Dual OTA partition table (ota_0/ota_1, 1920 KB each) on 4MB flash. Firmware gains OTA command, LED_OTA double-blink, version in STATUS, and automatic rollback validation. Pi-side esp-ota tool serves firmware via HTTP and orchestrates the update flow. esp-fleet gains ota subcommand.

# ESP32 Hacking Tasks
|
|
|
|
**Last Updated:** 2026-02-04
|
|
|
|
## Current Sprint: v0.3 - OTA Updates
|
|
|
|
### P0 - Critical
|
|
- [x] Create dual OTA partition table (`partitions.csv`)
|
|
- [x] Update `sdkconfig.defaults` (4MB flash, custom partitions, rollback, HTTP OTA)
|
|
- [x] Firmware: OTA command, ota_task, LED_OTA, rollback validation
|
|
- [x] Firmware: Add version to STATUS reply
|
|
- [ ] `idf.py reconfigure` to regenerate sdkconfig
|
|
- [ ] Build and USB-flash first device (partition table change requires USB)
|
|
|
|
### P1 - Important
|
|
- [x] Pi-side `esp-ota` tool (HTTP server + OTA orchestration)
|
|
- [x] `esp-fleet ota` subcommand (sequential fleet OTA)
|
|
- [ ] Test OTA end-to-end: `esp-ota amber-maple.local`
|
|
- [ ] Regenerate `sdkconfig.sample`
|
|
|
|
### P2 - Normal
|
|
- [ ] OTA update remaining fleet (muddy-storm, hollow-acorn) via USB
|
|
- [ ] Test rollback (flash bad firmware, verify auto-revert)
|
|
- [ ] Document esp-ota in USAGE.md
|
|
|
|
### P3 - Low
|
|
- [ ] Document esp-crab dual-antenna capabilities
|
|
- [ ] Document esp-radar console features
|
|
|
|
## Completed: v0.2 - Remote Management
|
|
|
|
- [x] Firmware: UDP command listener (port 5501)
|
|
- [x] Firmware: LED status indicator (GPIO2)
|
|
- [x] Firmware: NVS config persistence (rate, tx_power)
|
|
- [x] Firmware: REBOOT, IDENTIFY, STATUS commands
|
|
- [x] Firmware: RATE command (10-100 Hz, restarts ping)
|
|
- [x] Firmware: POWER command (2-20 dBm)
|
|
- [x] Pi-side: `esp-cmd` CLI tool
|
|
- [x] Pi-side: `esp-fleet` fleet management tool
|
|
- [x] mDNS hostname, watchdog, human-readable uptime
|
|
- [x] Build and flash to device
|
|
- [x] Update CHEATSHEET.md
|
|
|
|
## 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
|
|
|
|
## Notes
|
|
|
|
- NVS offset changes with new partition table — first USB flash resets saved config
|
|
- First device must be USB-flashed to switch partition table, subsequent updates via OTA
|
|
- `esp_https_ota` is built into ESP-IDF core — no extra deps needed
|
|
- OTA download ~790 KB on LAN takes ~3-5s, well under 30s watchdog
|
|
- CSI data keeps flowing during OTA download
