AVR Freaks

Hi Sashal,

Thanks for your example. Where did you implement this? I am basing my application on the WSNDemo and put this request directly into the main loop with a button press.

Is yours somewhere else in the application? Perhaps in a callback function or added to the task list another way?

What security type are you running?

I thought only ED could sleep and they don't allow child devices anyway? It might not be the code then, just my implementation. See if you can catch where in the following I may have done a mistake.

When everything is working, my router should not be able to join my coordinator unless I press a button on the coordinator that allows connections for 120 seconds.

Test scenario run to disable all join requests

- I am testing only with a router and coodinator.

- Both are working on STDLINK Security with type 0.

- Randomly generated MAC and PAN is associated with the devices.

- My 128bit CS_NETWORK_KEY is matched on both devices

- I initiate your previous example with a button press on the coordinator, setting the permitDuration to 0x00 (commented out the if statement). This is done in the main loop. Also tried in the task handler, but no different.

- I also later set CS_PERMIT_DURATION to 0 for a test condition

- I first program my coordinator and press the button, request is ran, callback is called. while my router is off

- Then reprogram my router so it has no settings held form the coordinator.

router connects within 2 seconds to the coordinator. Sometimes up to 30, but generally very quick when this is done.

There has to be an implementation issue I have because the zdp request with permit join 0 is yet to stop any router that I have ever had from joining the coordinator.

Any ideas on what I might be doing wrong? or perhaps a step that I may have missed?

The button is only on the coordinator, so I press the button on the coordinator it sends through the disable request.

No change.

I added it to the appZdoStartNetworkConf callback. The router joined the network straight away still :(

static ZDO_ZdpReq_t ZdpRequest;

//permitDuration callback
static void zdoPermitJoiningResp(ZDO_ZdpResp_t *zdpResp) //callback function
{
    (void)zdpResp;
    //permitCalledBack = 1;
}

static void appZdoStartNetworkConf(ZDO_StartNetworkConf_t *startInfo)
{
	manageBlinkingDuringRejoin(STOP_BLINKING);

	//Check if the node has successfully started the network
	if (ZDO_SUCCESS_STATUS == startInfo->status)
	{
		appState = APP_IN_NETWORK_STATE;
		visualizeNwkStarted();
		#if APP_USE_OTAU == 1
		runOtauService();
		#endif // APP_USE_OTAU
		if (deviceInterface.appDeviceTaskReset)
		deviceInterface.appDeviceTaskReset();

		// Network parameters, such as short address, should be saved
		appNwkInfo.panID           = startInfo->PANId;
		appNwkInfo.shortAddr       = startInfo->shortAddr;
		appNwkInfo.parentShortAddr = startInfo->parentAddr;
		appNwkInfo.workingChannel  = startInfo->activeChannel;
		///////////////////////////////////////////////////////////////////////////////////////
		ZDO_MgmtPermitJoiningReq_t *permit = &ZdpRequest.req.reqPayload.mgmtPermitJoiningReq;

		ZdpRequest.ZDO_ZdpResp = zdoPermitJoiningResp;
		ZdpRequest.reqCluster  = MGMT_PERMIT_JOINING_CLID;
		ZdpRequest.dstAddrMode = APS_SHORT_ADDRESS;

		ZdpRequest.dstAddress.shortAddress = NWK_GetShortAddr();

		// 			if (PermitJoin)
		// 			permit->permitDuration = 0xFF;
		// 			else
		permit->permitDuration = 0x00;

		permit->tcSignificance = 0x01;

		ZDO_ZdpReq(&ZdpRequest);
		appState = APP_IN_NETWORK_STATE;
	}
	else
	appPostGlobalTask();
}

Might start with the base WSNDemo on 3.1.0...just to try and different version and see if I can at least block the join request with a simple application.

Could you possibly provide me with an example BASE wsndemo project that worked for you ;)

Hi Alex,

Thanks for the info. What security type would your recommend for a product that must have a similar key of some kind so people can't just join in without knowing it, but can still be disallowed to join through permitDuration?

Does this mean I can only use security status's 1 with a trust center key or 2 with a master key?

So after setting the coordinator and router to stdlink securtity with status 1, doing the same on the router I still get the same result with the code above. The router may take a little longer to join but in the end it still joins the network.

I also set CS_EXT_PANID 0xFFFFFFFFFFFFFFFFLL on the router and default 0xAAAAAAAAAAAAAAAALL on the coordinator...if that means anything.

I have attached the source if that helps...

I am using a Wireless Xplained RCB256RFR2 - Xpro as my coordinator and a Zigbit as my router. I changed the LED control in the bitcloud stack BSP to match the boards.

Despite what the documentation said, when I put it to 0LL, it wouldn't connect. However, when I put it to 0xFFF...it connected to whatever extended pan was available. Perhaps there could be an issue surrounding this?

I put the extended pan back to 0LL instead of the 0xFF...LL and the permitDuration appears to be working correctly now. Rejoin (NWK_JOIN_VIA_COMMISSIONING) when the router restarts doesn't however, I think I just have to create an implementation for this, perhaps wasn't included in the wsndemo?

Interesting that when providing an extended PAN of 0xFF...LL it always connects despite the permitDuration value.
