BT keeps on asking me if I want to allow car to do stuff

We can remember it as a non persist global value when user click no.
This value won't be saved when power down.
We will restore the permission choice
when we are disconnected with the remote device.
So the "no" choice selected by user will only take effect
until we are disconnected with the remote device.
