feat: firmware update via Web UI (OTA upload, URL download, UF2, rollback)#3
Conversation
…rollback, UF2 Implements 6 HTTP handlers in api_firmware.c: - GET /api/firmware/status: version, partition, OTA state, progress - POST /api/firmware/upload: chunked binary OTA via httpd_req_recv - POST /api/firmware/url: async OTA download via esp_http_client task - POST /api/firmware/rollback: mark app invalid and reboot - POST /api/firmware/uf2: enter USB UF2 bootloader mode - POST /api/firmware/confirm: mark running app as valid
After WiFi and VPN initialization, check if the running firmware is pending OTA verification. If so, poll for network connectivity (STA connected or AP mode) up to a configurable timeout. On success, mark the firmware valid; on timeout, reboot to trigger automatic rollback to the previous firmware.
- Remove racy ota_init_once(); add api_firmware_init() called from webui_init() - Add Content-Length check at start of upload handler - Add URL length and scheme validation in URL download handler - Add 10s stall protection in download task (zero_count > 100) - Move OTA rollback check after webui_start() for web-based confirmation - Bump max_uri_handlers from 32 to 40 - Disable upload/download buttons in frontend when OTA is busy
