I don&#39;t see any reasons why you should not be able to use it with W5100 and the MQTT library, but I do not have any examples or details on how to implement this. I suggest you read the <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.1.0/lib_iot_security.html?cp=4_0_0_3_23_1_11">library details</a> in the documentation and on <a href="https://github.com/ARMmbed/mbedtls">mbedtls</a> to get started.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
