# ESP32 Hacking Tasks

**Last Updated:** 2026-02-04

## Current Sprint: v0.2 - Remote Management

### P0 - Critical
- [x] Firmware: UDP command listener (port 5501)
- [x] Firmware: LED status indicator (GPIO2)
- [x] Firmware: NVS config persistence (rate, tx_power)
- [~] Build and flash firmware to device

### P1 - Important
- [x] Firmware: REBOOT, IDENTIFY, STATUS commands
- [x] Firmware: RATE command (10-100 Hz, restarts ping)
- [x] Firmware: POWER command (2-20 dBm)
- [x] Firmware: Refactor ping to support restart
- [x] Pi-side: `esp-cmd` CLI tool
- [ ] Update CHEATSHEET.md with esp-cmd usage

### P2 - Normal
- [ ] Document esp-cmd in USAGE.md
- [ ] Add Kconfig CSI_CMD_PORT option

### P3 - Low
- [ ] Document esp-crab dual-antenna capabilities
- [ ] Document esp-radar console features

## Completed: v0.1 - Documentation

- [x] Copy firmware sources to project
- [x] Document current firmware and settings
- [x] Document build & flash workflow
- [x] Create .gitignore for build artifacts
- [x] Test building firmware from this repo
- [x] Document CSI config options
- [x] Compare csi_recv vs csi_recv_router differences

## Notes

- Build confirmed working on ESP-IDF v5.5.2 (aarch64/Pi 5)
- v0.2 firmware adds ~1.5 KB heap + 6 KB stack usage
- NVS namespace: `csi_config` (keys: `send_rate`, `tx_power`)
- LED uses GPIO2 (built-in on most ESP32 dev boards)
- Command port default: 5501 (configurable via menuconfig)
