Bring an ESP32 sensing node online.

1. Pick a firmware variant

• s3-8mb (display build) — ESP32-S3 N16R8 / 16MB; AMOLED optional. The display-detect fix (#1000) means a bare board still captures CSI (MGMT+DATA).
• s3-4mb (no-display) — ESP32-S3 4MB; dual-OTA, display disabled.
• c6 — ESP32-C6 + Seeed MR60BHA2 (60 GHz mmWave + WiFi CSI). The mmwave probe requires a validated MR60 header (#1107) so an empty UART never false-detects.

Prebuilt binaries: GitHub release v0.8.1-esp32 (hardware-validated on S3 QFN56 rev v0.2).

2. Flash

ESP-IDF v5.4 on Windows is subprocess-only (Git Bash/MSYS is unsupported — strip MSYSTEM* env vars). Offsets for the S3 image:

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

(ruview_node_flash returns the exact pinned command rather than running an unattended flash.)

3. Provision

python firmware/esp32-csi-node/provision.py --port <PORT> \
  --ssid "<SSID>" --password "<secret>" --target-ip <server-ip> --target-port 5005
# optional ADR-060 overrides:
python firmware/esp32-csi-node/provision.py --port <PORT> --channel 6 --filter-mac AA:BB:CC:DD:EE:FF

Never echo or commit the WiFi password.

4. Confirm CSI is flowing

ruview_node_monitor {port} — PASS criteria: serial shows CSI cb #... callbacks and (on a bare board) CSI filter upgraded to MGMT+DATA. No callbacks → the node isn't capturing; do not proceed to calibration.
