Question

Hi, 
 Greetings! 
 I am using following setup 
 1. Mesh SDK: 4.0.0

 3. Segger Embedded Studio on Windows 7 
 
 I had a look at "pwr_mgmt_pca10040 " example project and now I am trying to implement it in "light_switch_client_nrf52832" example 
 Can anyone suggest me steps to follow? 
 or 
 Guidelines for the same which can help me to implement it in SIG mesh example 
 Thanks in advance.

So you don't want to use the experimental_lpn low power node example ? 
 Putting the device to sleep is not what suggested in the spec. If you sleep for more than 96 hours you would need to update the IV index. Note that for mesh to works you still need a number of node acts that the backbone and those node can't be put to sleep. 
 If you want to put a device to sleep, you can first shutdown mesh and then put the CPU to sleep mode. When you wake up you can initialize the mesh network again. To disable mesh you can call : nrf_mesh_disable() 
 To put CPU to sleep please refer to our examples in the nRF5 SDK. If the softdevice is active, you can call sd_app_evt_wait() if it's not you need to call the following to put CPU to sleep: 
 __SEV();
__WFE();
__WFE(); 
 Make sure you set up the timer to wake the CPU up.
