combined SPI and WIFI code on nodemcu blocking SPI
#1


Hello,I have built a wifi network which worked fine. then i added SPI commands to transfer data simultaniosly with wifi. if i use spi.write after conn=s.accept() my SPI sends nothing. If i write spi.write before conn=s.accept() it sends SPI sequence as shown in the photo bellow. Why the Socket commands block SPI commands? 

Thanks.


Code:
from machine import Pin,SPI
from time import sleep
import network
import usocket as socket
spi = machine.SPI(1, baudrate=1000000, polarity=0, phase=0)
ap_if = network.WLAN(network.AP_IF)
ssid = 'Sensor network4'
password = '123456789'
ap_if.active(True)
ap_if.config(essid=ssid, password=password)
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.bind(('',80))
s.listen(5)

while True:
    spi.write(b'1234')
    spi.write(b'1234')
    conn=s.accept()
    request=conn.recv(1024)
    request='<p style="color:red"><u></u></p><h1><u>The temperature is:</u><p></p>'
    request2=str(12.9)
    response='gyhkjgku'
    conn.send('HTTP/1.1 200 OK\n')
    conn.send('Content-type: text/html\n')
    conn.send('Connection: close\n\n')
    conn.sendall(request)
    conn.sendall(request2)
    conn.close()
