Adding SPI to Simple Peripheral on CC2650, send data but never finish transfer

Hi, I'm trying to use a Sensor in Simple BLE Peripheral Example using SPI. I can use it perfectly in TI-RTOS without BLE Stack on CC2650.

I use the launchXL-CC2650

The SPI configuration is:

SPI_Params_init(&spiParams);
spiParams.mode = SPI_MASTER;
spiParams.transferMode = SPI_MODE_BLOCKING;
spiParams.bitRate = 1000000;
spiParams.dataSize = 8;
spiParams.transferTimeout = 3000;//SPI_WAIT_FOREVER;
spiParams.frameFormat = SPI_POL0_PHA0;

// Initialize SPI handle as default master
spiHandle = SPI_open(Board_SPI0, &spiParams);

and the transfer function:

uint8_t FPCreset(){
	uint8_t bufferTx[4];
	SPI_Transaction spiTransaction;

	PIN_setOutputValue(pinHandle, Board_DIO0, 0);
	PIN_setOutputValue(pinHandle, Board_DIO11, 0);

	bufferTx[0] = 0;
	bufferTx[1] = 0;
	bufferTx[2] = 0;
	bufferTx[3] = 0;
	spiTransaction.count = 4;
	spiTransaction.txBuf = bufferTx;
	spiTransaction.rxBuf = NULL;
	int ret = SPI_transfer(spiHandle,&spiTransaction);
	PIN_setOutputValue(pinHandle, Board_DIO0, 1);

	//Task_sleep(1000 / Clock_tickPeriod);

	return ret;
}

When I use "spiParams.transferTimeout = SPI_WAIT_FOREVER;" CC2650 send the data but never finish.

When I use "spiParams.transferTimeout = 3000;" CC2650 send de data correctly the first time, but the second time never finish.

And when I use "Task_sleep(1000 / Clock_tickPeriod);" CC2650 is blocked when try to executte de command.
