https://devzone.nordicsemi.com/f/nordic-q-a/3217/nrf-sniffer-antenna-tuningI&#39;m using nRF-Shiffer V 0.97 on a PCA10000 V2.2.0 Usb dongle. I see lots of helpful details. But the problem is, that the sniffer often misses parts of the communication. I have some automated Ble tests, were a Android central connects the nRF51822en-USTelligent Community 13Mon, 27 Oct 2014 11:21:51 GMThttps://devzone.nordicsemi.com/thread/11818?ContentTypeID=1Mon, 27 Oct 2014 11:21:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bef03655-f0b8-482a-ad71-dbdbba803f6eAsbj&#248;rn<p>I couldn&#39;t find the references to PCA10003 and PCA10028 in the sniffer user guide, but in general you will be better of to use the PCA10001 board with regard to antenna performance. I would also ask you to consider the placement of the board and make sure that you place the sniffer between the central and peripheral. Are you placing the central and peripheral far from each other? Do you have multiple centrals and peripherals close to your sniffer?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/11817?ContentTypeID=1Sat, 13 Sep 2014 22:42:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:577e2893-770c-43fc-b84c-fcbf4e0b0d8bJoe Merten<p>Ok. It will take a bit time, because I&#39;d currently switched to a different project.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/11816?ContentTypeID=1Sat, 13 Sep 2014 13:08:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0604052f-59fd-4f8b-977f-56c354d96d15David Edwin<p>The issue that you see is very unlikely to be due to antenna issues, can you switch to the latest version of the nRF Sniffer and let me know if the problem persists. If your problem persists, please post a trace of the sniffer logs so I can take a look at it.</p><div style="clear:both;"></div>
