https://devzone.nordicsemi.com/f/nordic-q-a/80586/trouble-interfacing-between-nrf5340-and-nrf24l01-using-esb-enhanced-shockburstHi, I am trying to interface NRF5340 and NRF24L01+. I am using the default esb PRX code in the SDK and changed the receiving address to uint8_t base_addr_0[5] = {0xE7, 0xE7, 0xE7, 0xE7, 0xE7}; The NRF24L01+ works fine when I interface it with anotheren-USTelligent Community 13Thu, 14 Oct 2021 00:49:59 GMThttps://devzone.nordicsemi.com/thread/334018?ContentTypeID=1Thu, 14 Oct 2021 00:49:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:93ec8d98-5733-4f2c-85fe-0ef88e5e8783Anthony Shivakumar<p>Perfect! I got it working. The CRC I needed to set. Also, the address needs to be left at 4bytes as&nbsp; the prefix is added to the address.</p> <p>Thank you!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/333962?ContentTypeID=1Wed, 13 Oct 2021 13:32:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e09a3d23-64c7-47f5-a636-f7cabd3adfb5H&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>The PRX example is setup with the equivilant to EN_DPL and DYN_ACK in nRF24L01+, as well as 16 bit CRC, listening on RF channel 2 (ie. 2402 MHz) etc:</p> <p><a href="https://github.com/nrfconnect/sdk-nrf/blob/master/samples/esb/prx/src/main.c#L148-L154">https://github.com/nrfconnect/sdk-nrf/blob/master/samples/esb/prx/src/main.c#L148-L154</a></p> <p>&nbsp;</p> <p>You need to match the settings on both ends to make the communication work.</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
