Is a work around available?

[igrr]

Ouch! https://github.com/igrr/axtls-8266/blob/324c2fdade3f39b4c7fb7fbe707f4a313023ecd3/ssl/tls1.c#L1425 😧
I'll fix that and another related issue soon.

[ghost]

Ok, I'll wait patiently.

[igrr]

@MarcusF2015 could you please try with the latest git version?
Thanks.

[mkeyno]

hi @MarcusF2015 which library did you use , last stable or staging ?

[igrr]

As mentioned at the top of the OP, Core Version: 2.1.0 — that's the latest stable version.

[mkeyno]

dear @igrr I've just update my library to this new library , is there any new library soon?

[ghost]

@igrr Thank you very much for your high speed software maintenance.
Now I have got a stupid problem: How to switch to the latest git version with Arduino IDE on a Windows PC? readme.md desribes this only for Linux.

OK.I have cloned the arduino-master git version to my user path and stolen the toolchain from 2.1.0 installation before removing and moved missing files to right directories. Built without error messages.
Now I'm collecting the serial data from ESP and after some hours I'll try to count exceptions (My hope: zero :) )

[igrr]

On windows you can open tools directory and double-click get.py script, if you have python installed.

[ghost]

Now it runs 9 hours nonstop without an exception!
And 13 hours, I think it works.
Thank you!

[ghost]

The issue is back. Sometimes there is a restart with exception 28:

I had some problems with file transfer.

[igrr]

Is this the same sketch? If not, could you please upload the sketch which may be used to reproduce this?

[ghost]

Sorry! I have confused the sketches. It is a similar sketch, but I will test the sketch above later and report.

Now the data from the sketch above (posting #1708 (comment)) :
