Led on, off via ap network and python request

 Led on, off via ap network and python request

Can't get micropython to .find '/ ledon' if sent by python on PC, so have changed parameters to Pledon and Pledoff. Works ok but now micropython server code not compatible with browser Chrome. To be fixed. It's that damn '/'. 

Here's the newish micropython code from Thonny:

#Now called WiFiSensor0.py from old WiFiAPLEDS3.py. Going to add internal temperature logging

#Worked ok Tue Aug  6 11:04:01 NZST 2024. Can't get other mode to work  Will play with this one.

import network

import time

import socket

#from machine import Pin

import machine




# led = Pin(25, Pin.OUT)

# led.off()

# led.on()



led = machine.Pin("LED", machine.Pin.OUT)

#led.off()

led.on()

adcpin = 4

sensor = machine.ADC(adcpin)

def ReadTemperature():

  adc_value = sensor.read_u16()

  volt = (3.3/65535) * adc_value

  temperature = 27 - (volt - 0.706)/0.001721

  return round(temperature, 1)

  

  


# def web_page():

#   return html

#todo make this HTML into separate file


# if you do not see the network you may have to power cycle

# unplug your pico w for 10 seconds and plug it in again

def ap_mode(ssid, password):

#todo make led_on report true (not -1), if it sees ' ledon' (Chrome requests) or 'Pledon' (Python requests) OR statement should work.

      led_on = request.find('Pledon')  #Python sends 'Pledon' in request string parameters

      led_off = request.find('Pledoff')

      print( 'led on = ' + str(led_on))

Here's the PC python code:

import requests

foo = ' /ledoff'
response = requests.get('http://192.168.4.1', params={'Pledoff':'bar'})
#response.raise_for_status()
print(response.text)
---------------------------------------------foo and bar don't do anything

Here's associated screen shot:

Reading LittleFS file into buffer for sending

 Reading LittleFS file into buffer for sending to another ESP32 via ESP Now. Created dummy file 1321 bytes long with "sensor" information in the form like this:     uint8_t sensorData1[] = "[ 00 12:05:12:06:01 22 33 44 \n"; Red stuff above is timestamp to later get in real time from DS3231.  Blue stuff is dummy sensor information, two ascii chars representing 00 to 99. Black stuff is just formatting chars and spaces. The following program reads in about 43 lines of sensor information as above and puts it into LittleFS file called sensorReadings.txt. This file then gets cut up into 200 byte chunks (via sendBuf[200] ) and gets sent to dummy sender file called sendNowBuf(). No actual sending takes place, so next sub-project is to send the 200 byte chunks one by one via ESPNow to second ESP32. //41 From Arduino Examples/mnt/c/Users/Dell/Documents/Arduino/Working202411/LITTLEFS_test2/LITTLEFS_test2.ino #include <Arduino.h> #include "FS.h" #include <Li...
