All you need to do is make sure the base stations are using correct channels.
Just turn on the base stations while your Pimax is up and running, then:
- Grab a needle or something sharp
- Push once with the needle inside the small hole at the back of your base station (see image below).
- Now wait a few seconds
- If channel is correct, your base station icon in PiTool will blink and then become blue (active) in PiTool.
- If channel is not correct, the base station will stay grey in Pitool. Then try pushing one more time with the needle, and repeat step 2 to 5 until both your base stations are detected in PiTool.
This is only required to be made once, and the channels will be saved for all later use.
