https://devzone.nordicsemi.com/f/nordic-q-a/29768/ant-licenseDoes the nRF51422 require a license from ANT for use? Their website specified that it is not for dedicated hardware but might be for multi-protocol devices.

From <a href="https://www.thisisant.com/developer/components/view-all-components/nrf52-ant-stack-licensing-faq">www.thisisant.com/.../nrf52-ant-stack-licensing-faq</a> they state that &quot;What are the royalty fees for commercial use of the ANT stacks? The royalty fee with a commercial agreement will be $0.08 USD per instance of the S212 or S332 ANT stack within an item that is sold, rented, or leased.&quot; In other words, ANT is also royalty-based.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/118000?ContentTypeID=1Thu, 05 Mar 2015 13:11:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1f3ec267-cf88-4272-b47c-b7b7c4eae7a1Asbj&#248;rn<p>ANT license is required if you want to make ANT+ parts. For using standard ANT channels (Not ANT+) there&#39;s no fee. Would recommend you to contact ANT through their website regarding this as well to be sure that you get the best answer for your specific application.</p><div style="clear:both;"></div>
