DEVLOG #31

The mmWave2 connection problem is finally understood. It was caused by a reproducible dependency on the WLAN transmit power: at around 19.5 dBm, the ESP kept running and received probe requests, but its test AP could not be found and connections failed.

At 10 dBm, the AP worked immediately, csi-test connected again, and 360/360 pings succeeded without a disconnect. Raising the limit reproduced the issue, confirming the dependency. Both mmWave sensors now work reliably.

The TX1 migration is also complete. I verified the candidate firmware and baseline, created two identical 16 MiB backups.

The new app was written to app1 together with the NVS merge and OTA selection. A complete readback of all 16,777,216 bytes matched the expected flash image exactly.

Next: Boot the candidate under the existing safety gates, check that TX1 comes up properly, and run the full comparison.
