WILINK8-WIFI-NLCP: Wilink8 : BLE : HCI TX timeout intermittently

Adam Ruehl

Hi,

While connected to 2 BLE devices and transmitting (AM335x Host + Wilink8 as the Central), I see the following log on the AM335x console:

[31383.183818] Bluetooth: hci0 command 0x0401 tx timeout [31430.053810] Bluetooth: hci0 command 0x200c tx timeout

This appears to be cleared up be reseting the BT side and re-attaching to the hci device. This happens after anwhere from 9 hours of operation up to 12 days sometimes. Both WiFi and BT are active simultaneously and WiFi continues operating normally.

Are there any known issues with long duration use of the Wilink8?

Regards,

Adam

Hello Adam,

There is a known issue of Voice channel quality after about 20 hours.
however the timeout can be caused by many different parameters.
Can you please share a fw logger output and a sniffer log so we can investigate this issue.
