openmv连上刚买的WIFI扩展板,没有报错winc1500无法初始化,但是例程scan跑了没反应。WIFI扩展板不亮灯,也不发热,怎么解决?

socket error: [Errno 22] EINVAL
这个错误是什么情况?
在运行mjpeg_streamer_AP的时候报的错

Traceback (most recent call last):
File "", line 7, in
这个scan例程,教程里面正常是line 11
我这里是line 7出错,有影响吗?Scan Example
This example shows how to scan for networks with the WiFi shield.
import time, network
wlan = network.WINC()
print("\nFirmware version:", wlan.fw_version())while (True):
scan_result = wlan.scan()
for ap in scan_result:
print("Channel:%d RSSI:%d Auth:%d BSSID:%s SSID:%s"%(ap))
print()
time.sleep_ms(1000)

确认OpenMV焊接了插针,WiFi扩展板插对方向。
按照视频步骤操作:
