https://devzone.nordicsemi.com/f/nordic-q-a/672/how-to-acheive-high-data-rateHi, Is there any difference(data rate) between sending large data packets through single characteristics and multiple characteristics? I have created one characteristic with notify property and also created a buffer of size 20 bytes(packet sizeen-USTelligent Community 13Tue, 26 Nov 2013 10:36:56 GMThttps://devzone.nordicsemi.com/thread/3399?ContentTypeID=1Tue, 26 Nov 2013 10:36:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:151db146-980e-4e3c-83d7-56e03702b4adBastiaan<p>yep, now i am also losing packets, i created two characteristics each with 20 bytes payload and connection interval of 10ms, i am trying to send each packet for every 1ms, then for 1s i am recieving 45 to 50 packets varying for every second but theoritically i hav to recieve 500 packets but not recieving</p> <p>in one case i am getting 30 packets of char.1 and 20 of char.2 and in other case the number is varying but i am not perfectly getting the all packets transmitting. some packets are lost</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/3401?ContentTypeID=1Tue, 26 Nov 2013 10:36:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b45cf04c-be33-42ee-aa6f-7bbf418cbe51Guest<p>yep, now i am also losing packets, i created two characteristics each with 20 bytes payload and connection interval of 10ms, i am trying to send each packet for every 1ms, then for 1s i am recieving 45 to 50 packets varying for every second but theoritically i hav to recieve 500 packets but not recieving</p> <p>in one case i am getting 30 packets of char.1 and 20 of char.2 and in other case the number is varying but i am not perfectly getting the all packets transmitting. some packets are lost</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/3398?ContentTypeID=1Tue, 26 Nov 2013 09:01:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:891eb77f-4d73-4e25-9551-4cc41288b5dfbalaji<p>As per the document i have referred, we can able to send 4 to 6 packets (each packet maximum of 20 bytes) in a connection interval. As shown in the attachment i too didn&#39;t get any idea how the minimum and maximum connection interval affect the throughput, when i tested with the master control panel application. But when i do testing with the android application, i can see the increased packet loss with minimized connection intervals.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/3397?ContentTypeID=1Tue, 26 Nov 2013 08:17:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1a5d03c0-2ab9-4238-98e7-719e0ca1b4e9Bastiaan<p>how minimum connection interval and maximum connection interval affect the throughput, i have studied so many documents but still can&#39;t find the answer, i am using min. conn int of 500ms and supervision timout of 4s, how much thourghput can i achieve? in my app i am sending data of 20 bytes for every 10ms, i dnt have any problem in that case, how it is related to conn interval, could you please explain me?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/3400?ContentTypeID=1Tue, 26 Nov 2013 08:17:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c070d587-5801-4377-8ba0-ebf197a1afedGuest<p>how minimum connection interval and maximum connection interval affect the throughput, i have studied so many documents but still can&#39;t find the answer, i am using min. conn int of 500ms and supervision timout of 4s, how much thourghput can i achieve? in my app i am sending data of 20 bytes for every 10ms, i dnt have any problem in that case, how it is related to conn interval, could you please explain me?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/3402?ContentTypeID=1Thu, 17 Oct 2013 16:55:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bd558ff4-c90e-4511-b971-70e256337417syntroniks<p>The data rate may be high, however throughput is not. With a small maximum payload size in the bluetooth low energy protocol, you will not achieve 1Mbps even if the underlying radio can.</p> <p>200kb is a large application size and I have seen bluetooth low energy over-the-air updates take nearly half a minute like you describe.</p> <p>You are already using the shortest connection interval that still meets the BLE SIG spec, perhaps higher datarates are possible with nordic&#39;s gazelle or enhanced shockburst.</p><div style="clear:both;"></div>
