Using the WiFi connection, we can create a HTTP simple webserver on the module with the socket library.
|
|
|
|
```python
|
|
import usocket
|
|
import _thread
|
|
import time
|
|
from network import WLAN
|
|
import pycom
|
|
|
|
availablecolor = 0x001100
|
|
connectioncolor = 0x110000
|
|
|
|
# Thread for handling a client
|
|
def client_thread(clientsocket,n):
|
|
# Receive maxium of 12 bytes from the client
|
|
r = clientsocket.recv(4096)
|
|
|
|
# If recv() returns with 0 the other end closed the connection
|
|
if len(r) == 0:
|
|
clientsocket.close()
|
|
return
|
|
else:
|
|
# Do something wth the received data...
|
|
print("Received: {}".format(str(r))) #uncomment this line to view the HTTP request
|
|
|
|
http = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\nConnection:close \r\n\r\n" #HTTP response
|
|
|
|
if "GET / " in str(r):
|
|
#this is a get response for the page
|
|
# Sends back some data
|
|
clientsocket.send(http + "<html><body><h1> You are connection "+ str(n) + "</h1><br> Your browser will send multiple requests <br> <a href='/hello'> hello!</a><br><a href='/color'>change led color!</a></body></html>")
|
|
elif "GET /hello "in str(r):
|
|
|
|
clientsocket.send(http + "<html><body><h1> Hello to you too! </h1><br> <a href='/'> go back </a></body></html>")
|
|
elif "GET /color" in str(r):
|
|
pycom.rgbled(0xFFFFFF)
|
|
clientsocket.send(http + "<html><body><h1> You are connection "+ str(n) + "</h1><br> Your browser will send multiple requests <br> <a href='/hello'> hello!</a><br><a href='/color'>change led color!</a></body></html>")
|
|

# Close the socket and terminate the thread

clientsocket.close()

wifi = WLAN()
|

wifi.init(mode=WLAN.AP, ssid="hello", auth=None, channel=1)
|

print("WiFi is up!")
|
|
time.sleep(1)
|
|
pycom.heartbeat(False)
|
|
pycom.rgbled(availablecolor)
|
|
|
|
# Set up server socket
|
|
serversocket = usocket.socket(usocket.AF_INET, usocket.SOCK_STREAM)
|
|
serversocket.setsockopt(usocket.SOL_SOCKET, usocket.SO_REUSEADDR, 1)
|
|
serversocket.bind(("192.168.4.1", 80))
|
|
|
|
# Accept maximum of 5 connections at the same time
|

serversocket.listen(5)

while True:

(clientsocket, address) = serversocket.accept()
|

# Start a new thread to handle the client
|
|
_thread.start_new_thread(client_thread, (clientsocket, c))

|

serversocket.close()
