0000-0000-000000000000"));

                for (BluetoothGattService gattService : gattServices) {
                    String serviceUUID = gattService.getUuid().toString();
                    Log.e("onServicesDiscovered", "Service uuid "+serviceUUID);
                }
            } else {
                Log.w(TAG, "onServicesDiscovered received: " + status);
            }
        }

Even tried fetching exclusively the secondary service but it returns null object :

 BluetoothGattService bleServ = mBluetoothGatt.getService(UUID.fromString("22222222-0000-0000-0000-000000000000"));

Can someone point any pointers how to search secondary ble service in Android.

您应该使用以下方法：在主要服务上使用https://developer.android.com/reference/android/bluetooth/BluetoothGattService.html#getIncludedServices（） 。
