BLE disconnect every 30sec depending of the PC since Windows update

[Sebastien]

Our BLE HID mouse devices has work well during several months and since some windows update, on some PC, the BLE is disconencted every 30 sec.

We received a BLE_GAP_EVT_DISCONNECTED from the host.

Then we re advertize and reconnect in loop.

Only at the first pairing, we have no disconnection:

We are using SDK 15.2.

No issue with Nrf Connect on an Android Smartphone

The BLE_GAP_EVT_DISCONNECTED event has an additional status code. Which one do you get?
