What WiFi do you want to see? For what?
WiFi connection to your home router is only useful in pad mode for, ehh - I don't know. Update time that's it. ST16 is for surfing or games. I deactivate home WiFi. connection (forget SSID).
For normal drone operation there are two channels:
- 2.4GHz ZigBee connection: This is used to control the drone and the camera movements. Good to fly.
- 5GHz WiFi connection to get video downstream (RTSP protocol) from camera. In this case not the home router is the master but the camera offers a WiFi hot spot with DHCP. You will get your IP address from the camera. If you don't have a camera you don't need it at all because there is no video.
Between drone, gimbal and camera is a serial 2-wire connection (UART). Over this UART some information like FW versions and many other will be send to camera and camera sends it via WiFi to the ST16. That's why you cannot see the SW version when no camera and thus no WiFi network is available.
If you don't have a camera go flying - you don't need the WiFi.
Background:
The subnet that camera offers is 192.168.42.0/24, camera as master has 192.168.42.1. If one connect to the camera, the camera gives him 192.168.42.2, second partner 192.168.42.3 and so on. Camera is not a router, no internet connection possible and this is good so. We control an aircraft and no toy.
