Power Consumption of BME688

Hello,

I want to build an application with a BME688 sensor, BSEC library, and Fudan FM33LG048 ARM Cortex M0 microcontroller. I am using BSEC_2.4.0.0_ExampleCode.

My problem is that BME688 is drawing 1.34 mA current in BME68X_OUTPUT_GAS_IAQ/BSEC_SAMPLE_RATE_ULP mode. The microcontroller without the sensor draws only several microampers. However, the sensor draws 1.34 mA (here I measure only the sensor, not the entire MCU).  Therefore, I don't think that the problem is related to the microcontroller. I am using bme688_sel_33v_300s_4d. I have attached my code below.

Best Regards,
Nijat Aliyev
