https://devzone.nordicsemi.com/f/nordic-q-a/62043/crc-32-with-enhanced-shockburst-radioHi dear Nordic Team I&#39;am currently implementing a 802.15.4 compliant ShockBurst Radio TX/RX module on the NRF52811. As far as I understand there is a crc 16 implemented in the nrf_esb library but nothing further is this correct? If so what would been-USTelligent Community 13Tue, 02 Jun 2020 12:37:07 GMThttps://devzone.nordicsemi.com/thread/252736?ContentTypeID=1Tue, 02 Jun 2020 12:37:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b1b958b8-c06d-4063-9afe-ce1e9f99d600atthorv<p>Thank you Kenneth for your answer and clarification.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/252734?ContentTypeID=1Tue, 02 Jun 2020 12:33:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:60098286-4c10-4958-9bfd-8b588c83896eKenneth<p>The hardware support up to 24-bit by setting the NRF_RADIO-&gt;CRCCNF register to 3:<br /><a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/radio.html#register.CRCCNF">https://infocenter.nordicsemi.com/topic/ps_nrf52840/radio.html#register.CRCCNF</a></p> <p>If you need longer CRC than this, then you would need to implement this in software, e.g. that the last 4bytes of the payload is a CRC calculated value that you need to manually calculate and verify on reception.</p><div style="clear:both;"></div>
