CONFIG_MBEDTLS_CONFIG_C does not work

[Earthworn1]

Hi, 

I m building the Anjay LwM2M Client für the nrf9610 with MbedTLS as Security Backend. I got an issue with the the DTLS Handshake. I tried to enable MbedTLS Logging Informations with

CONFIG_MBEDTLS_DEBUG_C

CONFIG_MBEDTLS_DEBUG_LEVEL

I dont get any further Logging Informations. I found out that in mbedtls_debug_print_msg() ssl->conf_f_dbg is 0 and the message isn't printed.

Where do i have to set this to what?

Hi,

As far as I know, the nRF Connect SDK has no good way to configure logging for MbedTLS.

I usually debug this using the "hard way" of adding "printk" incrementally "deeper" into the MbedTLS code until I find where the error comes from.

I know this is not an optimal solution,
but will it work for you?

I recently got the word that we are working on this.
