https://devzone.nordicsemi.com/f/nordic-q-a/36517/bvraidbroadcast-messageHi, I would like to synchronize 2 Sensors with one dongle. So the problem is that we have two sensors and we want to start the measurement at the more or less (1 ms) exact time. Therefore we would like to send from the central to both peripheralsen-USTelligent Community 13Fri, 27 Jul 2018 13:03:39 GMThttps://devzone.nordicsemi.com/thread/141693?ContentTypeID=1Fri, 27 Jul 2018 13:03:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a5d4a491-848a-4fcf-9493-8286ffb4a7eaMartin Lesund<p>Hi Constantin,&nbsp;</p> <p>If you are going to send measurements at 1ms it would not be sufficient to use BLE.</p> <p>Please check out the documentations:</p> <ul> <li><a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.s132.sds%2Fdita%2Fsoftdevices%2Fs130%2Fble_protocol_stack%2Frole_configuration.html&amp;cp=2_3_1_0_9_3" target="_blank" rel="noopener noreferrer">Bluetooth low energy role configuration</a></li> <li><a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.s132.sds%2Fdita%2Fsoftdevices%2Fs130%2Fmultilink_scheduling%2Fsuggested_intervals_windows_s132.html" target="_blank" rel="noopener noreferrer">Suggested intervals and windows</a></li> <li><a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.s132.sds%2Fdita%2Fsoftdevices%2Fs130%2Fmultilink_scheduling%2Fmultilink_scheduling.html" target="_blank" rel="noopener noreferrer">Scheduling</a></li> </ul><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/140850?ContentTypeID=1Fri, 20 Jul 2018 13:48:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2329bb05-420e-4add-a108-9bb0ee11315bConstantin<p>Yes we already know it and it is fine but it is not feasible for certification since we do not pass EMC test because ESB has the frequency hopping disabled which causes a high power in only one channel and hence makes trouble during certficiation. Furthermore, our central is a smart device which does not support ESB. So we would need a solution with BLE only.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/140849?ContentTypeID=1Fri, 20 Jul 2018 13:41:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6a652d5a-8d6c-4ccc-8689-37b71cc8fff8Martin Lesund<p>Hi Constantin,</p> <p>This would be hard to achieve with BLE if you want to start measurements at 1ms.</p> <p>I would instead recommend you to check out <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.0.0%2Fesb_users_guide.html&amp;cp=4_0_0_5_1" target="_blank" rel="noopener noreferrer">Enhanced ShockBurst</a>&nbsp;for your application.</p><div style="clear:both;"></div>
