CC2530: Notifications on WRITE cmd

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

Hi guys,

are you aware of any official way, how application can be notified on WRITE command in Z-Stack 1.2?

I can see in older discussions, it is possible to catch the command in zcl.c in zclProcessInWriteCmd but I'm wondering if it is possible to be notified without hacking the core components?

I'm wondering why there is no event or something that would notify application. Otherwise I need to periodically check and compare the values of my attributes to detect any change/update...

Is that how it was supposed to be used?

Thank you.

Basically, you can process "case ZCL_INCOMING_MSG:" in your zclXXX_event_loop.

Hmm.. as I see in zcl.c it seems to me that it would NOT be called e.g. on ZCL_CMD_WRITE

It seems it is initiated by zcl_HandleExternal and it is probably only registered to ZCL_CMD_WRITE_RSP..

Or am I wrong?

Yes, you are correct and I suppose you can add your own code in zclProcessInWriteCmd to send event notification to zclXXX_event_loop by referring to codes in zcl_HandleExternal.
