    HI Joseph,

    Thanks for your reply.

    1. WLAN driver/firmware version

    Driver version is M6. I mean we use this URL dirver:

    http://processors.wiki.ti.com/index.php/Android_wireless_build_and_porting_guide

    Firmware version:

    Rev 6.1.0.0.335 and Rev 6.1.0.2.349

    2. Which BT firmware?

    I posted BT firmware here. 

    I tested WL1273 again and found actually this issue is also in WL1273. Should be passive scan on 5G chancel,

    active scan on 5G and passive scan on 2.4G chancel is okay for HFP.

    Hi,

    The driver/firmware you are using is very very old...
    I suggest that you upgrade to the wl12xx NLCP drivers

    Please see the link below for build instructions: http://processors.wiki.ti.com/index.php/WL12xx_NLCP_Build_Instructions
    The latest git version tag is: ol_R5.SP7.01
