- Add device_name module: NVS-persisted custom name with MAC-suffix
fallback (Velxio-XXXX) so every device is uniquely identifiable
out-of-the-box in BLE pairing dialog
- Add wifi_ap module: first-boot SoftAP (Velxio-Setup-XXXX / velxio123)
with embedded HTTP config portal at 192.168.4.1 for renaming
- main.c: enter AP setup mode when no custom name is set
- ble_service.c: use dynamic device name from device_name_get(),
with adv-packet length guard
- led_button.c: BOOT button long-press (5s) factory reset (erase NVS)
- sdkconfig.defaults: enable WiFi stack + set NimBLE default name
Frontend deviceName display already committed in 01f68d3.
v3.1 enhancements (4 Jul 2026):
- Baud dropdown (9600/19200/38400) + CMD_SET_BAUD
- LED blink patterns per-state (IDLE/RECEIVING/FLASHING/SERIAL_BRIDGE)
- Arduino event-based connect/disconnect (CherryUSB)
- Serial terminal always visible saat paired
- Re-deploy fix: serial_bridge_stop before parser
- Dual baud: 115200 STK500 + 9600 serial bridge
- Footer v15, SW cache v14
This is a checkpoint commit. Next cycle: port Deploy from
SvelteKit (DeployTab.svelte) to Velxio React app (native integration).
DeployTab.svelte will be deprecated after port complete.
serial_bridge.c + .h:
- Implement 20pkt/s throttle with 240-byte buffer
- serial_bridge_on_usb_data() for buffering USB serial data
- Flush every 50ms or 500ms stale timeout
led_button.c + .h:
- Per-color LED blink toggle in led_button_tick()
- BLUE_BLINK 200ms, RED_BLINK 100ms, GREEN_BLINK 200ms
- Fix: was set_led(true,true,true) for all blink patterns
main.c:
- Route USB serial data through serial_bridge_on_usb_data
- Add led_button_tick() call in main loop
state_machine.c:
- Add binary_parser_reset() on SERIAL_BRIDGE re-deploy
