    I am using the DM3730 SOM Torpedo W/O wifi module. Is there a way to build android without the wifi/bt? The reason I ask is if I don't remove it, the device does not sleep properly and also periodically slow down the system. I can see this in API apps such as rotating cube and such. It would be smooth for about 1 second and then it would slow down before speeding up again.

    OK problem solved.

     

    It is hackish, but it works for what I need to do.

     

    Here is the fix:

    remove btwilink.ko and wl12xx_sdio.ko from system/modules folder in rootfs. This will essentially removes the drivers so it wont be looking for the device when it's on or sleeping. The whole system is a lot smoother and sleep current is down to 1-2mA.

     

    Keep in mind, you might want to remove the wif and bluetooth control in the settings apps to prevent users to accidently turn it on and do something funny to the system
