Dear Support-Team,
due to the 2KB limitation of the secure buffers of the nrf9160 modem I am trying to setup native tls. I found the https_client sample which sounded promising, but when I use the same configuration as described in the sample (prj.conf + overlay-tfm_mbedtls.conf) I get a "region FLASH overflow", so I am a trying to figure out which settings do what.
Using https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.5.0/kconfig/index.html does not help as the description gives no clue at all:
Examples:
CONFIG_NRF_SECURITY_ADVANCED
Advanced mbed TLS Configuration Settings
This configuration has no effect and will be deprecated. It is kept in to ensure projects setting this aren't affected.
or
CONFIG_TFM_PROFILE_TYPE_NOT_SET
TF-M build profile is not set
Is there any other documentation for those configurations?
Best regards
Context: I am working on a MQTT project and I have provisioned the certificates to the modem. With setting set_native_tls in the mqtt_sec_config struct I am able to connect to the server and get the data I expect (> offloading to the modem). Now I have to change to native tls in order to receive some other data which does not fit into the 2kB secure buffer of the modem.
