MC13213 - 802.15.4 MAC/PHY - How to set ack timeout

[Spell]

Hi all,

I'm using 802.15.4 MAC/PHY codebase and I need to increase the wait duration for an acknowledgment frame.

Which is the default value for the gMPibAckWaitDuration_c pib attribute?
Can I change this value to increase the time between two trasmission?

thanks in advance,
filippo

Hi Flippo,

The ack wait duration is defined as a constant value in the 802.15.4 as 12 symbols (192uSec) and it can not be adjusted.

Thank you Mads for your reply,
reading the 802.15.4 standard I found that the ackWaitDuration must be 54 symbols for channels from 11 to 26 and not 12 like you said.
If I use a sniffer I can see the coordinator send 4 packet with a timeout of 2-3ms, this timeout in most cases is not enough for receive the ack from the end device.

This is normal for MAC/PHY library?

best regards,

filippo,

that is not correct behaviour. I would recommend that you make sure you start from scatch again using the supplied demo applications as they behave correctly.
