NRF MESH SDK LOW POWER MODE

[Dev1]

Hello,

I am using SDK2.0 for Mesh on nrf52840, 
I have not found any material related with  low power mode support of nrf52840.

Is low power mode on MESH SDK not supported  yet?

Hi BLE Mesh LPN (Low Power Node) is not implemented yet as it needs a Friendship model which is still in development. So you cannot have any low power node yet using Mesh SDK alone

Thanks much for you response.
Is it possible use sd_power_system_off from SDK15.0 for sleeping?
And if yes,  are ble advertisement messages will be continuing?

Hi Devi,

For now the Mesh protocol uses TimeSlo API and keeps the RADIO on most of the time. You cannot use sd_power-system_off and expect to keep the node in the network.

Thanks again for information!

no problem, please wait some more time till we implement the friend model when you can use a low power node. The timescales are little unclear now, but you can ask more about the timelines for this features to your Regional Sales Manager,
