Assumes there is an existing STM project with native LwIP support. wolfSSL needs to be compiled with the macro WOLFSSL_LWIP_NATIVE
The main function to call in the example code is tls_echoclient_connect();
Macros in lwipopts.h were also adjusted to better handle TLS packets, which can be as large as 16k. The macros adjusted were:
- MEM_SIZE(16*1024)
- MEMP_NUM_PBUF (10 -> 20)
- PBUF_POOL_SIZE (8 -> 9)
- PBUF_POOL_BUFSIZE (512 -> 2048)
- TCP_WND (2TCP_MSS -> 11TCP_MSS)
To start up a server for the example client to connect to use the bundled wolfSSL example server on a desktop:
cd wolfssl
./configure && make
./examples/server/server -b -d -p 11111 -c ./certs/server-ecc.pem -k ./certs/ecc-key.pem -i
