Re: [Tinyos-help] [TinyOS-2.x] CollectionSenderC.send() command is not working

[Peizhao Hu]

Sorry to re-post again,

in addition to previous question, i tried to modify my application with 
checking package size before enter send command.

regdata_t regdata;
message_t regMsg;

void registration()
 {
   if(regCount > 0)
     {
       if(!sendbusy && sizeof(regdata) <= call 
SensDataRoot.maxPayloadLength())
       {
          /* send out registration */
          regdata_t *regData = (regdata_t*)call 
SensDataRoot.getPayload(&regMsg);
          regData->id = TOS_NODE_ID;
          //regData->count = regCount;
          if(call SensDataRoot.send(&regMsg, sizeof(regdata)) != SUCCESS)
               errorLed();
          else
          {
               sendbusy = TRUE;
               regCount--;
          }
       }
       regCount--;
     }
   else
     {
       call Leds.led2On();
       /* goto sleep mode */
       op_commands.operate = OP_MODE_SLEEP;
       op_commands.op_interval = SLEEP_INTERVAL;
       startTimer();
     }
 }


// message type of regdata_t
 typedef nx_struct regdata {
   nx_uint16_t id;
 } regdata_t;

why regdata is big than the max payload of SensDataRoot ()
sizeof(regdata) <= call SensDataRoot.maxPayloadLength()

 components new CollectionSenderC(COL_SENSDATA) as SensDataSender;
 NRCMSNodeC.SensDataRoot -> SensDataSender;

I also tried to increase the message size by MSG_SIZE=50 as well, but it 
doesn't work.

Dear TinyOS developers,

I followed the AntiTheft and TestCollection examples provided by 
TinyOS 2.0.1 to create my own application.

I have a timer, which triggers the following registration function in 
some intervals. I have verified that the code basic triggering is 
working. however, when I added the sending codes, the error led is 
toggled at every timer fired. so it does mean the send command didn't 
return SUCCESS.

void registration()
 {
   if(regCount > 0)
     {
       if(!sendbusy)
       {
          /* send out registration */
          sensdata_t *regData = (sensdata_t*)call 
SensDataRoot.getPayload(&sensdataMsg);
          regData->nodeid = TOS_NODE_ID;
          regData->count = regCount;
          if(call SensDataRoot.send(&sensdataMsg, sizeof(sensdata)) != 
SUCCESS)
               errorLed();
          else
          {
               sendbusy = TRUE;
               regCount--;
          }
       }
     }
   else
     {
       call Leds.led2On();
       /* goto sleep mode */
       op_commands.operate = OP_MODE_SLEEP;
       op_commands.op_interval = SLEEP_INTERVAL;
       startTimer();
     }


the Configuration part, where COL_SENSDATA=11:

 /* Collection */
 components CollectionC;
 NRCMSNodeC.CollectionControl -> CollectionC;

 components new CollectionSenderC(COL_SENSDATA) as SensDataSender;
 NRCMSNodeC.SensDataRoot -> SensDataSender;

My deployment platform is Ubuntu + TinyOS 2.x (ubuntu package).

any idea?
