 We have a test setup that consists of an application running on an Android device (BLE central) collecting data from a BLE peripherial device (with a Nordic Nrf51822 chip).

&lt;p&gt;Can you create a new ticket for your question?&lt;/p&gt;
&lt;p&gt;This ticket is already 4 years old,&lt;/p&gt;

&lt;p&gt;documentation talks about packet error rate but it&amp;#39;s not working with Bluetooth stack its running on it&amp;#39;s own. what&amp;#39;s my problem is data link layer retransmit the malform packet so i need to count the retransmitted packet while running the Bluetooth stack operations is it possible?&lt;/p&gt;

&lt;p&gt;You can have a look at this blog, by observing the RX END event, the author managed to measure the packet error rate:&amp;nbsp;&lt;a href="https://jimmywongiot.com/2019/08/26/__trashed-5/"&gt;https://jimmywongiot.com/2019/08/26/__trashed-5/&lt;/a&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Suggestions for measuring Bit Error Rate across BLE connection</title><link>https://devzone.nordicsemi.com/thread/252602?ContentTypeID=1</link><pubDate>Mon, 01 Jun 2020 21:03:58 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:eefc3894-63d0-435a-963b-99c1c98764ee</guid><dc:creator>jvillapando</dc:creator><description>&lt;p&gt;Is there any update to this? We would like to do error rate testing as well, and I was wondering if this is the only solution.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Suggestions for measuring Bit Error Rate across BLE connection</title><link>https://devzone.nordicsemi.com/thread/61697?ContentTypeID=1</link><pubDate>Mon, 05 Sep 2016 11:03:29 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:3edb1c1b-026f-4043-a587-895cca305736</guid><dc:creator>Hung Bui</dc:creator><description>&lt;p&gt;Hi Apolcari,&lt;/p&gt;
&lt;p&gt;The number of packet error (CRC error for example) or retransmission are not available for the nRF51 application and also on the app on Android, as far as I know.&lt;/p&gt;
&lt;p&gt;What you can do is to use a sniffer to track the connection and count the number of re-transmission or CRC error.&lt;/p&gt;
&lt;p&gt;Beside the ready to use &lt;a href="https://www.nordicsemi.com/eng/Products/Bluetooth-Smart-Bluetooth-low-energy/nRF-Sniffer/"&gt;sniffer&lt;/a&gt;, we also provide in the .zip package the SnifferAPI (SnifferAPI.zip) so you can build your automation test tool.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
