[Nexus 4 Accessories] delrazor:
So I gave up on having NFC tags work with this. They just seem to misfire a lot when docking, either tagging twice or not at all.

I did however come up with a nice scheme for Tasked which turns on Bluetooth and sets some variables along with a bunch of other stuff.

Basically, Carpad>all of my stuff on. If wireless charging stops but I'm still connected to Bluetooth, it won't exit the task. If Bluetooth stops, it'll exit the task.

Its also conditional. If Bluetooth starts and doesn't sense that it has connected to anything within 20 seconds, it won't start all my actions, and instead sets up my routine for using my desktop charger and tells me "goodnight".

Here's my data backup from the Tasker beta which includes a state for wireless charging if anyone is interested.
