DEVLOG #39

All four receivers finally made it through a full 30-minute CSI run together. RX1, RX3 and RX4 are now on C1, while RX2 stays on C. Each delivered around 17–20 matching frames per second, and 99.61% of the shared measurement windows passed the CSI checks.

The RX1↔RX4 peer firmware and recording workflow are also implemented and tested offline now. The actual radio comparison hasn’t happened yet, so I still don’t know whether those extra links will improve positioning.

One annoying bug kept rejecting good data after a 128→64→128 format change. That’s fixed in the offline analysis, along with separate format rules for TX1 and peer links and a recorder completion check.

I also added RX and radar exports that keep raw data, timing and recording boundaries together. That path works in offline tests; it isn’t a new live hardware result.

Next: check both mmWave sensors individually and then together at known points. The shared CSI run is a milestone, but tracking and full-system acceptance are still open.
