BME 680 addressing

[Sailrexboat]

Greetings, 
Very new to OpenPlotter, so hoping someone can help with a configuration. I am trying to connect a BME 680 sensor using the I2C 4.2.0 utility. When I check I2C Addresses, my sensor correctly maps to 0x77. When I add the BME 680/688 in the Supported Sensor drop down, and 0x77 in the Detected Addresses drop down, I get an error message stating “Error processing BME 680/688: Failed to find BME680! Chip ID 0x41”. I do not have any device at the 0x41 address. Any help would be greatly appreciated!

You may be mixing up two things here. 0x77 is indeed an I2C address but then you say " I do not have any device at the 0x41 address". As the error message says, the 0x41 is a Chip ID not an address.

I think there are some BME680 python scripts out there to allow you to test the BME680 outside of OP, maybe try some of those to validate it is working?

Thanks for the input. My BME sensor does work ok, but it seems the IMU I had connected to the I2C buss developed an issue and interfered with the BME. The IMu had worked with OP, but now seems to be non-functional. Not sure what happened, but it is not important to my project. Thanks again for the input.

normally you are able to set the address line of the bme680 to another address with one pin on it´s board.
