Connect Example

This example shows how to connect your OpenMV Cam with a WiFi shield to the net.

import network

SSID='' # Network SSID
KEY='' # Network key

Init wlan module and connect to network

print("Trying to connect... (may take a while)...")

wlan = network.WINC()
wlan.connect(SSID, key=KEY, security=wlan.WPA_PSK)

We should have a valid IP now via DHCP

print(wlan.ifconfig())

提示的很明显了，SSID不能是空。

SSID应该是你的路由器的Wi-Fi名称，KEY应该是你的路由器的Wi-Fi密码。
