Count router discarded indirect messages

Pedro Amaro

Hello:

I’m experimenting with message relaying timeout and I want to count the number of messages a router discards.

I have the following scenario: one coordinator, one router and one sleeping end device (ZED). The coordinator sends messages to the ZED through the router because the ZED doesn’t see the coordinator. I use a configurable poll rate at the ZED and a fixed NWK_INDIRECT_MSG_TIMEOUT at the router.

My router is working with Z-Tool and I want to execute this instruction

debug_str("Discarded one message");

whenever the router discard a message to the ZED.

Where in the code can I place the debug string?

I have ZStack-CC2530-2.5.1a and my code is based on Generic_App.

Tks

Hi,

in your topology configuration, it is not possible to provision that debug code unless you change the library code.

In a single hop topology, you could check the status value in afDataConfirm().

If the status code is 'ZMacTransactionExpired' (0xF0), then the indirect message has been purged out from the parent indirect messages buffer.

Thanks,

Hi Pedro,

You say you use configurable poll rate on ZED. Does ZED not polling or is polling duration very long when message is missed?

Tks DarkSide,

You mean the TI2530DB folder contents?

That is: unless TI exposes that information in some function I dont have acces to the indirect message buffer of a router?

Right?

Tks YiKai,

ZED is polling with long intervals. Messages are droped but it is deliberated. I just want to be warned that a message has been droped by some router...
