This is absolutely ridiculous!
Here's my story:
Inspire 1 with dual controls, operating fine for almost a year. On 8-31-16, I followed the prompts on Upgrade Required.
After upgrading, my Slave Controller no longer functions. It powers up, but no communication to the quadcopter, and no communication to the Samsung Galaxy Tab SM-T700, Android 5.0.2. This tablet had been working fine for almost a year until the current upgrade.
For reference, on the Master Controller, things appear to be working fine. The upgrade to DJI Go app 2.8.4 was successful, and it comes up fine on my Samsung S6 SM-G920A (phone). The upgrade on the MC to 1.7.40 was successful. The upgrade to the quadcopter went through, Version 1.9.1.30, which shows up in About. The MC is properly starting the motors, speeding up, and tilting the camera gimbal. I have not launched it, due to the inconsistency with the Slave.
Back to the Slave Controller- no link to either the quadcopter or signal through the USB to the tablet. I swapped USB cables with the known working cable on the Master Side, and even tried it with the Samsung phone. I had successfully downloaded the upgrade to 1.7.40 on the Tablet, but when it went to perform the upgrade, it aborted (since it could not talk to the unit).
I tried the Calibrate Gimbal routine on the Slave and no connection.
Note: the indication at the top of the DJI Go app is the red No Signal box (not the gold Disconnected box)
I tried the nose button / C1 C2 Record or Photo button routine- no effect.
The Slave unit appears to be non-functional. It powers up fine, but no connections.
Again, I’ve been using this exact configuration of phone / tablet / remotes for quite a while, and no problem until the current upgrade attempts.
I had a client demo planned for this weekend, but it looks like I’ll have egg on my face, unless someone knows of a solution! Much appreciated!
thanks
