long running webserver not reachable

[jedie]

I have a problem to run a webserver on SonOff S20 (ESP8266EX) -> https://github.com/jedie/micropython-sonoff-webswitch

I used the official esp8266-20190529-v1.11.bin firmware.

I start with a simple socket.socket() webserver see e.g.: https://github.com/jedie/micropython-so ... ain.py#L86

Now i use asyncio.start_server() e.g.: https://github.com/jedie/micropython-so ... ch.py#L154

In both cases: The long running webserver is not reachable at some point. I still see the IP connected. But the server is not responding.
I implement a own watchdog that will reconnect to WiFi station if disconnected.

Anyone a tip what it might be?

Another question: How can I implement a watchdog that monitors the correct functioning of the webserver?

You can try:

Code: Select all

import esp
            esp.sleep_type(0)

In our mqtt tests the esp8266 did quite poorly when the wifi signal was weak but this improved the stability a lot.

Of course it could be the case that you have a completely different problem like your webserver crashing, but I can't say anything about that.

Thanks. I tested esp.sleep_type(0) but without success.

I monitored the output via shell: My watchdog is running and it is still connected to WiFi station.

I think the actual web server must have stopped at some point.

The question is: How can I test if the server is still running?

It seems that I'm wrong: It does helping

Is the sleep_type() setting persistent like the connection and debug settings?

ie. You only need to execute the commands once and the ESP8266 remembers the value even after a reboot.

[kevinkk525]

No you have to set it every time as it falls back to its default value.

I added it to my "boot.py"

Think i found a way to "watchdog" the web server:

Feed the watchdog from main asyncio loop. If the loop stops: web server stopped.
