CC2530: Delay between successive (Identify) packets too short - ZSTACK 3.0.2

Mario DW

Part Number: EtiCC2530

The ZSTACK 3.0.2 seems a bit too active when it sent the Identify packet ot the 0x203f NWK address.

Apparently the minimum delay between repeats was not always respected (between frame 11 and 12 there was less than 0.1 seconds).

Frames 20 to 24 are very close as well.

As a result the ack from the ZED is observed only after the first repeat, and despite the acks, the ZSTACK3.0.2 continues sending the frame.

What can be done to improve this (minimum delay between frames, etc)?

Hi Mario,

Based on the MAC Sequence numbers, it can be deciphered that the recurring Identify packets are all retries of the original. It is not clear why all are sent since a MAC ACK is returned after the first retry. Does this happen consistently and occur for all devices? I notice that ZCL Disable Default Response bit is not set and yet no default response is supplied, although the retry rate is still unexpectedly quick.

Regards,
Ryan

Below is a list of the Identify requests sent by the ZSTACK 3.0.2 Coordinator.

It seems that this behavior happened a few times but it is not systematic.

A lot of repeats: sequences 74 & 171.
Two close frames (<0.1s): 139, 146 & 182

This all happened with the same device, but that's the one that I was most interested in. It's an "always on" device.
