A Proper way to let the sender know that the receiver has received the packet?

[remoteflying]

Hi,

I'm using the library "LoRaWAN_APP.h" to make a multiple sensor project. I need to put the emisor in deep sleep after it sends the data, but maybe the receiver couldn't get the data because it's reading from other emisor.

I wander if there is a way to let the emisor know if the receiver read correctly the data from it. Is there such a function in this library or I should try another library. Is there a name for this function?

I'm not sure if I can open topics here or it's just for issues in the libraries. Sorry if so.
