zigbee 52840 Device out of network

[chenyupeng]

When "Zigbee Dongle" is successfully connected and communicated with terminal devices, if the terminal devices that have been successfully connected to the network are all off the network, how should we detect these devices in the code at this time?  In other words, is there a flag bit variable or function in the code that indicates that "Zigbee Dongle" is not connected to any terminal devices  

I found a definition of an enumeration type in the SDK that indicates that this status bit is triggered when the device goes offline.  But I don't see any other variable or function API defined to indicate that "ZigBee Dongle" doesn't have any devices connected to it.  I am now curious to know what this state should be when there are no connected devices in zigBee.

• "ZB_ZDO_SIGNAL_LEAVE_INDICATION" in the following figure indicates that only a device has left the network, but not that all devices have left the network :

Hi

Do you want an indication specifically for when all devices has left the network? I'm afraid there is no indications like this in the Zigbee SDK. To have something like this I think you need to make a function like this yourself. Which for example counts all devices that joins the network, and then also makes note of devices that have left the network, and if all devices have left it generates an event of some kind.

Best regards,
