ESP32 issues about duino-coin HOT 10 CLOSED

In case someone want the code I'm running here it is. It seems to be working great without any bad shares or close to zero for long runs. I have added WiFiMulti reconnection too. Btw, I have changed the baudrate too, it's 500K, the ESP32 can handle that speed nicely.

Really nicely explained! We will try to make use of these tips, @JoyBed should also take a look

Great! I hope it helps.

By the way there is a couple of things that I forgot, one is the flushing of the client, this should be done before sending any request to the server and after the reading of the buffer. Doing it like this would help preventing the mixing of messages (for example the server version could be merged with the actual job causing a bad share).

Yesterday I was making some tests and find out that there were a lot of bad shares, I was thinking that maybe it was the esp_sha function but playing with the yield and some delays I found out that somehow the esp_sha need some wait time before and after execution, I don't know why it behaves like that but when I put some delays before and after suddenly there were not one bad share. And it didn't affect the hashrate, the delays I use are 10 microseconds before and after each esp_sha call.

Finally another suggestion is to stop using the delay functions, I think the RTOS handles that well on the background, but this is just for the ESP32, it's a little bit messy to use the delay function on a task. This is somewhat of an opinion more than a fact actually haha.

Will be looking forward to any change in the future.

Tried your new code and it dies after several minutes every time, not sure why as I'm not saving the serial output.

I will post it without WiFiMulti, I think is making the code crash.

Try this one. I didn't remove the WiFiMulti (it is quite useful) I have change some lines and I think it works but let me know if you have some problems.

By the way, the server will always close the connection from time to time (could be several minutes or some hours), I think this behavior is expected and after that it should connect immediately. What it should not be expected is to disconnect from WiFi or don't connect to WiFi at all.

Ok, what do you see on the serial monitor? Is it connecting to WiFi or not connected at all? I think that code I posted had some issues with some boards and also I don't like it very much that's why I didn't put a request. Nevertheless I have requested a code change now, maybe you can try that code instead. Here it is:

I believe I have implemented all of these optimizations already on the latest version. Will close it now.
