- aes67_syslog: esp_log_set_vprintf hook chained to the UART; formats
into a static buffer under a zero-timeout mutex (drop and count when
busy), strips ANSI codes, parses level/tag, filters by log.level and
queues (48 messages, non-blocking). Low-priority sender task: RFC 5424
(<PRI>1 - HOST APP - - - MSG, no timestamp yet) or RFC 3164
(<PRI>HOST TAG: MSG), PRI = facility*8 + severity; log.host as IP or
resolved name; config applies live. Messages wait in the queue until
the interface has an IP. POST /api/log/test sends an info message
regardless of the level filter.
- Initialised first in app_main so boot messages are captured; the UDP
socket is created only once the interface is up (creating it before
esp_netif_init crashed at boot and the bootloader rolled back).
- Verified with a UDP listener: 5424 and 3164 formats, PRI 134/132,
boot messages delivered after the IP came up, shutdown messages sent
before reboot, level filter, test message, host by DNS name.
