Hi,

I managed to get it working. I updated my overlay file to remove the gpios as below

&i2c1 {
/delete-property/sda-gpios;
/delete-property/scl-gpios;
};

&i2c1 {
	compatible = "nordic,nrf-twi";	
	status = "okay";
	sda-pin = <17>;
	scl-pin = <20>;
	clock-frequency = <I2C_BITRATE_STANDARD>;
	bme680@77 {
		compatible = "bosch,bme680";
		reg = <0x77>;
		label = "BME680";
	};
};

This has enabled it to work. I am not sure why I had to explicitly disable the sda and scl pins but it works!

Im using the latest, 2.0.0. I forgot to mention,I am using the nRF52840dongle.

This is code that I have used previously and it did work on older releases.

Hi,

Which version of NCS are you using? It seems that you have both sda-pin and sda-gpios defined for your i2c node.

PS I have tried using i2c1 and i2c2. I have also tried reg 77; all suggestions I found on the forum. No joy
