BME688 Sequential Mode

[nkdnnlr]

Hi
In one of your forum posts (https://community.bosch-sensortec.com/t5/MEMS-sensors-forum/BME680-Gas-sensor-heater-unstable/m-p/23...) you mention the Sequential measurement mode, which seems to be the preferred mode for heater temperature profiles. Also in the bme68x.c / bme68x.h software, there is a separation between forced_mode, parallel_mode and sequential_mode. Unfortunately I have not found anything in the BME688 Datasheet documenting the sequential mode. Could you please help me out how this would look like, compared to forced and parallel mode (see below)?
Thanks in advance!

Hello, 

Please check 3.4 sensor mode in our datasheet.

Hi Minhwan, thanks for the answer. I checked the datasheet already, but unfortunately the only modes described are Forced and Parallel, where I want to use the sequential mode. Could you describe what the Sequential mode does in detail?

Thanks in advance!

Hello Nik, 

Sorry that not answering this question. 😞

Sequential mode is similar as forced mode, but it provides temperature, pressure, humidity one by one. 

However, it wasn't verified with BSEC. 

If you'd like to use BSEC, please don't consider it. 

Thank you.
