https://devzone.nordicsemi.com/f/nordic-q-a/81403/empty-readings-from-lsm9ds1-registersHi, I am trying to connect my LSM9DS1 with nrf52840, this is Arduino nano 33 BLE board. I already figured out that i had to enable it and enable TWI bus. After some readings i found example with the library for this sensor https://devzone.nordicsemien-USTelligent Community 13Wed, 09 Mar 2022 20:54:45 GMThttps://devzone.nordicsemi.com/thread/357276?ContentTypeID=1Wed, 09 Mar 2022 20:54:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:375a3037-b977-4ecb-b666-4d39a1588d18austin944<p>I don&#39;t know if this helps, but I got the TWI to work with an Adafruit IMU (LSM6DS3/<span>LIS3MDL</span>) and the nRF52840 Dongle.&nbsp; My code is at:</p> <p><a href="https://github.com/doug-holtsinger/WirelessSensor/blob/master/Sensor/src/TwoWire.cpp">https://github.com/doug-holtsinger/WirelessSensor/blob/master/Sensor/src/TwoWire.cpp</a></p> <p>Rather than using the&nbsp;nrf_drv_twi_tx() function followed by the&nbsp;nrf_drv_twi_rx() function, I used the&nbsp;nrfx_twi_xfer() function with the&nbsp;NRFX_TWI_XFER_DESC_TXRX descriptor.</p> <p>BTW if you have a github repos available, I would like to follow your project, if you don&#39;t mind.&nbsp; It looks like we might be doing similar things.</p><div style="clear:both;"></div>
