https://devzone.nordicsemi.com/f/nordic-q-a/61536/combining-ble-and-saadcHi everyone, I have written a code that sends data over BLE notifications (IMU data). It works great so far and now I want to read the analog values from eight force sensors and send them also as well. Using the SAADC,PPI AND TIMER drivers I wroteen-USTelligent Community 13Fri, 22 May 2020 06:00:18 GMThttps://devzone.nordicsemi.com/thread/251161?ContentTypeID=1Fri, 22 May 2020 06:00:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5f09effb-c5d8-410c-b4b9-c8acdadfcd6dNikosant03<p>Hi Jared and thank you for your help,</p> <p>I re-wrote my code using a different approach and it works fine. Basically I created a second RTC timer for SAADC operation.&nbsp;So, now I have two timers, one for the SAADC and one to update the payload and send a notification. This is the flowchart of how my code works</p> <p></p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/Events_5F00_Timers_5F00_Notifications.png" /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/251053?ContentTypeID=1Wed, 20 May 2020 15:08:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e3def848-3d91-442d-9909-bd79bb524d0aJared<p>Hi,</p> <p><span>Which SDK are you using? Could share code where you initialize the SAADC?</span></p> <p>The first step would be to check what&nbsp;nrf_drv_saadc_sample() returns in the loop. Is the SAADC operation queued successfully?</p> <p>regards</p> <p>Jared</p><div style="clear:both;"></div>
