https://devzone.nordicsemi.com/f/nordic-q-a/3811/is-nrf8001-interoperable-with-nrf24l01-deviceHi, I would be grateful if someone could guide me a bit. As far as I understand, nRF24L01+ implements Enhanced Shockburst technology in chip. To use nRF8001 as drop in replacement, an application controller should implement ESB/Gazell in software, een-USTelligent Community 13Thu, 18 Sep 2014 09:22:55 GMThttps://devzone.nordicsemi.com/thread/13760?ContentTypeID=1Thu, 18 Sep 2014 09:22:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:21a4b5ae-d315-4f14-8d3f-c3bd600cb8f9H&#229;kon Alseth<p>Hi Matej,</p> <p>Unfortunately, the nRF8001 is a bluetooth low energy connectivity device only. You do not have direct access to the radio PHY, so it&#39;s not possible to develop a dual protocol (BLE + ESB) with only the nRF8001. The nRF51x22 is the only device that can do multi-protocol (BLE and ESB/GZLL or ANT)</p> <p>Cheers, Håkon</p><div style="clear:both;"></div>
