If you use an official micropython build, uasyncio is already on it.

If you use a daily build, you have to cross compile and copy it onto the device.

Websocket's: Websocket's require a lot of extra overhead for an arduino. Arduino? I thought this was about having esp8266? We need a solution that cares for this "running out of controll" part... This is quite easy, you just have the car expect one command every second. If it does not receive one, ...

Personally I'd use TCP to make sure the commands arrive at the car because with UDP you might end up losing "left" from a command series of "left, forward" in short succession and the car would go forward instead of left and forward but it depends on your implementation. If you send the signal very ...

I also noticed the performance hit on the esp8266 when using

That is awesome! Glad we finally get 1.10!

You should feed the hardware WDT when the esp is running and disabled it before deep sleep if it supports it.

No you can't work with anything on the esp8266 while in deep sleep. That's why it's called deep sleep.

That is true. Did not catch that. I'd try running it with a socket.close() statement before trying anything else. As you say it is "crashing" I assume it resets itself? This can happen with unstable power supply or just occassionally with the cheap NodeMCUs. Have those too. Does not happen that ofte...

What hardware are you using? I did not look at the code too closely but looks good to me though. The isr is short and should always work.

Try to catch the exception and write it to a file so you can look it up after a crash. Just resetting the esp won't give you much information.

That's a basic python problem. I recommend reading tutorials.

The solution however is to do this:
