Reasons Router deosn't send Beacon

Other Parts Discussed in Thread: Z-STACK

I am trying to debug why a router build doesn't send Beacons when it';s powered up(It doesn't join any network).
What might be the root causes for this? When device powers up it goes to DEV_INIT so I'm sure it's in right state but again it doesn't send any beacons.

As for flags, NV_RESTORE is defined and HOLD_AUTO_START is undefined.

If you enabl NV_RESTORE on router and it had joined any Zigbee network, network information would be kept in NV. Then, this router won't send beacon request when it is powered off and on again.

I disabled it and programmed device again. It only sends "One" beacon and that's only when is powered up, It doesn't send beacons continuously.

Can you specify which Z-Stack version and example you test this?

It's a custom application it's not examples but Ti files have not modified. It's Zstack Home 1.2.2

I have no similar problem using Z-Stack example. I suggest you to test original example in Z-Stack Home 1.2.2 to verify this.

I tried I know it works with examples. I want to have the bigger picture to be able to understand and debug what are reasons if beacon is not sent. The Zmac_init() function is same for both so it's hard to understand why no beacons are sent.

One other question, should it always send LinkStat messages? My coordinator sends them continuously, but router programmed with GenericApp, stop sending LinkStats after couple of minutes.

I also do lots of modifications to Z-Stack in my application but I don't have the same issue. I suggest you to remove your modifications one by one to see which causes the problem.
