[Nexus 4 Q&A, Help & Troubleshooting] unknownprotocols:
Okay, I have Tasker, and my hope is to make my Nexus 4 autoconnect to my ptv3000 miracast adapter. I can manually connect just fine, but I want to find a command that will make the Nexus connect to the miracast automatically instead of having to navigate to display, wireless display, and then click on the adapter name... Quite tedious everytime I start my car... Even a shortcut directly to the wireless display section in settings is a start. I ran logcat recording while I manually connected, but I didn't see what I was hoping to.
