https://devzone.nordicsemi.com/f/nordic-q-a/113846/no-reading-from-max30001-ecg-sensor-using-nrf-connect-sdk-with-zephyrI&#39;m currently working on a project using the nRF52840 board with the MAX30001 ECG sensor. I&#39;m using nRF Connect SDK with VS Code version 2.6.1 to develop the project on Zephyr. I&#39;ve configured the following pins for SPI communication with the MAX30001en-USTelligent Community 13Wed, 14 Aug 2024 08:14:44 GMThttps://devzone.nordicsemi.com/thread/498209?ContentTypeID=1Wed, 14 Aug 2024 08:14:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3f791218-2fdd-4b60-bfe5-5659d610284aNaeem Maroof<p>Please check the datasheet for that sensor.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/497766?ContentTypeID=1Mon, 12 Aug 2024 09:47:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:30a9e1a5-2219-4aeb-9074-2e15eb05cb8cmanoj_patil<p>Thank you for pointing that out. It seems like I&#39;ve missed some important configuration settings for the MAX30001 sensor. Could you please guide me on which specific registers or configurations I need to adjust in order to start receiving accurate ECG data? Any details or steps would be greatly appreciated.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/497757?ContentTypeID=1Mon, 12 Aug 2024 09:31:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:224fc060-02fa-44ce-aeee-11c46477e1c7Turbo J<p>You probably missed some configuration registers, the 0x37 value means &quot;FIFO EMPTY&quot;. See datasheet Table 48 on page 65 (ecg fifo data tags).</p><div style="clear:both;"></div>
