As I know, the ZigBee Control Bridge node by default uses the internal EEPROM to hold persisted data. This is about 4KByte in JN5169 device and can restrict network size.
To overcome this, we need to export the data persistence to the host device.
How do I enable this feature?
p/s: I am using JN-AN-1216-ZigBee-3-0-IoT-ControlBridge
