DTLS and carrier library

Hi,

The modem uses both the DTLS sockets available, so there are no left for the application.

"The LwM2M carrier library uses both the DTLS sessions made available through the modem. Therefore, the application cannot run any DTLS sessions."

Best regards,

ok, thanks. 
So, If I am using carrier library (for carrier certification) then I have to use mbed TLS for the DTLS in my application. Correct?

Thanks

Yes.

Or, you must find a way to make do without DTLS, e.g. just UDP or TLS/TCP.

Though, I don't know how well Zephyr handles some socket using offloaded DTLS and some using native DTLS.

Thanks! 
One question

offloaded DTLS

Can you please check how to offload? or point to the code that allow to have some DTLS socket in the modem and some native in mbedTLS?

Thanks

beside this, how many modem TLS socket are left, if the carrier library takes both modem DTLS?

Thanks
