https://devzone.nordicsemi.com/f/nordic-q-a/89355/nrf9160-problem-with-i2c-when-two-sensors-are-connectedMy project requires two sensors to operate on the same i2c bus, one of which is a display and the other of which is a touch sensor. And I have a problem where, if I test both devices without connecting them simultaneously, both will function normallyen-USTelligent Community 13Fri, 29 Jul 2022 09:53:07 GMThttps://devzone.nordicsemi.com/thread/379278?ContentTypeID=1Fri, 29 Jul 2022 09:53:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f5136f30-70cb-406a-82c8-66dd6cef7c10noob_123<p>How did you configure two different sensors on the same i2c bus? Did you create two different instances? Can you elaborate on how you did this?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/377300?ContentTypeID=1Mon, 18 Jul 2022 02:11:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cc0c2f56-fc7c-4494-9da5-69818fff8293wasan<p>Sorry for the late answer. I&nbsp;found the root cause problem. There was a problem with the sensor ic. I&#39;ve already talked to the&nbsp;my supplier that makes my sensors about how to fix this problem.</p> <p><br />Thank you.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/374331?ContentTypeID=1Mon, 27 Jun 2022 11:14:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9954cc21-28a4-41c2-96f1-6f092f752fa8Vidar Berg<p>Hi,</p> <p>20 cm is fairly long for i2c. Is it possible to shorten it a bit? You may also try enable high drive on the pins as suggested in the &quot;<span><a title="Pullup resistor" href="https://infocenter.nordicsemi.com/topic/ps_nrf9160/twim.html?cp=2_0_0_5_16_9#concept_twim_timings">Pullup resistor&quot;</a> of the TWIM chapter.</span></p> <p><span>Best regards,</span></p> <p><span>Vidar</span></p><div style="clear:both;"></div>
