Issues in Scaling Bluetooth Mesh Network with nRF52840 Provisioner

Hi all,

I am developing my own provisioner with the nrf52840 chip. My idea is to be able to add at least 2000 nodes to a bluetooth mesh network with the provisioner but I am having several problems. When I add a node to the network and configure it correctly, the log looks like this:

This log shows the configuration of a node once it has been added to the network. However, when I reach a certain number of nodes added, the log shows the following failure:

It seems that the failure is related to a memory fault in the device when saving the configuration in the cdb. The configuration of my device is shown below:

It requires the following memory:

I have a few questions about my problem. Is it possible to add 2000 devices with one provisioner using the nrf52840 chip? If so, what am I doing wrong? If not possible, could the cdb be stored in an external memory?

Any suggestions are welcome.

Thanks in advance,

Ivan
