disassociate feature in 802.15.4

bsaaa — Mon, 23 Jul 2007 21:07:05 GMT

Hi,

I try to implement and test the disassociate feature in 802.15.4 protocol, but it doesn't work.

I configure the message and send it, but the PAN coordinator receive nothing.

Has anyone try to do it ?

Thanks.

I used that, but it forced me to use extended address, which I don't want to use.
So I discarded that.

The disassociate feature is not so good: a dead device won't send it, and if the message is lost, no reply is provided.

So, in my case it's better to discard it.

Best Regards,
Lex

I have done my own Disassociate message, end it works well, better than those of the 802.15.4 standart.

Best regards,

Ben.

Yeah!

Does it work (also) with short addresses?

The device send the Disassociate msg with short adresses and the coordinator respond with long adresses.

Ok, probably this is very good in your case.

But unfortunately in my case the Coordinator can't remember the extended address of its children.
So maybe I could attach the "extended" in the payload of a message, or maybe discard disassociate procedure at all.
