Hi Sorry I don't understand what you mean with this. Which example in sequential_mode are you talking about? In the datasheet I only see forced and parallel. My question is: I want to get the data readings for all the temperature steps. How do I read it in time without the buffer to be overwritten? And which register tells me which temperature step was selected? Thanks in advance. Nik ... View more

Ok I think then I misunderstood something. I am not talking about learning any gas yet. The only thing I want is to apply a temperature profile of, let's say, 10 steps, and read out the data at each step.Like this: Based on the below image, I thought gas_index is the same as gas_meas_index and gives me the index of the heater step, so that is not the case?   ...

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! Nik ... View more

Hi Sébastien I am curious to hear if you can read out anything at all with all registers set to zero 😁 but yes I am sure you will manage! Let me know if there is anything else I can help regarding this. Cheers, Nik ... View more

Hi Sebastien I just had to do the same. in forced mode, if you set the heater duration and temperature to (0, 0), and if you set the conf.enable bit to BME68X_DISABLE (which is UINT8_C(0x00)) then you don't measure the gas anymore. I then also commented out some of the waiting times in bme68x.c -> bme68x_get_meas_dur() and managed to achieve sampling rates for pressure, humidity, temperature of 100Hz. see how it looks for me: I have not fully characterized the stability of the sensor with those settings, but looks alright for now.
