ZNP and IEEE MAC ADDR

Other Parts Discussed in Thread: CC2530, Z-STACK

I presume that for production devices using the ZNP with TI provided HEX files (no custom code on the ZNP and topology is a simple star), we can use the IEEE addr in the ZNP.
The Wiki mentions this
"Every Zigbee device has a globally unique eight byte identification number, called the Media Access Controller (MAC) Address, or IEEE Address, or Long Address. This can be used to identify any Zigbee Device. It is similar to an Ethernet MAC Address. It is hard coded into the CC2530 and cannot be changed without an external programmer. Unless you have a very compelling reason to change it, it is recommended to use the MAC Address that comes from the factory. "
But saw it mentioned elsewhere that there may be problems using this addr. Can't locate that reference(it was not on the TI forum)
I am hoping I do not have to get IEEE addresses. Even if I did, I see no IEEE addr set as part of simple API or AF_ZDO. Madhu

    Hi Madhu,

    Unless you have very special reasons to change this address, you should use the one that is pre-programmed at production. It will then identify as a TI chipset with an IEEE address from the TI range.

    Hi Madhu,

    CC2530 provides two IEEE Address spaces, Primary and Secondary. Primary IEEE Address is created uniquely for each device within the range secured by TI and assigned to the device at production. Primary IEEE cannot be changed. However if Secondary IEEE Address is set to non-0xFFFFFFFFFFFFFFFF value, Z-Stack will use the Secondary IEEE Address instead of Primary IEEE Address. Secondary IEEE Address is 0xFFFFFFFFFFFFFFFF out of the box, but can be programmed by using either SmartRF Flash Programmer or function call osal_nv_write() with the item index ZCD_NV_EXTADDR as one of the parameters.

    For more information, please see Chapter 7.2 of "Z-Stack User's Guide - CC2530DB.pdf" distributed with Z-Stack.
