BleGattException status return 133

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 , i set it after 500 ms open notify:

mConnectingDevice.establishConnection(false)
                    .doOnNext(this::storeConnect)
                    .delay(500, TimeUnit.MILLISECONDS)
                    .flatMap(rxBleConnection -> rxBleConnection.setupNotification(notifyUuid))
                    .observeOn(AndroidSchedulers.mainThread())
                    .flatMap(notificationObservable -> notificationObservable)
                    .observeOn(AndroidSchedulers.mainThread())
                    .subscribe(this::onNotify, this::connectFail); 

connectFail return BleGattException status = 133

Hey!

Thank you for contacting us. This seams to be a general question rather than an issue. Please ask on stackoverflow.com and add tag rxandroidble

@evansherry the status=133 is a generic GATT_ERROR message. It is caused mostly by how the BLE stack works internally on your phone. The issue is most probably related to how your peripheral—phone pair works. If you would like to have more information you would need to get detailed HCI logs from a Xiaomi/Huawei device that shows the problem and another from a phone that works fine.
