@kidswong999 我想知道为什么我提的问题不给我回复呢？是我的提问格式不正确，还是没有描述清楚问题，亦或者是你们没见过这个问题呢？能不能给个回复？https://forum.singtown.com/topic/5842/无线扩展模块无法正常使用进行图像信息传输-报错-13-求助解决办法

请问，在使用WiFi扩展板时运行IDE里面的mjpeg_streamer_ap_2.py，能正常建立WiFi热点，但是电脑或其他移动端无法连接，浏览器也无法登陆8080端口，报错代码为-13，隔一段时间后变为-9，请问这是什么原因？应该如何解决才能实现WiFi模块的正常传输。
运行结果截图如下：

示例代码如下：

import sensor, image, time, network, usocket, sys

SSID ='OPENMV_AP'    # Network SSID
KEY  ='1234567890'    # Network key (must be 10 chars)
HOST = ''           # Use first available interface
PORT = 8080         # Arbitrary non-privileged port

# Reset sensor
sensor.reset()
# Set sensor settings
sensor.set_contrast(1)
sensor.set_brightness(1)
sensor.set_saturation(1)
sensor.set_gainceiling(16)
sensor.set_framesize(sensor.QQVGA)
sensor.set_pixformat(sensor.GRAYSCALE)

# Init wlan module in AP mode.
wlan = network.WINC(mode=network.WINC.MODE_AP)
wlan.start_ap(SSID, key=KEY, security=wlan.WEP, channel=2)

# You can block waiting for client to connect
#print(wlan.wait_for_sta(10000))

def start_streaming(s):
    print ('Waiting for connections..')
    client, addr = s.accept()
    # set client socket timeout to 2s
    client.settimeout(2.0)
    print ('Connected to ' + addr[0] + ':' + str(addr[1]))

    # Read request from client
    data = client.recv(1024)
    # Should parse client request here

    # Send multipart header
    client.send("HTTP/1.1 200 OK\r\n" \
                "Server: OpenMV\r\n" \
                "Content-Type: multipart/x-mixed-replace;boundary=openmv\r\n" \
                "Cache-Control: no-cache\r\n" \
                "Pragma: no-cache\r\n\r\n")

    # FPS clock
    clock = time.clock()

    # Start streaming images
    # NOTE: Disable IDE preview to increase streaming FPS.
    while (True):
        clock.tick() # Track elapsed milliseconds between snapshots().
        frame = sensor.snapshot()
        cframe = frame.compressed(quality=35)
        header = "\r\n--openmv\r\n" \
                 "Content-Type: image/jpeg\r\n"\
                 "Content-Length:"+str(cframe.size())+"\r\n\r\n"
        client.send(header)
        client.send(cframe)
        print(clock.fps())

while (True):
    # Create server socket
    s = usocket.socket(usocket.AF_INET, usocket.SOCK_STREAM)
    try:
        # Bind and listen
        s.bind([HOST, PORT])
        s.listen(5)

        # Set server socket timeout
        # NOTE: Due to a WINC FW bug, the server socket must be closed and reopened if
        # the client disconnects. Use a timeout here to close and re-create the socket.
        s.settimeout(3)
        start_streaming(s)
    except OSError as e:
        s.close()
        print("socket error: ", e)
        #sys.print_exception(e)
