When I read this above and try to understand the problem I have no success. Very rare and confusing information.
We have 3 more or less independent systemes that should be debugged separately:
- drone (flight controller, sensors, ESCs, motors and battery)
- Camera (Gimbal, WiFi hot-spot, camera itself)
- Remote control ST10 (Android, flight mode apps)
Let's start with drone. Red blinking at back light means HW error. In most cases the wiring/connectors to compass and in some cases to GPS module caused problems. Diagnosis: GUI via Serial to USB adapter. You can use YUNA100 or any other.
If there is no connection, check if driver is proper installed. If yes there should be a virtual COM port appear in device manager when you plug in the Serial to USB adapter (no drone connection necessary at this step). GUI should tell what is missing.
If all OK with drone, check binding. ST10 must bind via two separate connections to the other parts of the whole system:
- 5GHz WiFi to camera,
- 2.4GHZ ZigBee (SR24) to drone.
Start with 2.4GHz connection and try if all is working (motors can be started if GPS fix is there, drone can be controlled by sticks).
Mount camera and check if camera offers a WiFi hot-spot with dedicated SSID CGO3_xxxxxx. Check if camera is bound to ST10 and you see the what the camera sees on the screen. If yes, all should be good.
