  37          //  Description:
  38          //      If the transceiver is ready (in idle mode), the transmit section will
  39          //              be powered up and the RF interrupt enabled. The RF ISR will then 
  40          //              transmit the packet (pTXInfo) and receive the ack (if requested). If
  41          //              requested (sppSettings.txAttempts = n), the packet will be re-
  42          //              transmitted (n-1) times, until the ack is received. When finished the 
  43          //              transmit section will be powered down.
  44          //              
  45          //              This function will return immediately and the application can 
  46          //              continue while the ISR transmits the packet. When finished, 
  47          //              sppStatus() will return IDLE_MODE. During the transmission it will 
  48          //              return TX_MODE or TXACK_MODE.
  49          //
  50          //              After the transmission: Use pTXInfo->status to find out what happened:
  51          //                      SPP_TX_ACK_INVALID = Something was received, but not the ack
  52          //                      SPP_TX_ACK_TIMEOUT = No response
  53          //                      SPP_TX_FINISHED
