The project was designed around a 10.60.1.0/24 travel-router network,
but the actual RemoteRig router uses 192.168.8.0/24 (the C6 associates
and gets 192.168.8.x; hub confirmed at 192.168.8.56). Replace the
network prefix everywhere (last octet preserved; GoPro 10.5.5.1 left
alone).
- scripts/setup-pi.sh: static IP 192.168.8.56/24, gateway 192.168.8.1,
deploy/health command examples updated
- esp32-mqtt-bridge.cpp: default mqtt_broker -> 192.168.8.56
- firmware/data/config.json: broker -> 192.168.8.56 (wifi_password kept
blank in git; real value flashed to the device only)
- docs (CONTEXT, MQTT_CONTRACT, READMEs, wireframes): gateway/hub/DHCP
and example IPs re-addressed for consistency

Updating the buried ESP-01S currently means a USB-UART adapter and a
GPIO0 jumper. Add a path to change its settings without reflashing, and
lay the groundwork for full firmware updates over the existing UART.
set_config (no reflash for settings):
- ESP-01S: add saveConfig() + a set_config command — updates GoPro
SSID/password/IP and poll interval, persists to LittleFS, acks, and
re-associates Wi-Fi if creds changed
- XIAO: forward an MQTT set_camera_config down to the ESP-01S over UART
(hub -> MQTT -> XIAO -> UART -> ESP-01S/LittleFS)
UART-OTA groundwork ("XIAO as flasher"):
- reserve XIAO GPIOs ESP01_RST_PIN=D8, ESP01_PGM_PIN=D10 for driving the
ESP-01S serial bootloader (not driven yet)
- docs/design/esp01s-uart-ota.md: full design (why Wi-Fi OTA doesn't fit
the 1MB ESP-01S on the GoPro AP, bootloader entry, ROM flash protocol,
HTTP-pull delivery, scope)
- hardware/README.md: fix stale ESP32-C3 -> XIAO ESP32-C6 wiring, add the
two control lines (Notion wiring diagram updated to match)
Both firmwares build clean and are flashed; set_config round-trip needs
the broker to exercise end-to-end.

- Add dedup check in handleStatus using (camera_id, recorded_at) uniqueness
- Skip insert if duplicate detected - logs replayed entries
- Go mod: updated version to 1.19
Rotatable 3D render of the tripod-mounted dual-ESP case:
- Case body with rounded corners and lid
- Stacked ESP32 + ESP8266 boards inside
- LED indicator, USB port, ventilation slots
- Tripod pole with C-clamp mount
- USB cables, screws, chip details
- Drag to rotate, scroll to zoom
- Open in any browser
Replaced GoPro-sleeve case design with simpler stand-mounted box:
- Case clips to tripod leg/stand pole (20-35mm diameter)
- No camera sleeve needed — case sits on the stand
- Powered by standard USB power bank (off-the-shelf)
- Holds ESP8266 + ESP32 stacked with UART wiring
- Cable ports for USB in/out, LED window, ventilation
Simplified BOM: ~1/node (down from 4), no buck converters needed
Complete rewrite of firmware into two dedicated boards per camera node:
ESP8266 (Camera Bridge):
- Connects ONLY to GoPro AP — polls status, sends over UART
- Zero network switching, zero MQTT
- HTTP GET /bacpac/SH for status, start/stop
- JSON-per-line UART protocol to ESP32
ESP32 (MQTT Bridge):
- Connects ONLY to travel router — MQTT to Pi hub
- Reads status from ESP8266 over UART2 (RX16/TX17)
- Auto-registration, heartbeat, command forwarding
- Zero camera communication
UART Protocol: JSON-per-line at 115200 8N1
ESP8266→ESP32: status/ack/pong/error
ESP32→ESP8266: cmd (start_recording/stop_recording/ping)
Hardware updates:
- BOM now includes both boards (~4/node)
- 3D case has stacked dual-board compartment
- UART wire channel between board recesses
- Shared 3.3V power rail for both boards
- GoPro Hero 3 sleeve with lens/screen/USB cutouts
- ESP32 D1 Mini electronics compartment (vented)
- LiPo battery compartment with velcro strap slots
- Bill of materials (~0 per camera node)
- Wiring diagram (LiPo → dual buck converters → ESP32 + GoPro)
- Field deployment workflow
