OK. I got the camera bolted onto the Proaction after I had to order a new Proaction battery.... With the camera powered up I can see two WIFI networks from the camera/gimbal. One is the aformentioned C100E3, which shows up as YUNEEC-C100E3. I noted the Proaction manual says to connect to the YUNXXXX WIFI. I can successfully connect to that WIFI and control the camera. There is also a CGO4-92CA80. I type in the password (1234567890) and try to connect and I get a message from the phone WIFI app "CGO4 Couldn't Authenticate Connection". I Googled the issue and tried numerous options to no avail.
With the Proaction and CGO4 app connected I can control the camera, and can control TILT, but NOT PAN. Pan should work in "G" mode for Global with the tilt/pan joystick on the right side of the Proaction.
