Led blinking function:

async def blink: 
  while True:

use an asyncio.Event e.g.

async def main():
    wifi_connected = asyncio.Event()

    async def connect_to_wifi():
        led.on()
        await ...  # do connection stuff
        wifi_connected.set()

    async def wait_for_connection():
        await wifi_connected.wait()
        led.off()

    await asyncio.gather(connect_to_wifi(), wait_for_connection())

asyncio.run(main())
