Hi
Which CPU do you use and how much free RAM do you have?
Ethernet frame size is 1514, how is your PBUF_POOL_BUFSIZE size?

1. Check whether you have free these 20kB heaps and even try to increase it
for testing.
2. Change the authentication type from RSA to ECDSA, now you are using it
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, try change to
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 or similar.

Hi
I use from 3 years Lwip and http server and it works well. I have some xml
file on serwer with browser GET by js script.
Now I want to add TLS to http and I use mbedTLS library.
The problem is that every download of an xml file is a new http(tcp)
connection and that's what the new TLS negotiatio

I read this form "httpd_opts.h" file :

first STM32F107 but now GD32f107 is most the same but has more RAM
(96KB) and speed is 108Mhz.
LWIP current with repo
mbedtls-2.11.0.

Hi
I have set:
#define LWIP_HTTPD_POST_MANUAL_WND 1
In normal http:
if *post_auto_wnd=1 its work ok, i can read large file.
if *post_auto_wnd=0, not work (I see TCP ZeroWindow flags).
When i run https it not work and It doesn't matter if
*post_auto_wnd=0 or *post_auto_wnd=1. In wireshark i see

Did anyone have a problem or could check how the https(mbedtls) server
works when receiving data volumes larger than TCP_WND?

Send GET or POST from for example; curl -q -X POST --data-binary
"@test.txt" -k https://192.168.1.100
when test.txt file has more data than your TCP_WND

Hi
I use mbedtls with LWIP but without FreeRTOS.
I used GD32f107 with 96KB RAM, flash used by mbedtls is about 60KB.

Propably you have some delay time in connection function, when you

What processor do you have, do you have enough RAM?
How do you turn off DEBUG problem occurs?
When the browser downloads each file, a new connection is made, which
consumes RAM. Process httpd for a permanent connection which is only
one handshake.
