I am trying to run the example listed here
https://docs.python.org/3/library/async ... io-streams
which seems to me it should run in micropython
Code: Select all
import network
import machine
import utime as time
import uasyncio as asyncio
async def tcp_echo_client(message):
#reader, writer = await asyncio.open_connection( '127.0.0.1', 8888)
reader, writer = await asyncio.open_connection( '192.168.12.122', 8888)
print('Send: {}'.format(message))
writer.write(message.encode())
await writer.drain()
data = await reader.read(100)
print('Received: '.format(data.decode()))
print('Close the connection')
writer.close()
await writer.wait_closed()
def main():
wlan = network.WLAN(network.STA_IF)
ssid, paswd = open(wifi.txt, tr).readlines()[0].strip().split(,)
wlan.active(True)
wlan.connect(ssid, paswd)
t=time.ticks_ms()
while(not wlan.isconnected()):
time.sleep(0.25)
print(wlan.ifconfig())
asyncio.run(tcp_echo_client('Hello World!'))
if __name__ == __main__:
main()
This is the error I get in micropython
Code: Select all
