Soft Access Point & Socket Data Streaming - groger57 - Jul-31-2019
Hello:
I am new to this forum. I am having an issue trying to figure out how to do something seemingly simple, but spinning the wheels. I have searched as many resources as I can, but do not seem to able to find an example. Even books I have bought do not cover how to do this, they're really focused on running the device in 'station mode'.
The device I am using is the ESP32, which I want to act as a soft access data "server". Here's the objective:
-boot the ESP32 in WAP (soft access) mode
-controller begin processing data from the ADC
-wait for connection
-when connection is initiated, begin streaming data at rate 'x". For this I will use a controlled loop or a thread.
-the data will be integers in the range of int16's
At the other side (client) the laptop (for now) will launch a console application to connect to the soft point and receive data and display it in the console.
That's it! My weakness is with using sockets...what I have so far is below. Seems it should be something that is common application, but after many searches I cannot find a basic example.
Can someone provide the missing pieces, or let me know of a resource that I could read to understand how to do this?
Thanks!
Gary
import socket
import network
ap = network.WLAN(network.AP_IF)
ap.active(True)
ap.config(essid='CPTS-A3D', authmode=network.AUTH_WPA_WPA2_PSK, password='password')
ap.ifconfig(('192.168.4.1', '255.255.255.0', '192.168.4.1', '192.168.4.1'))
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
#pick a port...should this call be: s.bind(('0,0,0,0', 10000)) ??
s.bind(('', 10000))
s.listen(5)
while True:
conn, addr = s.accept()
#display activity
print('Got a connection from %s' % str(addr))
#should this be less bytes for what I need to do?
request = conn.recv(1024)
# THIS IS WHERE I AM TRYING TO FIGURE OUT
#HOW TO SEND DATA
#the next line is part of the 'web server/html' code I found
#not sure if it will be part of the solution
conn.sendall(response)
conn.close()

I set it solved because I recognize now I posted a primitive question for everyone here. Sorry to bother you all.
