[T-Mobile LG G3] motoridersd:
The only huge annoyance I have with WiFi Tether Router is that it has no way to enable/disable tethering externally. The dev flat out told me he won't add any Tasker integration, so I'm stuck with doing a Tasker kludge to make it work automagically when I get in and out of my car. I'm still looking into getting the stock tether app to work, because it would make my Tasker tasks SO much cleaner and reliable.

Here's what I'm doing now to turn tethering on when the phone connects to my car's bluetooth:

The touch.sh script executes an 'input' command with the X Y coordinates of the Enable/Disable tether button. Secure Settings is used to unlock the phone and turn the screen on, otherwise the input command is not applied in the right place.

I need to add tracking of PIDs to make sure tethering is not already enabled or disabled when trying to enable or disable it.

Here are the Tasker profiles if anyone is interested
