nRF Connect keeps connecting after closing app

[wibek0508]

I have a BLE device which I can connect to with nRF Connect on Android (v. 9, Samsung Galaxy S8).

After disconnecting in the devices tab, the connection is opened and closed again and again.
If I click disconnect and close the app, the connection keeps opening and closing (shown by the BLE device).
If I open the app later, the devices tab opens again when the connection is made (the connection keeps opening and closing).
If I turn Bluetooth off and back on, the connection keeps opening and closing.

Only after I've put the mobile in airplane mode, the connection is not made again.

I've modified the Blinky app to test communcation with the device. But now I've encountered this problem. I'm still able to connect and send and receive information. It's just this crazy behaviour after disconnecting. Maybe I've done something incorrect, but now the nRF Connect app also shows this behaviour.

I hope anybody have any clue what could cause this behaviour.

Hi Wim, 
Please let me know if that happens again. I suspect that there could be other app causing the issue. Or if the device was running a keyboard profile (which get connected automatically by the phone) earlier.

Hi Hung,

Sorry for this late reply. It's a crazy time afterall.

I'll let you know when this happens again. I don't know what that keyboard profile means. I'll get into that if I run into this issue again.

Regards, Wim
