in BME688 sensor in which Reg we have to write for parallel mode operation with I2C protocol

[Ajay_0107]

Sir, My communication is built with I2C protocol and I am getting the exact chip but my variable are not changing so please suggest the correct value for all reg we have to write for parallel mode operation with I2C protocol

Hi Ajay_0107,

Didn't you use BME688 sensor API?

On page 35 of the BME688 datasheet you can find how to select the operating mode.

In the General Control Registers there's a field called Mode.  It's 2 bits wide and has the following settings:

mode 00 - Sleep

mode 01 - Forced mode

mode 10 - Parallel mode.

Note - mode 11 isn't used. 

You can download the datasheet from the BME688 sensor page.

Hope this helps.

Hi Ajay_0107,

We recommend that you directly use the BME688 sensor API and examples, as they have already implemented how to access registers and demonstrated different operating modes.
