https://devzone.nordicsemi.com/f/nordic-q-a/31309/is-it-possible-to-saadc-sample-then-update-characteristic-for-notification-50-times-per-secondHi, I&#39;m using a nRF52832, SD132, SDK14.2 on a custom board. I want to use BLE for precision, my use case require me to perform at least 50 reading from the SAADC per second. In a perfect world, I would like to be able to update in real time my useren-USTelligent Community 13Fri, 09 Mar 2018 18:38:47 GMThttps://devzone.nordicsemi.com/thread/123752?ContentTypeID=1Fri, 09 Mar 2018 18:38:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:318b0421-e2e0-4bcf-b7c4-6eefc0d4b71cStephaneJ<p>The answer is YES.</p> <p>For the slow speed issue, <a href="https://devzone.nordicsemi.com/f/nordic-q-a/31272/notification-speed-nrfconnect-vs-web-bluetooth/123748#123748">my answer is here</a>.</p> <p>For the SAADC sample while BLE notify, I took a look at the example ble_app_proximity. The issue for me was that I was using it in <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.2.0/hardware_driver_saadc.html?cp=4_0_0_2_11_1_0#saadc_blocking">blocking mode</a>.</p> <p>Now I use it with <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.2.0/hardware_driver_saadc.html?cp=4_0_0_2_11_1_1#saadc_nonblocking">double buffering</a> and with timer ! I can now reach my 50Hz goal :)</p><div style="clear:both;"></div>
