MicroPhyton Wifi assistance with Pico Pi W
I am super new to programming with MicroPyton. I watched a couple viddeos on circuit python as I wanted to get my Pico Pi W connected via bluetooth to be able to contorl the LEDs I attached to it. Come to find out that Circuit Python does not support bluetooth even though the Pico Pi W supports it. I was told that I would need to most likely use CircuitPython as its similar but should get the job done. I was looking and I couldnt find any code or something that would allow me to connect via bluetooth, but I did find a wifi connect code. My code lets me connect to a wifi network (as long as I know the SSID and password) I can then connect to if by surfing to the IP address the Pico picks up. It will project a very basic html page with buttons on it that will allow me to statically change the the color. I can change it from red to blue to green and then off. When i try to make it run an animation of sorts (needs to be in a loop to do so, at least my very little knowledge tells me I need to do so.) it seems to disconnect from the wifi connection(at least stop broadcasting itself) and not allow me to change colors back to a static color or even off. I have to either disconnect the power to the board/manually stop the program from running in Thonny. I will paste my code below to see if anyone can help.
import network
import socket
import machine, neopixel, random, math, time
from time import sleep
from picozero import pico_led
p = machine.Pin.board.GP0
n = neopixel.NeoPixel(p, 30)
ssid = ''
password = ''
def connect():
#Connect to the WLAN
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect(ssid, password)
while wlan.isconnected() == False:
print('Waiting for connection...')
sleep(1)
ip = wlan.ifconfig()[0]
print(f'Connected on {ip}')
return ip

#Open a socket
address = (ip, 80)
connection = socket.socket()
connection.bind(address)
connection.listen(1)
return connection

I do want to try and get this swapped over to bluetooth and use a bluetooth compatible app on my cell phone (iPhone 15) to connect instead of wifi as I would have to run a hot spot to get it to connect while out and a bout with my prop. Can anyone lend some assistance on this please and thank you in advance!
Regards, Andrew
I have tried to eliminate the loop but if I do then it becuase just a static xmas color (alternating red green) when its supposed to swap randomly between the two colors looking like xmas lights. I have tried adding break statements but they dont seem to work. I am not sure what exaclty I am doing wrong.
