How to wake up nrf52832 device?

Question

Hello, 
 
 I am using light switch example for nrf52832 development boards.I have enabled the low power node in client example. 
 Is it possible to configure server in normal mode and client in low power mode through nrf mesh application?

Which device are you talking about now? The low power node or the regular mesh node (the server node)? The regular light switch server node does not sleep, as it must listen to incoming messages from other nodes. The same applies to friend nodes. 
 The low power node, on the other hand, is able to wake up for a period of time & then go to sleep again. 
 The documentation provided here ( link 1 , link 2 ) is very useful. To summarize the doc, first a friendship is established between a friend node & a low power node (LPN). The friend node can have multiple friendships with different LPNs, but the LPN can only have one friendship with a friend node. During the friendship establishment process, three key parameters are decided, the receive delay, the receive window & the poll timeout. 
 The LPN sends a request to the friend node for a status update (i.e. all of the messages & security updates the LPN has missed while it has been asleep). The friend node then waits until the receive delay time has expired before it starts sending messages to the LPN. 
 The receive window is the time period in which the friend node has to send messages to the LPN. Once the LPN has received all of the messages or the receive window has expired, then the LPN will go back to sleep. 
 The poll timeout is the time period in which a LPN must send consecutive requests for updates to the Friend Node. If the LPN does not do this, then the friend node will terminate the friendship with the LPN. 
 For more info, read the documentation. It is very detailed & easy to understand.
