QUESTION
I am making a small webpage which controls a Microbit and shows some sensor data.
I am trying to implement asynchronous read and writes to the microbit through my flask backend based on the things I click on the front end.
But when I use flask to run a function I have it gives an error which says

Answered 2021-Aug-04 at 14:00The error indicates that there in no event loop in not MainThread, for async programs in Python we usually have only one asyncio loop in MainThread, we do not want more asyncio loops, since they'll be fighting each other for time and the whole app will be slower and more prone to errors.
If I were you I would use aiohttp or any other async http framework instead of Flask, otherwise use any other not async library for serial port.
But how you can get another loop in not MainThread if you want it? Please find example:

Install aioserial
You can use aioserial like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
