https://devzone.nordicsemi.com/f/nordic-q-a/64899/nrf52840-as-ble-sniffer-pca-10059I need BLE sniffer and I puchase this device because in this manual of &quot;nRF Sniffer&quot; say that &quot;nRF52840 Development Kit (PCA10056) &quot; is compatible. https://infocenter.nordicsemi.com/pdf/nRF_Sniffer_BLE_UG_v3.1.pdf I get device, but my nRF52840en-USTelligent Community 13Tue, 18 Aug 2020 08:01:16 GMThttps://devzone.nordicsemi.com/thread/265004?ContentTypeID=1Tue, 18 Aug 2020 08:01:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:39ddf44c-ffd0-4903-8172-93197fed8600Simonr<p>Hi</p> <p>That is correct. The nRF52840 Dongle (PCA10059) does not support the nRF Sniffer for BLE firmware. <a href="https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Sniffer-for-Bluetooth-LE">As stated on the product page</a>: To use the nRF Sniffer for Bluetooth LE you need either the nRF52840 DK (PCA10056), nRF52 DK, nRF51 DK, or the nRF51 Dongle.</p> <p>You can use the nRF52840 Dongle as a <a href="https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Sniffer-for-802154">sniffer for 802.15.4 protocols</a>, like Thread and Zigbee for instance, but not for BLE.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
