Sleep mode BMP388 not works

[GMarco_Utech12]

Hi,

I have a problem to activate the power safe mode of the BMP388 sensor. I have setted this register :

Register : 0x1B

data : 0x03

When i reread the register 0x1B the sensor responds with data 0x03, this indicate that i setted correctly the sleep mode. But if i set this register or not set the consumption of the my board not change, for example, the consumption remain the same 0.038 ampere indifferently if set the register to imposted the sleep mode. Why the consumption not change if i setted sleep mode on the BMP388 sensor ?

With the sensor BNO055 i reduced the consumption without problems.

Thanks you

Hi GMarco_Utech12,

I did test on BMP388 reference board with the following register writing values. BMP388 current consumption was less than 2uA.

reg : 0x1B data:0x03

reg:0x1C data:0x00

reg:0x1D data:0x04

After writing register values, I also double check register value with register reading.

Could you read out register values to check them on your board?
