Help! My Inspire works great! but I wanted to add a 2nd controller. 1 The 1st controller works great ,running a Nexus 7 tablet. 2 The 2nd controller works as "slave" preforms all camera functions......just no video,says "disconnected" using a Samsung tab 4 3 when I switch the Nexus 7 to the 2nd controller I have video! When the Samsung tab 4 is on the 1st controller it has full function but no video. 4 I have tried a Asus running android 4.4.2...... still no 2nd screen. 5 I tried to switch the controllers from "master" to "slave" and reverse them but only one will switch? The other wont to to" master" I have tried for about 3 hrs total ( several different times) I am sick of buying new tablets to try. This is driving me crazy! I have tried so many different ideas and ways to get past this.....I need more help. Thank You for your time!
