https://devzone.nordicsemi.com/f/nordic-q-a/51391/nrf-sniffer-hardware-choiceHi, I see your web: https://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF-Sniffer#infotabs There are 4 hardware (DK x 3, Dongle x 1) we can choose to used as nRF Sniffer hardware. As for sniffer function, do they capture same BLE packetsen-USTelligent Community 13Tue, 27 Aug 2019 08:28:43 GMThttps://devzone.nordicsemi.com/thread/206268?ContentTypeID=1Tue, 27 Aug 2019 08:28:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:626c4f39-5d11-404a-9bea-75c67386ed80Heidi<p>Hi Charles!</p> <p>There are a few differences in which HW you use as a Sniffer.</p> <p>You are correct in that the nRF52 DK supports Bluetooth 5, which the nRF51 DK does not, so the nRF51 DK will not be able to capture BLE packets sent over Bluetooth 5. Additionally, while the SoftDevices in nRF51 are being maintained, no new updates will be released.</p> <p>The nRF51 does not support LE 2M PHY mode, while the 52 does. Long range or coded phy is not supported in the 51 or the 52.</p> <p>The 52 sniffer also uses a much faster UART implementation so has less dropped packets when sniffing high bandwidth connections.</p> <p></p> <p>I hope this helps with your selection.</p> <p></p> <p>Best regards,</p> <p>Heidi</p><div style="clear:both;"></div>
