https://devzone.nordicsemi.com/f/nordic-q-a/52448/thread-certification-neededIf I were to design a product using nRF52840 &amp; Thread. Normally, I would have to certify the product with the thread group and become a member.

Strictly you are reaping the harvests&nbsp;of the development and great work done with each Protocol as much as anyone, it would only be logical if you were to contribute towards further development and interoperability work.</p> <p>If you want to avoid these fees, we have <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/examples_nordic_prop.html?cp=5_1_4_9">proprietary radio&nbsp;protocols</a> as well as a <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/wireless_uart_15_4.html?cp=5_1_4_7_0">802.15.4&nbsp;MAC library</a> which you can use without having to worry about certification with any group or organization.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
