When I connect ble after I try to open the notification, but often return BleGattException status = 133, sometimes it will sometimes not .

this is my code :

    mConnectingDevice.establishConnection(false)
   .doOnNext(this::storeConnect)
   .flatMap(rxBleConnection -> rxBleConnection.setupNotification(notifyUuid))
   .observeOn(AndroidSchedulers.mainThread())
   .flatMap(notificationObservable -> notificationObservable)
   .observeOn(AndroidSchedulers.mainThread())
   .subscribe(this::onNotify, this::connectFail);

connectFail return BleGattException status = 133

This is the print log // behind my comments：

  • This seems to be an Android BLE Stack issue on a lower level. Have you checked the HCI snoop log? What phone do you use? What peripheral? – Dariusz Seweryn Aug 28 '17 at 14:33
  • Intelligent device Bluetooth module is nordic, I used Huawei and xiaomi are such a phenomenon, I now practice in the doOnUububscribe () method to re-connect, the problem is certainly there @DariuszSeweryn – Jeong Woo Sep 09 '17 at 02:18

Please using nRF connect app for test your device: https://play.google.com/store/apps/details?id=no.nordicsemi.android.mcp

If the app can be connect to your device, I think issue of rxble lib.

  • nRF connection device is normal, and disconnect again after the connection will not appear 133, I have submitted the issue on rxble, but they think this is question not issue, to the closed. – Jeong Woo Sep 09 '17 at 02:07
