hci_num_completed_packets - packet count mismatch

[Austin Hellenbrand]

Hello,

OS: nRF Connect SDK v2.3.0
HW: nRF5340 running on a custom board

SW: Custom BLE Peripheral based off of the BLE Throughput sample

I'm running into an issue where I see an error message stating "packets count mismatch" in hci_num_completed_packets in hci_core.c. I was hoping someone could shed some light on why this might be happening. The app sends notifications (approx. 240 bytes) to a connected central device every 15 ms. The issue usually occurs about an hour after the notifications start. Once I see the error message the central device stops seeing notifications. 

I know this isn't a lot to go on but I'm just looking for some sort of guidance. 

Thanks,

Austin
