connection terminated under android 6 after 10 seconds

Hello,

I have modified the Android-nRF-Blinky Application to use it with the Datathroughput Demo on the nRF52 DK.

The android application runs on a Nexus 9 with android 6.0.1. I can establish a conneciton and i also can recieve notifications, but after about 10 seconds the connection is lost.

with the mastercontrolpanel i have the same behavioron the tablet..

if i run the application on my sony xperia z3 compact with android 5.1.1 it works fine and also with the mastercontrol panel i have no problems.

here is the log from the android studio..

BluetoothGatt: connect() - device: C5:7F:B0:8E:AA:91, auto: false
BluetoothGatt: registerApp()
BluetoothGatt: registerApp() - UUID=3a9c080d-ae20-47ea-b34c-7ea7798204cc
BluetoothGatt: onClientRegistered() - status=0 clientIf=5
BluetoothGatt: onClientConnectionState() - status=0 clientIf=5 device=C5:7F:B0:8E:AA:91
BluetoothGatt: discoverServices() - device: C5:7F:B0:8E:AA:91
BluetoothGatt: onSearchComplete() = Device=C5:7F:B0:8E:AA:91 Status=0
BluetoothGatt: setCharacteristicNotification() - uuid: 00002a05-0000-1000-8000-00805f9b34fb enable: true
BluetoothGatt: setCharacteristicNotification() - uuid: 00001625-1212-efde-1523-785feabcd123 enable: true
BluetoothGatt: cancelOpen() - device: C5:7F:B0:8E:AA:91
BluetoothGatt: onClientConnectionState() - status=59 clientIf=5 device=C5:7F:B0:8E:AA:91
BluetoothGatt: close()
BluetoothGatt: unregisterApp() - mClientIf=5

It seems that the return of status=59 of onClientConnectionState() closes the connection.. I havent found any information what status=59 mean.

Has somebody already tested the mastercontrolpanel on a device with android 6?

And where i get information about the meaning of "status=59" of onClientConnectionState() .. i couldnt find a reference so far.

    Do you have a nRF51-DK or a nRF51-Dongle? If so, could you use the sniffer to track what is being transferred over the air? The sniffer should be used with Wireshark, and it works best with version 1.10, not one of the newer versions, this answer links to older version of wireshark.
