https://devzone.nordicsemi.com/f/nordic-q-a/24364/packets-per-connection-interval-from-nrf-sniffer-logHi! Thanks for this post blog and question on sniffer logs . However, I am not clear on how to calculate the number of packets sent every connection interval? Please clarify. In my case, the connection interval is 10ms and I transmit the followingen-USTelligent Community 13Tue, 15 Aug 2017 16:39:50 GMThttps://devzone.nordicsemi.com/thread/95928?ContentTypeID=1Tue, 15 Aug 2017 16:39:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a123e388-e701-4f09-ad45-816f25e77654endnode<ol> <li>Connection interval is extended by More Data (MD) bit in LL PDU header. <a href="https://github.com/Szarp/WolfsHeart/blob/master/Documents/Low%20Energy%20Training.pdf">See slides 115, 122 and 123 here</a>. So by looking at MD bits and time-stamps you need to count it yourself. Yes, time-stamps on Nordic sniffer with Wireshark aren&#39;t very accurate, that&#39;s what you get for $40, anything better costs you $1k-$30k (depending on brand and other capabilities).</li> <li>Only you know what data are going over your link so it&#39;s only you to tell which data are which. If you use different GATT Services/Characteristics to transport these then it is easy but even with single GATT &quot;tube&quot; it should be trivial to define some reasonable protocol how to decode data transported over.</li> </ol><div style="clear:both;"></div>
