Lost packet on RX (Central->Device)

Hi,

When working with Windows 10 laptop BLE we get sometimes a lost packet occurrence from Central (PC) to our BLE device.

We are using a Python Bleak based app on the Windows side. Our device is nRF52840 based.

Attached is a sniffer trace caught in WireShark, using the BLE Sniffer addin. We detected the lost packet using an Index/CRC mechanism in the payload. Device did not receive index 15306, but in the sniffer we can see it line No. 201659, payload begins with 0x34C2 (15306 decimal).

PC laptop model is Dell 7490.
