Bluefruit52Lib Library : BLE GamePad or Keyboard connexion bug

[EtienneGameSeed]

Operating System

Windows 10

IDE version

1.8.19

Board

Feather NRF52840 express

BSP version

0.21.0

Sketch

What happened ?

The first time the peripheral is paired, it works. But when I power on/off the Feather NRF52840 again, it fails to keep connected.
It cycles between connected/disconnected (paired).
The Disconnect Reason is "CONN_TERMINATED_DUE_TO_MIC_FAILURE ", but I couldn't figure out what is happening.
You need to suppress the peripheral in windows and pair it again to make it connect permanently again.
Same result with BLE Keyboard or Mouse example. Tested on Windows 8.1 with 3 different BT Dongles (>5.0) and on 2 Windows 10 PCs with integrated Bluetooth.

How to reproduce ?

1. Upload the blehid_gamepad or ble_keyboard or ble_mouse example on a Feather NRF52840 Express
2. Pair the device on the PC
3. Power Off/On or reset the Feather
4. The device will connect/disconnect forever
