hci interface stopped working after few hours #ble #hci #nrf52480 #uart

Hi All,

I'm facing issues regarding ble's hci interface.
I'm having nrf52840 module on which i run zephyr's hci_uart app for beacon scanning.
I have Bluez 5.50 installed on my custom board (imx6ull).

hci0 interface on my device is "UP RUNNING". So, i'm able to scan the beacons. (My application scans beacons after every 10 seconds).

Now, When i have put my device for over night testing, then i have observed that after few hoursĀ beacon scanning was stopped.
And i'm getting "Bluetooth: hci0 command 0x200b tx timeout" prints after every 5-10 seconds on the console, still the hci0 interface status is "UP RUNNING", but not able to scan the beacons.

Sometimes also getting the prints like "Bluetooth: hci0: Frame reassembly failed (-84)".

What could be the reason behind this ?
