Re: [lwip-users] alttcp_tls_mbedtls problems setup a server, "unexpected message"

You have strong uP. Time between client hello and server hello shuld be about 0.1s. I have stm32f107 and my time is about 1.2s with RSA nad 0.8 with EC.

Hi Tomek,
I'm using STM32F756ZG, 216Mhz, 320K RAM
there is also some difference when running in debug (slow) or in release (faster)

Could lwIP detect duplicated transmissions and discard it?

Mario

I'm using lwIP 2.1.2 trying to setup a https server.
I'm getting an "unexpected message" fail error from the TLS connection,
I suspect that there is an ACK that appears out of order,

I left here some logs:
https://pastebin.com/raw/K8DJYMYW
https://pastebin.com/raw/qyJtdf0X

I read on other old posts that there was some possible related starvation
issues but I don't know it was already solved.

I noticed that my systems hangs and take about 10 seconds to reply to the
"Hello client message" and then, it sends some previous acknowledges. It
does not sounds good to me and maybe the cause of the error.

Any help how can I solve this?
