CoAP w/ DTLS and MQTT w/ TLS

I am trying to do some research involving benchmarking CoAP w/ DTLS and MQTT w/ TLS performance. I was hoping to be able to do these tests on a constrained device (<50 KB RAM) with WiFI integrated.

I was hoping to use either the:

  2. Adafruit Feather Huzzah WIFI

However, after looking online it seems their WIFI does not support DTLS. Does anyone know if it is possible to run CoAP w/ DTLS and MQTT w/ TLS on either of these development boards?

If not, does anyone have any suggestions of constrained development boards that support running these protocols?

Would using Ethernet instead of WiFi make this project easier to achieve?

Thanks for your help!
