CC2530: ZDO_TC_DEV_IND meaning?

Part Number: CC2530
Other Parts Discussed in Thread: Z-STACK, CC2531

Can someone describe what the ZDO_TC_DEV_IND callback means, or preferably point to some docs that explains this? I'm seeing this callback when a device joins the network - I assume that this is a notification to the TC that a new device has joined, but does the TC need to do anything in response to this?

Unfortunately the devices don't seem to actually join as they don't respond to any messages so I'd like to understand why this is.

Thanks.

    If I am not wrong, it offers an API/callback to allow the application to know when the Trust Center has given out a key.

    Hi Chris,

    As YiKAi says, this is an indication that the TC has delivered the key to a recently joined device. Unfortunately seems like there is not much information in the documentation on this regard (or I am not aware of it), besides the serial frame definition in 'Z-Stack Monitor and Test API.pdf'. If you do not see your devices respond to any command, it is probably that they do not have the same preconfigured key or may not have security enabled at all.

    Which stack version are you using?
    Do you have any sniffer log that you can share?

    Hope this helps!

    Thanks for the feedback. Yes, the frame format in the Monitor and test API document is also all I've found, but it's not so useful to know what it actually does... I also assumed it was simply a notification that the TC has approved a device association, so in this respect we're all assuming the same :).

    This is running on a users system, so I don't have 100% control over the firmware, and don't have a sniffer log (although I've requested it - let's see...). The version information returned from the stack is CC2531 version is Software=2.6 Product=0 Hardware=3 Transport=2.
