1. The SDK first calls tkl_wifi_set_work_mode to set the Wi-Fi working mode to station (it will be set to ap mode later)
2. After obtaining the Wi-Fi information, it starts connecting to Wi-Fi. It will print "__wifi_net_conn." The SDK calls tkl_wifi_set_work_mode to set the Wi-Fi working mode to station. It also calls tkl_wifi_ioctl to connect to Wi-Fi. If this interface is not supported, it will call tkl_wifi_station_connect to connect to Wi-Fi
3. tkl_wifi informs the SDK of the Wi-Fi connection status
4. The SDK calls tkl_wifi_station_get_status to get the Wi-Fi status. Only when the callback status is WFE_CONNECTED and the status of tkl_wifi_station_get_status is WSS_GOT_IP, the Wi-Fi connection is considered successful, and it prints: link[2][1] is_up[1] active_link[2][1] status[0]
