Hello, I have several XIAO Esp32-s3 and most of them cannot connect to any Wifi network or open AP for WifiManager... I've already tried some solutions, but without success. Update Arduino board and IDE package -Board and IDE package downgrade ...
WIFI_EVENT_STA_CONNECTED:esp32 成功连上 Wifi 后发生; WIFI_EVENT_STA_DISCONNECTED:掉线后发生,此时可以重新连接。 …… C、调用 esp_netif_set_hostname 函数为 esp32 板子设置主机名。这一步是可选的,如果不设置,默认是“espressif”; D、调用 esp_wifi_init 函数初始化 Wifi; ...
