|
|
- [x] Implement REBOOT command
|
|

|
|
- [x] Implement RATE command (change ping Hz, NVS persist)
|
|
- [x] Implement POWER command (TX power dBm, NVS persist)
|
|
- [x] Add LED status indicator (off/slow blink/fast blink/solid)
|
|
- [x] NVS persistence for rate and tx_power settings
|
|
- [x] Pi-side `esp-cmd` and `esp-fleet` CLI tools
|
|
- [x] mDNS hostname, watchdog, human-readable uptime
|
|
- [x] Build and flash to device
|
|
- [x] Update CHEATSHEET.md with new commands
|
|
|
|
## v0.3 - OTA Updates [DONE]
|
|
- [x] Dual OTA partition table (ota_0 + ota_1, 1920 KB each)
|
|
- [x] 4MB flash config, custom partitions in sdkconfig.defaults
|
|
- [x] OTA command handler + ota_task in firmware
|
|
- [x] LED_OTA double-blink pattern during download
|
|
- [x] Bootloader rollback on failed update (30s watchdog)
|
|
- [x] Version field in STATUS reply
|
|
- [x] Pi-side `esp-ota` tool (HTTP server + OTA orchestration)
|
|
- [x] `esp-fleet ota` subcommand (sequential fleet update)
|
|
- [x] USB-flash first device (partition table change)
|
|
- [x] End-to-end OTA test
|
|
|
|
## v0.4 - Adaptive Sampling [DONE]
|
|
- [x] On-device CSI wander calculation (coefficient of variation)
|
|
- [x] Reduce to 10 pkt/s when idle (3s holdoff)
|
|
- [x] Increase to 100 pkt/s on motion detection
|
|
- [x] Rate change EVENT notification to Pi via UDP
|
|
- [x] ADAPTIVE ON/OFF command (NVS persisted)
|
|
- [x] THRESHOLD command for tuning sensitivity (NVS persisted)
|
|
- [x] RATE command disables adaptive mode
|
|
- [x] adaptive/motion fields in STATUS reply
|
|
|
|
## v0.5 - BLE Scanning [DONE]
|
|
- [x] Enable Bluetooth alongside WiFi (NimBLE, BLE ON/OFF command)
|
|
- [x] Periodic BLE advertisement scanning
|
|
- [x] Report device MAC, RSSI, name via UDP (`BLE_DATA,<mac>,<rssi>,<type>,<name>`)
|
|
- [x] Pi-side BLE device tracking (`esp-ctl ble --track`, dedup, summary table)
|
|
|
|
## v1.0 - Production Firmware
|
|
- [x] mDNS auto-discovery (done in v0.2)
|
|
- [x] Watchdog + auto-recovery (done in v0.2)
|
|
- [ ] On-device CSI processing (send metrics, not raw)
|
|
- [x] Configuration via UDP (`TARGET <ip> [port]`, NVS persisted)
|
|
- [x] Comprehensive error handling (watchdog, WiFi reconnect via example_connect)
|
|
- [x] `esp-ctl` unified CLI tool (cmd, status, listen, serial, ble, target, profile)
|
|
|
|
## v1.1 - Passive Sensing & Multi-Sensor
|
|
- [x] Sensor ID in data packets (hostname prefix on CSI_DATA, BLE_DATA, EVENT)
|
|
- [ ] WiFi probe request capture (`PROBE_DATA,<sensor>,<mac>,<rssi>,<ssid>`)
|
|
- [x] Deauth/disassoc frame detection (`ALERT_DATA,<sensor>,<type>,<sender>,<target>,<rssi>`)

|
|
- Multi-channel scanning (hop across WiFi channels)
|
|
- RSSI triangulation with 3 sensors (approximate device location)
|
|
- BLE device fingerprinting (identify phone models by advertisement patterns)

|
- Historical presence logging (who was here, when, how long)
|
|
- External sensor support (PIR, temp/humidity via GPIO)
|
|
- On-device CSI processing (send metrics, not raw)
