pyserial
writer doesn't write anything
Hello,
When i was trying to send a data with following code nothing happens:
from asyncio import get_event_loop
from serial_asyncio import open_serial_connection
async def run():
reader, writer = await open_serial_connection(url='/dev/ttyUSB1', baudrate=115200)
writer.write(b'Hello World')
loop = get_event_loop()
loop.run_until_complete(run())
But when i want to read and write everything works perfectly. Is there any way to write only async serial.
Have a great day :)
How do you now that nothing happens?
The message is send to /dev/ttyUSB1 and should the device do something when it receives b'Hello World'?
Is there some physical response or lack of that?
I had an arduino connected on /dev/ttyUSB1 and if it receives any data (if(Serial.available()>0)) it has to blink. So nothing blinks.
I solved problem with write than read structure. But still nothing works with only write structure.
