BLE Mesh connection problem

Hi,

I need help in develop ble mesh firmware for STM32WB.

The main problem I have is connectivity.

For tests I have two ble mesh nodes. Everything works fine when both nodes are powered on at the same time, the communication is from node1 to node2 and from node2 to node1. The problem appears when one node is reseted. For example if I reset node1 then node1 receives data from node2 but node2 does not receive data from node1. After a few minutes the communication from node2 to node1 sometimes returns but sometimes not.

Is there any problem logging in to the network?

In my application some nodes are powered on all the time but some nodes are powered on only at night and will be reseted every day.

Best Regards,
