BME688 sensor not found on Boron

I cannot get a reading with my code. I have the SCK on the 688 connected to the SCL on the boron and the SDI to SDA. Do I need to add some pullup resistors?

I would try running an I2C scanner to see if any device can be seen.

I think the default is 0x77, not 0x76.

By default, the i2c address is 0x77. If you add a jumper from SDO to GND, the address will change to 0x76.

This worked on my BME680 and BME688. Had to flip the SLC/SDA wires, won’t work if backwards

Got it. I had the wrong address. Thanks @rickkas7
