CONFIG_DOWNLOAD_CLIENT_HTTP_FRAG_SIZE_2048=y

it could not helped me.

Please help me in investing the issue.

Hello Praveen, 

Please help me in investing the issue.

The modem has an internal TLS stack size limit of 2kB, see its release notes. I assume that this is the reason causing the socket error.

*** Limitations
***************
- TLS/DTLS
    ...
    - 2kB secure socket buffer size.

To confirm this, I would start with downloading files of smaller size.  

Cheers, 

Markus

Hello Markus,

Thank you for your time and reply.

Can you please tell me how to overcome this warning?

[Praveen Deshmane]

Hello Markus,

I have solved this problem by changing fragment size 2048 to 1024 in fota_download_start method

ret = fota_download_start(CONFIG_DOWNLOAD_HOST, CONFIG_DOWNLOAD_FILE, 42, 0, 1024);
if (ret != 0) {
	LOG_DBG("fota_download_start() failed: %d", ret);
} 

prj.conf

# Download client
CONFIG_DOWNLOAD_CLIENT_STACK_SIZE=4096
CONFIG_DOWNLOAD_CLIENT_BUF_SIZE=2048
CONFIG_DOWNLOAD_CLIENT_HTTP_FRAG_SIZE_1024=y
CONFIG_DOWNLOAD_CLIENT_RANGE_REQUESTS=n
CONFIG_DOWNLOAD_CLIENT_LOG_LEVEL_DBG=y
CONFIG_DOWNLOAD_CLIENT_LOG_HEADERS=y

and by adding above configuration of download client in prj.conf

if fragment size is 2048

fragment + HTTP header = will be too big for the modem to receive.

reducing the fragment size to1024 solved my problem.

Thanks and Reagrds
