Generic User Property Server Model not receiving messages

[agurusami]

description
I cannot verify that a simple generic user property server model is receiving messages from a generic user property client model. Is this model functional? If so, can anyone please provide me with a working example? I'm new to the ESP-IDF framework, so please bear with me if this is a basic mistake!

Thank you!

local setup

Espressif IDF v1.6.2 extension on VSCode
ESP32-C3 chip
custom nRFMesh Provisioner app ( acts as both provisioner and sends the set unack message from a generic user property client model.)

troubleshooting steps taken

-used a BLE packet sniffer to verify the set unack message was being sent over the network
-debugged via JTAG/GDB to verify the server model had the intended user properties with read/write access
-programmed a Generic User Property Client Model on the same node (using the ESP-IDF framework) to send a get message[/list][/list]
