ESP32-S3 CSI node firmware — two field-reported sensing bugs fixed and validated on real hardware (ESP32-S3 QFN56 rev v0.2, 8MB flash / 2MB PSRAM).

Fixes

  • #1000 — no CSI on a bare/display-less DevKit. The SH8601 QSPI AMOLED is write-only, so panel init "succeeds" even with no panel attached; that false-positive left display_is_active() true and starved CSI at MGMT-only frames. Now the readable FT3168 touch controller gates it: no touch readback → run headless → CSI upgrades to MGMT+DATA. (PR #1121)
  • #1107 — false MR60BHA2 detection → ENOMEM. UART probe now requires a validated MR60 header (8-byte SOF + checksum + type 0x0A__/0x0F09) instead of counting bare 0x01 bytes, so an empty UART no longer false-detects a sensor. (PR #1119)

Hardware validation (boot log, rev v0.2 silicon)

disp_hal: SH8601 panel init OK (368x448)            # write-only panel "succeeds" on bare board
disp_hal: FT3168 not found (ret=ESP_FAIL)           # touch readback fails — no real panel
disp_task: ... running headless so CSI captures (#1000)
csi_collector: CSI filter upgraded to MGMT+DATA (no display, RuView#893)
mmwave: No mmWave sensor detected (CSI-only mode)   # no false detect on empty UART

CSI streamed cleanly (frames len 128→384/256), 600 callbacks / 22s, zero crash or watchdog.

Flashing

ESP32-S3, esptool offsets:

esptool --chip esp32s3 -p <PORT> -b 460800 write_flash \
  0x0 bootloader.bin  0x8000 partition-table.bin \
  0xf000 ota_data_initial.bin  0x20000 esp32-csi-node-s3-8mb.bin

4MB (no-display) boards: use esp32-csi-node-s3-4mb.bin @ 0x20000 and partition-table-4mb.bin @ 0x8000.
