problem with enddevice

Now end device is continuously sending  Beacon request but is not joining to the network.

Is your coordinator still on? And also check if your coordinator enables permit join.

yes my coordinator is still on. How check coordinator enables permit join.

The coordinator in ZStack example should always enable permit join by default. Which example project and ZStack version do you use? Do you modify anything on it? Please provide some information so I can help.

I am using sample light app, and zstack is 2.5.1a. I didn't modify any thing. any more info u need? pls tell me i will provide. Because i am new to this. I don't know what are the things need to provide for help

What example do you use to test? By the way, if you reboot the coordinator, can the end device join network?

No it is not joining. Sample light app. LED 3 in not blinking while sending a beacon request, i have seen in packet sniffer, that beacon is sending continuously, but not joining, though i have reset the    ZC.

Only thing i changed is, in the preprocessor compile option, i have added NV_RESTORE=TRUE

Do you define NV_RESTORE on both coordinator and end device? Make sure you do it and test again.

Ya i define NV_RESTORE in both ZC and ZED. I tested again. Same response. i am attaching the Packet sniffer log file. Check whether, this might will help you to get rid of my problem

From your sniffer log, your coordinator disable permit join. You can add NLME_PermitJoiningRequest(0xFF) to enable it in your coordinator.

Where to add that? in compiler option? or in source code?

You need to add it in source code. You can add it in your application init function.

I have added here

void zclSampleLight_Init( byte task_id )
{
zclSampleLight_TaskID = task_id;
NLME_PermitJoiningRequest(0xFF);

. still same response.  

Ya.I got it.Thanks Yikei for helping me.
