She also explains that this is often limited by the host to a maximum of 4 packets per connection interval. Also be aware that you need to use all bytes in the payload to achieve this data rate.</p> <p>To calculate the maximum data rate you need to find out which connection interval you are using, please see <a href="https://devzone.nordicsemi.com/index.php/knowing-the-connection-interval">this thread.</a> In addition, you need to find out if the is any limitation on packets per interval.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/4715?ContentTypeID=1Tue, 26 Nov 2013 12:37:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1bb856f6-d4e0-42f0-b87e-be5637a54115Bastiaan<ol> <li>i donno what connection parameters master use! but i specified mine and calculated on that!</li> <li>i am using notifications</li> <li>i know i am able to send only 6 packets per connection interval, but is it not possible to send 6 packets in one characteristic and 6 packets in another characteristic in the same connection interval?</li> <li>check this link - your employee only stated that ---<a target="_blank" href="https://devzone.nordicsemi.com/index.php/51822-bluetooth#reply-2936" rel="nofollow">https://devzone.nordicsemi.com/index.php/51822-bluetooth#reply-2936</a></li> </ol><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/4716?ContentTypeID=1Tue, 26 Nov 2013 12:37:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:caba140e-fdac-47d0-a8fc-53ec5fb21911Guest<ol> <li>i donno what connection parameters master use! but i specified mine and calculated on that!</li> <li>i am using notifications</li> <li>i know i am able to send only 6 packets per connection interval, but is it not possible to send 6 packets in one characteristic and 6 packets in another characteristic in the same connection interval?</li> <li>check this link - your employee only stated that ---<a target="_blank" href="https://devzone.nordicsemi.com/index.php/51822-bluetooth#reply-2936" rel="nofollow">https://devzone.nordicsemi.com/index.php/51822-bluetooth#reply-2936</a></li> </ol><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/4714?ContentTypeID=1Tue, 26 Nov 2013 12:26:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d79c094c-a5ac-40ae-a9d2-505c26032862Petter Myhre<p>The minimum and maximum connection interval only sets the boundaries, the master sets the actual connection interval, do you know what it is set to?</p> <p>How are you sending the packets? Are you using notifications?</p> <p>One packet from each characteristic every 1ms, you want to send 20 packets per connection interval? If it is 10ms?</p> <p>Where did you get 6 KBps(or 6 kbps) from, and is this effective data rate or on air data rate?</p><div style="clear:both;"></div>
