Hi Rosso,
Which example code did you refer to?
Please check your sequence is correct. For example, if you want to get data in foreced mode, you can refer below example.
https://github.com/BoschSensortec/BME68x-Sensor-API/blob/master/examples/forced_mode/forced_mode.c
And each function in BME68x API like bme68x_set_heatr_conf, we have return, so you can check whether there is error or not.
Let me know if you have further questions.
Thank you.
