#The Code
#The email function is driven by the umail module. This has been published on GitHub by shawwwn. 
#To make use of the module we will need to download it from GitHub and then copy it over to our Pico. 
#I found this most easily accomplished by first downloading the file to the main computer and then 
#going File >> Open on Thonny and selecting the appropriate file. From there go File >> Save as… 
#and select the Pico as the location to save the file (making sure to save it with the appropriate 
#name (umail.py)).
#
#Our code is fairly straight forward in that it imports the appropriate modules, creates the WiFi 
#connection and then sends the email (not forgetting the secrets file) and looks like the following;

import network
import time
import umail
from secrets import secrets

# Set up Wifi
ssid = secrets['ssid']
password = secrets['pw']
rp2.country('NZ') # change to your country code

wlan = network.WLAN(network.STA_IF)

ip = secrets['ip']
netmask = secrets['netmask']
gateway = secrets['gateway']
dns = secrets['dns']

wlan.active(True) # activate the interface
if not wlan.isconnected(): # check if connected to an AP
    print('Connecting to network...')
    wlan.connect(ssid, password) # connect to an AP
    wlan.ifconfig((ip,netmask,gateway,dns))
    while not wlan.isconnected(): # wait till we are connected
        print('.', end='')
        time.sleep(0.1)
    print()
    print('Connected:', wlan.isconnected())
else:
    print("Already connected!")
