CC2652P: [CC2652P]how can i entry HCI_EXT_ModemTestTxCmd(CW tone) from SimplePeripheral sample code.

HI TI.

I'm using SDK V5.3 with CC2652P.

I want to take my CC2652P entry CW mode.

my code is as below:

static void SimplePeripheral_taskFxn(UArg a0, UArg a1)
{
  // Initialize application
  SimplePeripheral_init();
#if 1//ass begin
  HCI_EXT_ModemTestTxCmd(HCI_EXT_TX_UNMODULATED_CARRIER,19);
  while(1);
#endif//add end.
  ...
  ...
}

But my module does not generate a CW tone.

could you give me some hint?

thx.
