nRF9160 Downloading large binary HTTPS

[super153]

Hi all,

I am running into an issue where I need to download a large binary, but I am limited to the 2k recv buffer while utilizing TLS.

I can utilize the download client successfully when the binary is uploaded to a public AWS S3 bucket, but the issue occurs when I am trying to run it off of a private server.

I can do a HTTP 1.1 GET and recv the first 2k bytes (including header).

This server utilizes a MAC ID in the URI and a JWT authorization token (sent in the header).

Is there a way to customize the download client to be able to do this?  Or to even have a custom implementation with a stream of nrf_recv()?

Thank you in advance.

Hello,

have you tried using mbedtls on the app core to circumvent the TLS size limit? You can read Charlies response in this ticket; Link.

So is there some API implementation of an HTTP callback response for chunked octet streams?  Or does this have to be a complete custom implementation outside of the download client?

I am looking to avoid manipulating the toolchain files and keeping my code portable.

Running the mbedtls stack on the app core removes the TLS size limit entirely, so there is no need for chunked data at all.
