运行圆形识别代码并同步无心啊传输数据，socket error 返回-13 什么意思，如何解决？

[nxq5]

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

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

green_threshold = ( 0, 80, -70, -10, -0, 30)

Reset sensor

sensor.reset()

Set sensor settings

sensor.set_contrast(3)
sensor.set_brightness(1)
sensor.set_saturation(1)
sensor.set_gainceiling(16)
sensor.set_pixformat(sensor.GRAYSCALE)
sensor.set_framesize(sensor.VGA)

sensor.set_windowing((320, 240))

Init wlan module in AP mode.

wlan = network.WINC(mode=network.WINC.MODE_AP)

Init wlan module in Download mode.

#wlan = network.WINC(mode=network.WINC.MODE_FIRMWARE)

For ATWINC1500-MR210PB only.

#wlan.fw_update("/winc_19_6_1.bin")

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 response(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: application/json\r\n" \
            "Cache-Control: no-cache\r\n" \
            "Pragma: no-cache\r\n\r\n")

# FPS clock

if blobs:
    for b in blobs:
        img.draw_rectangle(b[0:4]) # rect

client.send(json.dumps(blobs))
client.close()

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)
    response(s)
except OSError as e:
    s.close()
    print("socket error: ", e)
