Removing Wi-Fi from Android Build

Ron Olson

Other Parts Discussed in Thread: AM3517

 

I'd like to remove the remnants of Wi-Fi from our Android build.  Our hardware is similar to the AM3517 EVM, but has no Wi-Fi.  We started with the TI Android 2.3.4 build for the AM3517 EVM, and are now tailoring that build for our board.

I'm looking for this result:

  1. Free the CPU from spending any fruitless time on Wi-Fi.
  2. Minimize size of the build, by excluding unneeded Wi-Fi code.
  3. Remove all evidence of Wi-Fi from the display - such as the signal strength indicator.

I've looked through the porting guide, and although it discusses Wi-Fi, it doesn't directly address configuration of a system without Wi-Fi.

So, I'm looking for suggestions or references to existing info on what I must do to my Kernel and Android builds to remove Wi-Fi.

Thanks,

Ron

    Hi Ron,

    Currently we do not include any drivers or firmware files for AM3517EVM product either in sources or pre-built images.

    From Android Layer, You can disable wifi related services from init.rc and System server from getting started.

    You can remove WIFI settings from Settings Application by editing Settings App Code.

    Signal strength indicator appears only when wifi is connected.

    Regards,

    Arun
