BLE Mesh Low power and Friend node working code

[esp_embedded]

I am looking for a sample code for BLE Mesh Low power Node and Friend node. I have tried to run the BLE mesh example and configured the configuration to enable LPN functionality on one of the ESP32 and Friend functionality on another ESP32.
But looks like friendship is not getting established OR getting terminated.

I am looking for working sample code for BLE mesh LPN and Friend node since one week but, not able to find any answers related to this on ESP forums or stackoverflow or other forums.

This is the last chance we are trying here. If this is not going to work out for us, we may need change the platform to some other micro-controller for our product !
