using serial port in python3 asyncio

Question

i\'m trying and, so far, failing to use python asyncio to access a serial port.

i\'d really appreciate any tips on using the new python async framework on a simple fd.

Answer 1

Here is a working example using pyserial-asyncio:

from asyncio import get_event_loop
from serial_asyncio import open_serial_connection

async def run():
    reader, writer = await open_serial_connection(url='/dev/ttyS0', baudrate=115200)
    while True:
        line = await reader.readline()
        print(str(line, 'utf-8'))

loop = get_event_loop()
loop.run_until_complete(run())
