The nrf51822 based device, base station (BS) and server running on cloud. Problem Statement: I need to continuously (every 50msec) send value from nrf51822 to base station. Base station also needsen-USTelligent Community 13Sat, 28 Jul 2018 07:01:44 GMThttps://devzone.nordicsemi.com/thread/141768?ContentTypeID=1Sat, 28 Jul 2018 07:01:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5ca5e2d3-af6f-4b47-9d4e-d7514b2763ddRohanKadam<p>Thanks for the reply Einar Thorsrud.&nbsp;</p> <p>I would surely try out your suggestion. The only drawback I see is it might increase power consumption of my nrf51 device. But there will be always some trade-offs.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/141700?ContentTypeID=1Fri, 27 Jul 2018 13:24:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2aafd861-0ec1-405e-ade8-0f06bb8b5d0aEinar Thorsrud<p>Hi,</p> <p>BLE is reliable, and you will always get retransmissions on the link layer. You write that retransmission is not feasible due to the needing data every 50 ms. Why is that, is the chunk of data you need to transmit every 50 ms larger than you can fit in one BLE packet? You could set the connection interval down to 7.5 ms making time for several retransmission (assuming you only need one packet for each chunk of data).</p> <p>BR,</p> <p>Einar</p><div style="clear:both;"></div>
