https://devzone.nordicsemi.com/f/nordic-q-a/100730/nrf52833-bme280-no-i2c-connectionHello, I have a BME280 wired to a Micro:Bit V2 and am trying to read the sensor. However, communication with the sensor is not possible. The sensor is wired correctly and the I2C address is 0x76. In MakeCode the sensor can be read without problems onen-USTelligent Community 13Thu, 29 Jun 2023 12:34:36 GMThttps://devzone.nordicsemi.com/thread/433690?ContentTypeID=1Thu, 29 Jun 2023 12:34:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7d8728f6-ec8e-4ac1-86e8-691031703b8bMenon<p>Hello,</p> <p>I am not familiar with the target board you are trying here. Are you connecting any other senor here? Because I saw 2 more sensors inside the dts for I2c0, or are you trying with an integrated senor on the board ? Can you once switch to i2c1 and test whether it&#39;s the same?</p> <p>It&#39;s hard for me to reproduce this error as I don&#39;t have the target board or the senor you are trying with. I once gain recommend you to verify the output on SDA and SCLK and you can share the traces.</p> <p></p> <p>Kind Regards,</p> <p>Abhijith</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/432804?ContentTypeID=1Sat, 24 Jun 2023 22:23:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c05800fb-15d2-44a7-b373-564ebc7191d4drunkenmasta<p>Thanks for the answer.

It has a&nbsp;<span>NRF52833. I am using PlatformIO to build the project. It has not the latest version of Zephyr, but I already tried it with the latest Zephyr SDK and west, but&nbsp;the problem was the same.</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/431061?ContentTypeID=1Wed, 14 Jun 2023 14:29:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b1356fad-3e7b-4196-b789-7244b81c9e7aMenon<p>Hello,</p> <p>Could you tell me which nordic chip or Development kit you are trying this with? Please mention the SDK version that you are using here.</p> <p>Is it possible to probe the I2c lines, to verify whether the slave is responding correctly?</p> <p>&nbsp;</p> <p>Kind Regards,</p> <p>Abhijith</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/430825?ContentTypeID=1Tue, 13 Jun 2023 16:50:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4566d3fd-cf44-417a-b605-1fb5c4468672drunkenmasta<p>Unfortunately, the articles do not help me. The device is configured correctly in the device tree. The address is also correct and the sensor is also wired correctly.</p> <p>Switching between &quot;compatible = &quot;nordic,nrf-twi&quot;;&quot; and &quot;compatible = &quot;nordic,nrf-twim&quot;;&quot; does not help either.</p> <p>Still looking for a solution.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/430775?ContentTypeID=1Tue, 13 Jun 2023 13:02:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:387b4ff0-846a-49cb-9020-7db54b1d1661Menon<p>Hello,</p> <p>This Error has been discussed in this portal before.
