I have the same exact issue and I’ve just received the Base Stations as well. Did some digging into the problem, also with the help of Pimax support, that I must say has been responsive.
Please note that it is NOT the LED of the BS blinking blue, but the PiTool BS Icon. The channel 2 BS is not tracking, no matter what.
It seems that the BASECALIBRATION parameter of the BS is set to 0, 0, 0, 0, 0, 0, 0 and this is the problem… and I couldn’t find a way to set that param.
To check this, you could open up a command prompt and in the PiTool runtime folder execute the command lighthouse_consolle.exe , then type dis …
You should see a line of [0 0 0 0 0 0 0 0 0] or something… this would confirm you’re in my same situation, but at least it’s a common problem that could find a common solution.
Also you could check the file lighthousedb.json in the folder …ProgramData/pimax/runtime/config/lighthouse to see if you find a basecalibration paramater set to a row of 0.
