ESP BLE MESH node self provisioning

[mpoonawala]

Hello,
I am developing firmware using the esp32 wroom-32e n16 module, its goal is to have a BLE MESH network, with multiple nodes (approx: 50) and a mobile app working as the client node in the mesh network for transmitting and receiving data.

I am stuck in a scenario where I don't have the liberty to provision even a single device from the app, considering the esp32 has static unicast addr, unique uuid, netkey and appkey. I want the unprovisioned esp32 to set its status to get self-provisioned, and I will upload the same data to the mobile app to communicate with the device.

How do I do that, I am very much in need of some assistance here.
Feel free to ask any related questions.

Hoping to get a response soon.
