The firmware prints 'SPAXEL READY <MAC>' a few seconds after the flash reset,
once the UART driver has initialised. Previously the browser sent the JSON
payload immediately when the port opened — the bytes arrived while the device
was still booting and were lost, causing a 15 s timeout.
New flow:
1. Open port (with retries for USB re-enumeration)
2. Read serial stream waiting for 'SPAXEL READY' line (up to 30 s)
3. Only then send the JSON provisioning payload
4. Wait for firmware's {"ok":true} acknowledgment (up to 10 s)
The MAC extracted from 'SPAXEL READY <MAC>' is used as a fallback in case
the firmware's JSON response is parsed before the mac field is available.
