DEVLOG #30

The replacement ESP for mmWave2 is now soldered and mounted on the previously working breadboard setup. The connection problem has not disappeared, however WiFi still fails, so I uploaded a minimal WiFi test script to isolate the radio and network path before testing the radar or UDP transport.

The mmWave firmware now distinguishes MMWAVE1 and MMWAVE2 with separate build and upload paths, uses 55010 as the default UDP port, and logs the WiFi disconnect reason. These changes are prepared locally; the test image is not yet a confirmed fix, and the complete mmWave2 path is still unvalidated.

In parallel, the TX1 replacement reached a stronger local checkpoint. Reproducible builds from fresh and isolated source copies are byte-identical, and the local test suite passed. The 7A TX1/RX4 baseline still produced no usable measurement data, so the migration remains blocked and 7B is NO-GO.

Next: resolve the WiFi connection on the replacement ESP, verify mmWave2 communication, and continue with two-sensor validation and RX3 calibration.
