I reached out to the PicoScenes developers and was able to get a donated PicoScenes license (which avoids us having to deal with the issues of the ESP32). The high-precision clock sampling seems to work and I’m able to read the relevant packet metadata from Python; however it is limited to 40mhz clock speed (because we are on 2.4ghz which has limited width bands). It also does not detect our ping packets for some reason (possibly due to them being malformed packets).
Next week I’ll be working on figuring out how to work around these two issues (the packet issue would likely be by formatting the packets to have additional fields so PicoScenes parses them correctly, but I’m still unsure how to deal with the 40mhz limitation); that should bring us to a point where we can collect data to test our algorithms against.
