I am using CYBLE-012011-00 modules which sends and receives some values over BLE from App.
So while testing with some devices (testing on CySmart app), on some devices it gets disconnected abruptly/services are not discoverable.
On some devices it works fine and does not get disconnected and services are also discovered.
While debugging it was found that on devices on which it disconnects abruptly and unhandled event is called : CYBLE_EVT_GAP_CONNECTION_UPDATE_COMPLETE
And the disconnection error is : CYBLE_HCI_INSTANT_PASSED_ERROR
On devices it works fine, the above two events/error are not generated.
