Hi again,
i’m performing a customized app ‘myCustomizedApp’ based on TestAssociate app
located in ../tinyos-2.1.1/apps/tests/tkn154/nonbeacon-enabled.
I have got two micaz motes (coord and device) programmed in a mib520 board with
the address as follows:
Coordinator –> make micaz extaddr, 0xC00D install mib520,/dev/ttyUSB0
Device –> make micaz extaddr, 0xED1234 install mib520,/dev/ttyUSB0
When i tested my app, the coordinator printed the MAC address of the only
device who was joined to him: 0x4E00000021AC75E2
That’s wrong, it should print 0xED1234.
[!] I have not made any changes in the basic structure provided by the
TestAssociate app. I haven’t modified MLME_ASSOCIATE primitives. I have only
added more lines of code for customize my app. [!]
Any help would be appreciated.
Thanks in advance,
Felipe.

Hi,
now it works correctly.
Thank you very much,
Felipe.

Check if you have file tos/lib/mac/tkn154/extras/extaddr.extra in your
system. If not you might want to update to latest code
(http://code.google.com/p/tinyos-main/source/checkout). Alternatively
(for testing) add "CFLAGS += -DIEEE154_EXTENDED_ADDRESS=1234" to your
Makefile or "#define IEEE154_EXTENDED_ADDRESS 1234" in front of your
app's configuration.
