ZigBee : MC1322x node loses parent after Deep Sleep Wake up

Elisa — Fri, 03 Apr 2009 17:41:23 GMT

Hi, I'm working with with codebase 3.0.1 and I have more or less the same problem: I want' my MC1322x ( chip version 2.0) Low Power Node goes to sleep and sends a test message to coordinator when it wake up. But sometimes, after wake up it loses its parents and like in you case "the led 1 blinking, and although I press the button 1 it remains blinking, it doesn´t make anything and it is imposible to rejoin with the coordinator. What is happening?"

To send message I added SendSampleMessage(TRUE); in DeepSleepWakeupStackProc function

/* Called each time deep sleep mode is exited. */
void DeepSleepWakeupStackProc
(
void
)
{

TS_SendEvent(gAppTaskID, gAppEvtSyncReq_c);
SendSampleMessage(TRUE);
return;
}

and defined this function in BeeApp.c

void SendSampleMessage( bool_t wakeup)
{
afAddrInfo_t afAddrInfo;
FLib_MemSet(&afAddrInfo, 0, sizeof(afAddrInfo));

afAddrInfo.dstAddrMode = gZbAddrMode16Bit_c; /* direct-16 bit*/
Set2Bytes(afAddrInfo.dstAddr.aNwkAddr, 0x0000); /* short address of coordinator */
afAddrInfo.dstEndPoint = 0xFF;/*destination endpoint =0xFF : the receiving stack will deliver that message to every endpoint on the node*/
Copy2Bytes(afAddrInfo.aClusterId, gZclClusterBinaryOutput_c);/* cluster to send it to */

afAddrInfo.srcEndPoint = appEndPoint;

afAddrInfo.txOptions = gZclTxOptions;//0; /* to ACK or not to ACK, that is the question... */
afAddrInfo.radiusCounter = afDefaultRadius_c; /* radius */

if (wakeup==FALSE)
{
AF_DataRequest( & afAddrInfo, 14, "\n Hello World\n" , NULL);

}
else
{
AF_DataRequest( & afAddrInfo, 14, "\n Goodmorning\n" , NULL);

}
}

Dear Elisa,

This is very annoying that we can't specify the destination address as in HEX formate directly it won't work out.

Actual problem is in the line

Set2Bytes(afAddrInfo.dstAddr.aNwkAddr, 0x0000); /* short address of coordinator */

To solve this problem you have to take the variable of type zbNwkAddr_t

ex: zbNwkAddr_t aDestAddress = {0x00, 0x00};

and use

Copy2Bytes(afAddrInfo.dstAddr.aNwkAddr, aDestAddress);

This may solve the problem.

Cheer.

Imran

Hi Imram,

sorry but I'm not sure you are right. The Set2Byte function is made to copy a 16 bit variable to a location, with the bytes swapped if little endian, as you can see in BeeCommon.h

/*copies a 16 bit variable to a location with the bytes swapped
Note needed for big endian
*/
#if !(gBigEndian_c)
void Set2Bytes(void *ptr, uint16_t val);

and it is used, as I used, FOR EXAMPLE in ZdpUtils.c

void GetAddressFromService
(
   ...
       case ZdoBackupBindingTableCache_c:
           if (!Cmp2BytesToZero(pPtr->aServerMask))
               Copy2Bytes(pNwkAddress, pPtr->aNwkAddress);
           else
               Set2Bytes(pNwkAddress, 0xffff);
       break;
       default:
           Set2Bytes(pNwkAddress, 0xffff);
       break;
   }
}

However,I tried to follows your indication but the problem,as I thought, didn't solve.

thanks anyway for your interest.

Bye,

Elisa

Dear Elisa,

You are right Set2Byte is made to copy 16 bit variable. But I don't know why it is not working in while copying the address.

My working code looks like this

void TxMyData()
{
afAddrInfo_t afAddrInfo;
zbNwkAddr_t DestNwkAddr = { 0X00, 0X00 };
if (!mTxZigBeeThrottleFlag)
{
TS_SendEvent(gAppTaskID, mAppRetryZigBeeDataTx_c);
return;
}

FLib_MemSet(&afAddrInfo, 0, sizeof(afAddrInfo));
zbTxDataBuffer.status = mBufStatusReadyToSend_c;
afAddrInfo.aClusterId[0] = (mDataClusterId_c & 0xFF);
afAddrInfo.aClusterId[1] = (mDataClusterId_c >> 8);

afAddrInfo.dstAddrMode = gZbAddrMode16Bit_c;

Copy2Bytes(afAddrInfo.dstAddr.aNwkAddr, DestNwkAddr);

afAddrInfo.dstEndPoint = 0xff;
afAddrInfo.srcEndPoint = appEndPoint;

/* Turn on security and leave it on. Harmless In a non-secure network. */
afAddrInfo.txOptions = 0;
afAddrInfo.radiusCounter = afDefaultRadius_c;
/* The Wireless UART application on the remote node will ack or nak this */
/* datagram (regardless of the reliability mode setting), so a confirm id */
/* is not needed here. */

AF_DataRequest(&afAddrInfo, zbTxDataBuffer.len, \
                 zbTxDataBuffer.data.structured.payload, NULL);
......

}

Hope this may help you.

Regards,

Imran
