    BME680 I2C on 0x77 not working

    BME680 I2C on 0x77 not working

    Had to change BME680_I2C_ADDR_PRIMARY UINT8_C to get my board working. With BME680_I2C_ADDR_PRIMARY UINT8_C(0x76) I got a -2 error all the time

    /** BME680 I2C addresses */
    #define BME680_I2C_ADDR_PRIMARY UINT8_C(0x77)
    #define BME680_I2C_ADDR_SECONDARY UINT8_C(0x77)

    Could I know what is the state of the SDO pin on your hardware?
    When SDO pin was connected to GND, i2c address was 0x76;
    When SDO pin was connected to VDDIO, i2c address was 0x77.
