Support Status for CoAP over DTLS for NRF9160 MFW

ubieda

Hello everyone,

I'm reaching out to touch base on the current support status on the latest software (MFW v1.3.1 and NCS v1.7.1) for CoAP over UDP (DTLS) for using as a main connectivity protocol.

Is it a suitable approach for production, or only prototyping stage?

How would you compare it, in terms of robustness, to the current implementation of MQTT over TLS?

Thanks in advance!

Luis.

    Hi,

    First of all, the CoAP and DTLS/UDP layers are sepparated. CoAP is implemented in a library in Zephyr, while the DTLS and UDP stack are implemented in the modem.

    That said, I don't know of any reason for why the CoAP library shouldn't be used in production.

    And the modem with it's UDP and DTLS stack are already used in production by many customers without any problems.

    Best regards,

    Didrik
