How to send ECG data from nrf5340 BLE at every 5mshttps://devzone.nordicsemi.com/f/nordic-q-a/96451/how-to-send-ecg-data-from-nrf5340-ble-at-every-5msWe are using nrf5340 with MAXIM AFE that gives the ECG data at 200 Hz. We want to send that data via BLE to the phone app so that a graph can be plotted and analysed. Shall we send the data every 5ms via BLE or store the readings and send at a lessen-USTelligent Community 13Wed, 08 Feb 2023 12:33:39 GMTRE: How to send ECG data from nrf5340 BLE at every 5mshttps://devzone.nordicsemi.com/thread/408856?ContentTypeID=1Wed, 08 Feb 2023 12:33:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:38c72e03-02f3-4926-ac29-98606053b524Karl Ylvisaker<p>Hello,<br /><br />The shortest connection interval in BLE is 7.5 ms, so you will have to buffer up some measurements before sending either way.<br />How many samples you choose to buffer inbetween each BLE transfer will depend on the latency requirements of your application, as well as the size of each measurement.<br /><br />Best regards,<br />Karl</p><div style="clear:both;"></div>
