| The same way, using APS_DataReq(). There is no "change one-line solution", you'll need to understand how demo application works and modify it accordingly. |

Thank you alexru,
I made the coord send frames to it self (just testing) and i figure that the problem is the endDevice, it just ignore frames... i have try doing the same thing (send frames to it self) but nothing happens...
I did following changes cause i think the problem is the address:
//Configuring EndDevice like source
simpleDescriptor.AppDeviceId=CPU_TO_LE16(2);
//Configuring EnDevice like dst
messageParams.dstAddress.shortAddress=CPU_TO_LE16(2);
...
//Config msg
messageParams.asduLength=5;
messageParams.asdu = (uint8_t *)("HELLO");
//Callback
void APS_DataIndDevice(APS_DataInd_t *indData)
{
//indData = indData;
appSendLcdMsg(indData->asdu);
}
And i know that it sent frames cause APS_DataConf() works |

Hello again,
i cheked that endDevice address was wrong...
I checked my real endDevice address from this:
static void ZDO_StartNetworkConf(ZDO_StartNetworkConf_t *confirmInfo)
{
//MY LINE CODE
appSendLcdMsg(confirmInfo->shortAddr);
appTaskHandler(
APP_NETWORK_STARTING_DONE,confirmInfo);
}
but i retrieve a strange result like "UUUU>>>C" what it is mean? and never is the same when i restar it, but that is because is selected randomly by the stack right?. |

ok! I did it! I set the endDevice send frames to it self too.
but now i have a new issue...How coordinator extracts the short address of the frame that comes EndDevice?
The problem is here:
void APS_DataIndCoord(APS_DataInd_t *indData)
{
appSendLcdMsg(indData->asdu);
messageParams.dstAddress.shortAddress = indData->srcAddress; //ERROR!
} |

is incorrect. You need to define place for headers and footers.
2. You should look at the definition of APS_DataInd_t. In this case it is indData->srcAddress.shortAddress (or .extAddress); you also need to take into account addressing mode (indData->srcAddrMode). |

Thanks for your reply alexru,

I got it, I set the EndDevice to send frames to itself.
Code:
// Prefilling request parameters messageParams.profileId=simpleDescriptor.AppProfileId;
messageParams.dstAddrMode=APS_SHORT_ADDRESS;
messageParams.dstEndpoint=1;
messageParams.clusterId=CPU_TO_LE16(1);
messageParams.srcEndpoint=simpleDescriptor.endpoint;
messageParams.asduLength=6;
messageParams.asdu=(uint8_t *)("HELLO");
messageParams.txOptions.acknowledgedTransmission=1;
messageParams.radius=0x0;
messageParams.APS_DataConf=APS_DataConf;
to get the destAdress:
Code:
static void ZDO_StartNetworkConf(ZDO_StartNetworkConf_t *confirmInfo)
{
messageParams.dstAddress.shortAddress=confirmInfo->shortAddr;
appTaskHandler(APP_NETWORK_STARTING_DONE,confirmInfo);
}
and to show on display:
Code:
void APS_DataIndDevice(APS_DataInd_t *indData)
{
//indData = indData;
appSendLcdMsg(indData->asdu);
}

Now, to send frames from coordinator to EndDevice.
The coordinator must get the adress of the EndDevice and use it, right?
I tried get it by APS_DataInd function but nothing...
and by ZDO_MgmtNwkUpdateNotf function and nothing too.
How do i for the Coordinator get EndDevice's address?

I'm sorry, but I will not reply unless you correct the error in this line:
Code:
messageParams.asdu=(uint8_t *)("HELLO");
\
It might work right now, but you've got memory override problem here. |

Ok, I'm taking up Header and Footer space...
So, my "HELLO" must be in data field of AppMessageRequest_t struct
and back to the same code line:
messageParams.asdu =(uint8_t *)(&appMessage.data);
EndDevice:
So, In the apropriate struct I added "myData":
Code:
//--------------------------------------------------
// ASDU
typedef struct
{
uint8_t header[APS_ASDU_OFFSET];
AppMessage_t data;
uint8_t footer[APS_AFFIX_LENGTH - APS_ASDU_OFFSET];
} PACK AppMessageRequest_t;
END_PACK
//--------------------------------------------------
Code:
BEGIN_PACK
typedef struct
{
uint32_t myData;
uint8_t messageType;
uint8_t nodeType;
ExtAddr_t extAddr;
ShortAddr_t shortAddr;
uint32_t softVersion;
uint32_t channelMask;
PanId_t panID;
uint8_t workingChannel;
ShortAddr_t parentShortAddr;
uint8_t lqi;
int8_t rssi;
//additional field
uint8_t boardType;//1
uint8_t sensorsSize;//1
struct {
int32_t battery;
int32_t temperature;
int32_t light;
} meshbean;
} PACK AppMessage_t;
and give it "HELLO" Frame:
Code:
AppMessageRequest_t appMessage;
appMessage.data.myData = "HELLO";
messageParams.asdu =(uint8_t *)(&appMessage.data.myData);
In Coordinator
Code:
void APS_DataIndCoord(APS_DataInd_t *indData)
{
//---------------------------------------------------
appSendLcdMsg(indData->asdu);
//---------------------------------------------------
}
But this doesn't works properly...
What I missed? |

"HELLO" is not of type uint32_t.
Compiler should have complained about this. |
