[PATCH 12/14] rtlwifi: btcoex: 21a 1ant: monitor bt profiling when scan

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Yan-Hsuan Chuang <yhchuang@xxxxxxxxxxx>

When wifi is scanning and not connected, set the tdma and coex table
properly to control the priority of the packets to make the wifi bt
coexistence operate smoothly
