/*
|
|
* debug_log.c - WiFi 调试日志输出实现
|
|
*
|
|
* 通过 UDP socket 将调试日志发送到上位机
|
|
* 上位机需监听 <DEBUG_LOG_IP>:<DEBUG_LOG_PORT>
|
|
*
|
|
* 支持双通道输出：UDP + UART0 串口
|
|
* UART0: TX=GPIO21, RX=GPIO20, 115200 波特率
|
|
*
|
|
* 时序说明：
|
|
* esp_netif_init() 创建 tcpip 线程后才可安全使用 socket
|
|
* 本模块在首次 debug_log_send() 时才创建 socket（延迟创建）
|
|
* WiFi 连接前 sendto() 会失败（无路由），日志仅走 UART
|
|
* WiFi 连接后 UDP 立即生效，无需额外操作
