# ESP32 Hacking Roadmap
|
|
|
|
## v0.1 - Documentation & Setup [DONE]
|
|
- [x] Copy firmware sources from esp-csi
|
|
- [x] Document current firmware behavior
|
|
- [x] Document CSI data format
|
|
- [x] Document build & flash process
|
|
- [x] List firmware modification ideas with priorities
|
|
- [x] Verify build from repo (ESP-IDF v5.5.2, aarch64)
|
|
|
|
## v0.2 - Remote Management [DONE]
|
|
- [x] Add UDP command listener on ESP32 (port 5501)
|
|
- [x] Implement REBOOT command
|
|
- [x] Implement IDENTIFY command (LED solid 5s)
|
|
- [x] Implement STATUS command (uptime, heap, RSSI, tx_power, rate, version)
|
|
- [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
|
|
- [ ] On-device wander calculation (simplified)
|
|
- [ ] Reduce to 10 pkt/s when idle
|
|
- [ ] Increase to 100 pkt/s on motion detection
|
|
- [ ] Rate change notification to Pi
|
|
|
|
## v0.5 - BLE Scanning
|
|
- [ ] Enable Bluetooth alongside WiFi
|
|
- [ ] Periodic BLE advertisement scanning
|
|
- [ ] Report device MAC, RSSI, name via UDP
|
|
- [ ] Pi-side BLE device tracking
|
|
|
|
## 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)
|
|
- [ ] Configuration via UDP (WiFi SSID, target IP)
|
|
- [ ] Comprehensive error handling
|
|
|
|
## Future
|
|
- ESP-NOW mesh (ESP32-to-ESP32 CSI)
|
|
- Multi-channel scanning
|
|
- External sensor support (PIR, temp/humidity via GPIO)
|
|
- Power management for battery operation
