How to put BHI260AP+BMM150 in sleep mode

[zkz]

I have a BHI260AP+BMM150 board (similar to shuttle board). BHI260AP is connected to a host via i2c. The whole system can be put into sleep mode. Before sleep the host, I want to make sure BHI260AP+BMM150 is in sleep in order to minimise power consumption during sleep. However, I cannot find anything to control the power mode of BHI260AP and/or BMM150 via the host interface.

Is there a way to achieve this? Or am I in a wrong path?

Hi zkz,

What is your power consumption you required?
There is power consumption and operation mode table in BHI260AP data sheet, which power consumption mode matches your power consumption requirements?

Hi BSTRobin,

Thanks for reply.

We want a power consumption as low as possible. We don't need any detections to be running when sleep. We use an external button to wake up the device.

Can we turn off all sensors/virtual sensors?

Hi zkz,

You can set the sample rate to 0 to turn off all virtual sensors if you opened before. At this time, the power consumption is the lowest.

Hi BSTRobin,

When you said "all virtual sensors if you opened before", how do I find out all those virtual sensors that I need to set sample rate=0?

The firmware I use is from the BHI260AP SDK with board config: Bosch_APP30_SHUTTLE_BHI260_aux_BMM150.cfg.

It includes a large list of virtual sensor drivers as follows. Do all of them need to be set sample rate=0?
