So those steps are coming from standart definitions only, not from HW.</p> <p></p> <p>Regards,</p> <p>Eugene</p><div style="clear:both;"></div>https://test-devzone.nordicsemi.com/thread/372403?ContentTypeID=1Tue, 14 Jun 2022 13:17:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:40561a67-b133-4a8d-956f-a9c46db04cc8user93921<p>Hi Eugene,</p> <p><span>IEEE 802.15.4 is not just about the radio frequency range, you need to operate on defined channels. Every channel has its own band.</span></p> <p><span>Best regards,</span></p> <p><span>Charlie</span></p><div style="clear:both;"></div>
