Hi, No, the Composite Observe feature isn’t supported in Zephyr yet. It’s a part of the LwM2M 1.1 specification which we don’t support at this point. We are planning to add LwM2M 1.1 support, but I do

Hi Brenton, The DNS server configuration shouldn’t be an issue in this case, as we provide the IP address of the server – in such case the DNS query isn’t even sent as we already know the IP address.

DTLS over CoAP for the Zephyr project
Nikos, CoAP over DTLS is supported, we just don’t have a straightforward sample of this functionality. For instance, the `lwm2m_client` sample uses CoAP protocol over DLTS (LWM2M uses CoAP internally)
