What is the expected behavior?

I have developed a light node using BLE-MESH. When I provision more then 150+ devices in a single network, then I am facing connection issue from mobile app. In smaller network, it's working fine but problem occurs with large number of devices in a network. I have used nRF Mesh android sdk for provisioning, connecting and operation of devices.

Also please let me know of parameters which are important for ble-mesh connection.

What is the actual behavior?

Whenever I try to connect to BLE-MESH network from mobile app then it must be connected immediately.

Steps to reproduce.

1. Provision 150 or more devices in a single network.
2. Try to connect in network
3. Operate in network
4. Disconnect network and try re-connecting

@JiaLWang please look into the issue.

Hi @hipal31 ,

Are the devices on the network sending messages frequently?

[hipal31]

@JiaLWang No. Even after provisioning the devices in network, this issue occurs.

[JiaLWang]

Will our own example(eg: ble_mesh_node example) have this problem? If it exists, we can try to reproduce it locally.

[hipal31]

@JiaLWang Yes, please try on that. If you want then I can provide firmware binaries and App for you to reproduce the issue.

[JiaLWang]

Firmware binaries are inconvenient to add log and debug problems.

[hipal31]

You can try on example codes first. Please let me know if you are facing issue in re-generating the issue. I can give you my sdkconfig and ble-mesh configuration done in code.

@JiaLWang Any progress?

[hipal31]

@JiaLWang the issue is still exist. Can you help to solve?
