No Signal problem

[olefolks]

I am having some problems that I don't how to deal with.
1. When everything is connected, Go 4 shows no signal,
2. There is no satellite connection.
3. There is no battery connection nor battery information.
4. The Gimbal is not connected.

The firmware for the AC and the RC are up to date. I have flown the P4 after the firmware update
a number of times with no problems. Today, all of a sudden the above things have occurred.
Also, I can start the AC engines thru the RC with no problem and then fly the AC I am sure.

Anyone have any ideas?? Sure need some help!!

I had this problem some time ago, I uninstalled go4 and reinstalled that sorted it.

Thanks UK, I have already done that and it was of no help!

Found the problem. App showed "No SD card" when there was one in the slot. I took it out and reinstalled it and everything is fine now. Strange how something like a SD card could affect the P4, app, etc.
