https://devzone.nordicsemi.com/f/nordic-q-a/32597/how-slave-latency-affects-the-data-sending-process-of-a-slave-deviceDear friends, If i set the conection interval=100ms and the slave latency=1, the slave will wake up every 200ms. If the slave has data to send, it will still wake up every 100ms. However, &quot;If the slave has data to send, it will wake up immediately&quot;en-USTelligent Community 13Thu, 22 Mar 2018 02:14:19 GMThttps://devzone.nordicsemi.com/thread/125433?ContentTypeID=1Thu, 22 Mar 2018 02:14:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5aed9961-c572-4283-9171-75e0b4e2e0ddxvhongpeng<p>thank u .</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/125317?ContentTypeID=1Wed, 21 Mar 2018 09:44:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:17493d99-2d6b-45a8-b671-d7a0df1fc3d9H&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>In your case, the slave will wake up and send in the &quot;nearest 100 ms slot&quot;, so the worst-case latency from you uploading the data to the stack to it being sent on-air is 100 ms.</p> <p>Slave latency will not wake up immediately and send on-air, it will conform to the connection parameters set for your bluetooth link.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Håkon</p><div style="clear:both;"></div>
