Hi,

For an LPN node to communicate to a normal node you need first to have established a friendship. I recommend you take a look at the LPN example in the nRF5 SDK for Mesh and follow the steps for "Testing the example".

See also "Establishing a Friendship" section.

Best regards,

Hi Marjeris,
I follow your guide and it work. So lpn can receive message after establish friendship, but friendship terminated after receive message by reason 2. How it retain friendship persistent?
Thank you so much.
