https://devzone.nordicsemi.com/f/nordic-q-a/5706/what-is-the-cpu-blocking-period-s110-and-nrf51822hi!, I am configuring connection interval time is 7.5ms , and slave latency is zero.and every connection interval event I am sending 1 packets (and my data lenth is only 3 bytes). if I will increase connection interval time than what happened ? en-USTelligent Community 13Tue, 24 Feb 2015 11:48:39 GMThttps://devzone.nordicsemi.com/thread/19976?ContentTypeID=1Tue, 24 Feb 2015 11:48:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:86650d61-df7d-47bf-87c5-f7adbf16f7beHung Bui<p>Hi Twinkal,</p> <p>As pointed <a href="https://devzone.nordicsemi.com/question/30307/timer2-not-working-properly-for-1ms-interrupt-with-sd-enable/">here</a>, the interrupt latency (CPU blocking period or the delay of the interrupt handler) depends on the number of packets per connection event (the period that the radio is active to send and receice packets.</p> <p>Since it&#39;s more about how long the radio is active per connection event, it doesn&#39;t mater what&#39;s your connection interval is. In your case, if you send 1 packet per event, the interrupt latency could be maximum 1180us (Table 30 in S110 Softdevice Spec).</p><div style="clear:both;"></div>
