Notification stopped after onClientConnParamsChanged() in Android

Hello Dialog,
我use Android to communicate with the DA14580 platform. The DA14580 is programmed to send notifications to the phone, however, when the connection parameter changed, the notification stopped even though the connection state is still 0:

D/BluetoothGatt: onClientConnParamsChanged() - Device=80:EA:CA:00:00:03 interval=39 status=0
D/BluetoothAdapter: STATE_ON
D/BluetoothAdapter: STATE_ON
D/BluetoothLeScanner: could not find callback wrapper
D/BluetoothGatt: onClientConnParamsChanged() - Device=80:EA:CA:00:00:03 interval=480 status=0
……

Previously, I worked around this by sending a command to the DA14580 again to restart the notification, but I'd like to solve it completely. I didn't find the handler for onClientConnParamsChanged() or related solutions. On stackoverflow, there is a post pretty the same with my scenario but no answers available.(https://stackoverflow.com/questions/43925466/bluetoothgatt-onclientconnp...) Could you please help? Thanks.

Hi sentimental,

Hi sentimental,

我dont see anything like this on the 580 side, even when i enable the notifications and the parameter update arrives afterwards the CCC for the characteristic retains its value right after message, so i suppose that this is related to the implementation on the phone side, so since this is something related to the android or the iOS application this question is off topic for this forum.

Thanks MT_dialog
