SSL DOWNLOAD EXAMPLE
Description:
Download file from Web server via https.
Configuration:
Modify SERVER_HOST, SERVER_PORT and RESOURCE in example_ssl_download.c based on your SSL server.
Modify SSL_MAX_CONTENT_LEN in SSL config and configTOTAL_HEAP_SIZE in freertos config for large size file.
If the transmitted fils size is larger than 16kbytes, SSL_MAX_CONTENT_LEN should be set to 16384.
FreeRTOS heap may be increased for ssl buffer allocation.
(ex. If using 16kbytes * 2 for ssl input/output buffer, heap should be increased from 60kbytes to 80kbytes.)
[config_rsa.h]
#define SSL_MAX_CONTENT_LEN 16384
[FreeRTOSConfig.h]
#define configTOTAL_HEAP_SIZE ( ( size_t ) ( 80 * 1024 ) )
[platform_opts.h]
#define CONFIG_EXAMPLE_SSL_DOWNLOAD 1
