Hi Billy,

thanks for the reply. I still have to clean up the driver a bit, then I will create the PR.

With regard to the second message, thanks for the hint. I have already stumbled upon these commands, but according to the manual they are specific to Huawei's IoT platform, which I don't use. I have the impression that it's based on LwM2M, but I would like to be able to use DTLS encryption regardless of the protocol I use (UDP, TCP or the higher level COAPS or LwM2M).

That's why I'm looking for a way to use Zephyr's mbedtls with my offloaded sockets. Any help would be very much appreciated :-)

All the best,

Holger
