Inquiries about the communication modulation method of nRF24L01 and the security of ESB Protocolhttps://devzone.nordicsemi.com/f/nordic-q-a/126428/inquiries-about-the-communication-modulation-method-of-nrf24l01-and-the-security-of-esb-protocolIn the process of obtaining DNV approval for products equipped with modules including nRF24L01+, I have some questions about wireless communication. 1. Does nRF24L01+ meet the wireless communication system specifications specified in IACS URE22? 2en-USTelligent Community 13Thu, 08 Jan 2026 10:12:25 GMTRE: Inquiries about the communication modulation method of nRF24L01 and the security of ESB Protocolhttps://devzone.nordicsemi.com/thread/558245?ContentTypeID=1Thu, 08 Jan 2026 10:12:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5025257e-02e0-4c88-b229-786664dbec06ketiljo<p>The nRF24L01+ is a transceiver only, the &quot;protocol&quot; (ESB) it has is very limited. The functionality purely depends how it&#39;s implemented and controlled by the host MCU. ESB can only do packet acknowledge and re-transmitting of lost packets, any other functions are controlled by the host MCU.&nbsp;</p> <p>You must direct these questions whoever that owns and has designed the system.</p><div style="clear:both;"></div>
