[Smac-users] New to s-mac

[B P]

Hello all,

I am new to s-mac and am attempting to disable the RTS/CTS portion of it.  I currently think I have it off and seem to get traffic through but only at a slow rate.  If I attempt to transmit at a high rate it seems to hang.  The following are the changes that I made in an attempt to disable RTS/CTS.  Please help me if I missed some important things as I am sure I did.  I highlighted in red the changes I made.  Any help you could give would be appreciated.

event result_t CarrierSense.channelIdle()
      {
         // physical carrier sense indicate channel idle
         // start sending
         uartDebug_txByte(CHANNEL_IDLE_DETECTED);
         if (state != CARR_SENSE) return FAIL;
         if (howToSend == SEND_SYNC) {
            sendSYNC();
         } else if (howToSend == BCAST_DATA) {
            startBcast();
         } else if (howToSend == SEND_RTS) {
            //sendRTS();
            geneTime = 0;                
           state = TX_PKT;
            howToSend = SEND_DATA;
            txDelay = SIFS;
         } 
         return SUCCESS;
   }

void* handleDATA(void* pkt)
   {
      // internal handler for DATA packet
      void* tmp;
      MACHeader* packet = (MACHeader*)pkt;

      if (packet->toAddr == TOS_BCAST_ADDR) {  // broadcast packet
         uartDebug_txByte(RX_BCAST_DONE);
#ifdef SMAC_NO_SLEEP_CYCLE
         if (state == BACKOFF) state = IDLE;
         uartDebug_txByte(state);
         if (state == IDLE) {         
            if (txRequest == 1) {
               uartDebug_txByte(SMAC_TX_REQUEST_IS_1);
               tryToSend();
            } else {
               uartDebug_txByte(SMAC_TX_REQUEST_IS_0);
            }
         }
#else
         sleep(TRY);
#endif
         tmp = signal MACComm.rxMsgDone(packet);
         return tmp;
      } else if (packet->toAddr == TOS_LOCAL_ADDRESS) {  // unicast packet
         // could receive data in idle, backoff and wait_data state
         uartDebug_txByte(RX_UCAST_DONE);
         //if (state == WAIT_DATA && packet->fromAddr == recvAddr) {
