Disable WiFi When Disconnected from Data

[bubba925]

So a lot of vehicles now maintain power to USB after the vehicle is off. I've been dealing with this for some time and resorted to a usb switch that I toggle. I forget to toggle it often enough I've just reverted back to a cable. No options on my truck to disable this "feature" so I'm looking here. Anyone have an idea on if this would be possible through rooting and a firmware update?

Whether Wi-Fi is on, or Bluetooth is on, doesn't matter. What matters is that C2A pings your phone via Bluetooth and that starts the whole process. The phone by itself doesn't ping C2A first.

Maybe (likely) some of original config switches will made it so that it will stop pinging your phone when car connection is not there.
