如何使用2个AP（wifi 路由器）时dns无法更新目标IP？

问答对人有帮助，内容完整，我也想知道答案 0 我使用 IDF_V4.4.1 我尝试使用 WIFI 发送一些文件我使用 2AP（wifi 路由器）首先我的 esp 已连接 AP（wifi 路由器）-A 并将文件发送到目的地。 1 分钟后，我的 esp 已连接 AP（wifi 路由器）-B 并将文件发送到目标（相同的目标）但目标 ip 没有更新.. 我的 esp 有 172.20.10.2 但目标 ip 有 192.168.1.72（以前的 ip）。如何解决这个问题？？？请帮我代码：全选 I (21753) wifi:AP's beacon interval = 102400 us, DtiM period = 3 I (24253) esp_netif_handlers: sta ip: 192.168.0.5, mask: 255.255.255.0, gw: 192.168.0.1 I (24253) BF_WIFI: got ip:192.168.0.5 I (24253) BF_WIFI: WI-FI connect bit result: 0x1 I (24253) BF_WIFI: connected to ap SSID:RnD_Office password:body_rnd W (24263) APP_MAIN: [BleWifiConnTask]Success to connect WIFI I (24273) APP_MAIN: WIFI_Total_SendJson W (24273) HTTP_CLIENT: max_redirection_count 50 I (24283) APP_MAIN: [WIFI_Total_Http_Send]success to esp_http_client_init W (24283) HTTP_CLIENT: set post file length = 36 W (24293) HTTP_CLIENT: Begin connect to: https://log.bodyfriend.co.kr:443 W (24303) esp-tls: host:log.bodyfriend.co.kr: strlen 20 W (24323) wifi:idx:0 (ifx:0, 58:86:94:9b:16:50), tid:0, ssn:2, winSize:64 W (24333) esp-tls: addrinfo->ai_family == AF_INET W (24333) esp-tls: [sock=-1] Resolved IPv4 address: 192.168.1.72 W (24343) esp-tls: [esp_tcp_connect]fd 54 addrinfo->ai_addrlen 28 W (24343) esp-tls: connecting...
