I broke wifi by allocating a _thread lock (PICO W)

[GM-Script-Writer-62850]

if i disable thread_lock=_thread.allocate_lock() i am able to print my ip address, with it there it hard locks when i try to print the ip address

#!/usr/bin/python3
import time
from threadsafe import Message
import _thread
import uasyncio
sleep=uasyncio.sleep
sleep_ms=uasyncio.sleep_ms

class cross_thread:
	thread_lock=_thread.allocate_lock() # this line results in breakage somehow
	uasync_lock=uasyncio.Lock()
	data={}
	def reply():
		cross_thread.data["msg"].set(cross_thread.data["fn"](*cross_thread.data["args"], **cross_thread.data["kwargs"]))
		cross_thread.thread_lock.acquire()
	async def unblock(fn,*args, **kwargs):
		msg = Message()
		await cross_thread.uasync_lock.acquire()
		cross_thread.data={

		cross_thread.thread_lock.release()

		print("message=",msg)
		cross_thread.uasync_lock.release()

You can use uasyncio.sleep() instead of time.sleep() in the WiFi connection loop to ensure that the WiFi connection check doesn't block the event loop.

[GM-Script-Writer-62850]

in this example uasyncio is running on core 1, you can't connect to wifi from core 1 on a pico w

i have a uasyncio version:

async def wifi():
	from wifi_auth import ssid, password
	import network

	wlan = network.WLAN(network.STA_IF)
	wlan.active(True)
	wlan.connect(ssid,password)
	#wlan.config(pm = 0xa11140)# Power management is very very bad, ping time is around 1000x worse and packet loss insane (when running a server)

	while True:
		while True:
			wstat=wlan.status()
			if wstat < 0 or wstat >= 3:
				break
			print('Waiting for WiFi connection...')
			await sleep(1)

		if wstat == 3:
			status = wlan.ifconfig()
			print('Wifi Connected; ip =',status[0])
			while wlan.isconnected():
				await sleep(30)
		else:
			print("Failed to connect to wifi")
