I found that changing the TCP_MSS size, increasing it, solve this specific message error but then I still have another issues. So it looks there is some relation on the TCP_MSS and TLS
My relevant defines are: #define TCP_MSS 1024 #define TCP_WND (16 * TCP_MSS) #define MBEDTLS_SSL_MAX_FRAGMENT_LENGTH 1 #define MBEDTLS_SSL_MAX_CONTENT_LEN 4096 #define MBEDTLS_ECP_WINDOW_SIZE 7 -- Sent from: http://lwip.100.n7.nabble.com/lwip-users-f3.html _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
