How to get the capabilities / extAddr / nwkAddr of a new device added on zigbee network?

Other Parts Discussed in Thread: CC2531EMK, CC2531

Hi all...

I´m using cc2531emk as a coordinator on ZigBee HomeAutomation network.

The cc2531emk interact with pc by Usb class cdc library, (http://processors.wiki.ti.com/index.php/CC253x_Serial_Boot_Loader)

Now I want to save on cc2531, and later send to pc by usb, the address of new devices that join the network.

To get the address os new devices i'm use ZDO_RegisterForZDOMsg( GenericApp_TaskID, Device_annce ); (http://processors.wiki.ti.com/index.php/Z-Stack_FAQ#How_to_get_the_address_of_new_devices_joining_the_network )

But " ZDO_ParseDeviceAnnce( inMsg, &msg); " give me the pointer for:

- msg.capabilities

- msg.extAddr

- msg.nwkAddr

How do I get the msg.capabilities / msg.extAddr / msg.nwkAddr and put them on a normal variable like char, or uint?

Dears,

msg.capabilities gives you one byte of device capability, in which capability contains the following bit flags:

Bit: 0 – Alternate PAN Coordinator

Bit 1 – Device type: 1- ZigBee Router; 0 – End Device
Bit 2 – Power Source: 1 Main powered
Bit 3 – Receiver on when Idle
Bit 4 – Reserved
Bit 5 – Reserved
Bit 6 – Security capability
Bit 7 – Reserved

msg.extAddr contains 8 bytes IEEE address pointer

msg.nwkAddr contains 2 bytes short address pointer

Thanks again YiKai Chen ...

But msg.extAddr is a pointer for a unsigned char, not a byte like msg.capabilities and msg.nwkAddr.

How do I put this value in a uint32 variable?

Yikai,

How does the cc22530 know how it's powered? ie. Bit 2 – Power Source: 1 Main powered

Dears,

In general, a router is main powered and ED is not. If your ED might be battery or main powered, I will suggest a GPIO to detect it.

Cool, GPIO was how I was planning to do it ! I thought for a second I lucked out and it already detected it "magically" :)
