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.
Akar masalah:
- 4a6ef8c menambah binary_parser_reset() di handler re-deploy SERIAL_BRIDGE
yang menghapus expected_total_crc setelah INIT — menyebabkan CRC mismatch
di END. Source 1d3a489 sudah menghapus reset-nya, tapi device butuh rebuild.
- cad90eb merutekan DATA melalui sendCommand() dengan readPoll state===1
yang selalu true saat DATA — write gagal dilaporkan sukses.
Perbaikan:
1. readPoll pintar untuk DATA: state===1 tidak lagi dianggap sukses.
readPoll hanya fast-fail di state>=5; deadline fallback hanya ok
jika writeValueWithResponse sukses (GATT write response = bukti delivery).
2. INIT_ACK_INDEX=0xFFFE (Fase 3): inisialisasi INIT dengan index unik
menghilangkan tabrakan dengan DATA[0] (index 0). binary_parser.c echo
index recv di ACK INIT. Guard handleFlashingNotification diperluas.
3. pendingAcks.clear() di awal deployHex mencegah poisoning antar deploy.
4. Track firmware inti ke git: binary_parser.c, checksum.c, stk500v1.c,
usb_host.c + headers + CMakeLists + sdkconfig + partitions.
Build: ESP-IDF v6, ESP32-S3, flash via /dev/ttyACM0
