How do I set the output power of the radio?

The Tx power can be dynamiclly changed by calling eAppApiPlmeSet(PHY_PIB_ATTR_TX_POWER,level)

For example:

bool_t bSetTxPower(int iPower) // -30 <= iPower <= 0
{
   bool_t bRetVal;
   uint32 u32TxPower;
  
   if(iPower <= 0 && iPower >= -30)
   {
      bRetVal = TRUE;
      u32TxPower = iPower & 0x3F;
      eAppApiPlmeSet(PHY_PIB_ATTR_TX_POWER, u32TxPower);
   }
   else
   {
      bRetVal = FALSE;
   }
   return bRetVal;
}

 
The output power setting is internally quantised in 6dB steps, hence the value will be rounded to the following possible values:

0dB
-6dB
-12dBm
-18dBm
-24dBm
-30dBm

So bSetTxPower(-11) will actually set -12dBm
