How to reduce Power consumption in BLE mesh nrf5_SDK_for_Mesh_v5.0.0_src

[pat24]

Hi,
I'm using the nrf52840 BLE mesh (nrf5_SDK_for_Mesh_v5.0.0_src) and some other sensors which drivers are written by using nRF5_SDK_17.0.2.
my device is battery operated. I measured current consumption in the device is (6 ma~).so I want to reduce (ma to ua) how to achieve this. In our forum, I read about mesh_disable().is it the right way to reduce power consumption and what about reliability..?  and how to integrate mesh_disable ()  into sensor_server  example?

Hi,

I would recommend you to have a look at the Low Power node(LPN) feature for mesh. If you want to reduce your power consumption then this is the way to go. 

You can read more about the LPN feature here. Also check out our LPN example and how to integrate this feature into your own project here:

Hi,

You can take a look at this thread.

I successfully  disable_mesh() and it will reduce power consumption by  150ua .also enable_mesh() works .but is it the right way to reduce power consumption in ble mesh .??

Glad you made it work. Normally when battery-based operated node is desired you can use the LPN feature but since your whole system is battery-based this will be the way to reduce power conumption in your nodes.
