ESP BLE MESH Fast Provisioning

[koteswara]

I am using three ESP32 Modules to form a BLE Mesh Network and I have uploaded the following example code to all three ESP32 boards.

https://github.com/espressif/esp-idf/tr ... rov_server

Ultimate aim of this example is that mobile device will provision a node i.e one ESP32 and that node has to provision the other two nodes to the mesh network. I am able to provision only one node and that node is not provisioning other two devices . I followed the below steps :
1.Uploaded the all example code which is in URL to all ESP32's
2.In EspBLEMesh app I started provisioning and then filtered the available ESP32's by UUID "dddd"
3.I was able to find the all the three devices and selected one of them.
4.Before provisioning that node I selected fast provisioning and entered the Expect fast provisioning count as 3
5.My EspBleMesh application is connected and in fast provisioning application i am finding only one node which is connected and i am able to control that.

I Confirmed that connected node is not provisioning other devices by seeing the Blue LED. If the node has got provisioned then the blue light will turn off automatically. But the Blue light of other nodes are not offed as they are not provisioned .
How I have to solve this error ? Do I need to add any AppKey and NetKey to the EspBLEMesh application ?

We will use the above code for testing. You'd better be able to add the log so that we can quickly locate the problem.

These screenshots are from the device which has got provisioned by the mobile device by EspBleMesh Application.I am sharing the screenshot of other devices which are ready to provision .

I use the master branch of github to try the basic function is normal, you should check the version of the app. The key operation steps are shown in the attached figure:

Thank You .

Resolved by using the Updated EspBLEMesh Application

After provisioning one node my mobile is disconnecting to the node and that provisioned is provisioning all other nodes. When provisioning of nodes in the network is completed, the first provisioned node is not connecting to the mobile . Thus I was not able to control the nodes.

Hi @koteswara

After all the nodes are provisioned, you need to choose the first provisioned node on the app and connect will it manually.

Thanks.

hello, I meet the same problem. However, upgrading the app didn't solve the problem. The app sucks here and the two other boards are not able to be provisioned.
My IDF is v4.0.1 and Development Kit: [ESP32-DevKitC]
Kit version (for DevKitC): [v1]
Module or chip used: [ESP32-WROOM-32]
can you give me some advice?

Hi
I run this example :
https://github.com/espressif/esp-idf/tr ... rov_server

and I have this Problem exactly and even after update app version still not solved !
the different is, so I use two dev board not 3 board but I think it's not matter

ESP-IDF : 4.3
ESP32-wroom-32 devkit

thanks
