Hi All,

   We have SDIO Interface supported wifi card, Can we use that module for android driver porting ?

   We tried but wifi card is not detecting in Android Kernel.

   Please help me to use SDIO Interface based Wi-Fi Card.

Regards,

Thanaraj.

Hi Thanaraj

yes it can be used, please refer to attached Linux Manual

Chapter 46 Wi-Fi BCM4339 Driver, the same is for Android as

described in Release Notes Table 2. Features. Usually porting

guidelines are provided by chip vendor.

Best regards
igor

Hi igor,

   We are not using BCM Driver. But Generally if we insert the SDIO Card it should get detected by kernel. But here SDIO Card is detected and immediately card removed.
