A very quick update on this. I recently pushed the first release of the analog_io_lib to Github. With this library you are now able to simultaneously transmit Bluetooth Low Energy packets with nRF24 proprietary RF packets.

The interface is the same as the Serial.print API in Arduino so it is super simple to use. Check out the sample code:

Dual Mode Tx Example:

#include <analog_io.h>
#include <SPI.h>

uint8_t x = 0;
analog_io radio(P3_5, P3_6, P2_5); // CE, CSN, IRQ

const uint8_t txaddr[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0x01 };

void setup()
{
  SPI.begin();
  SPI.setDataMode(SPI_MODE0);
  SPI.setBitOrder(MSBFIRST);
  
  radio.begin();  // Defaults 1Mbps, channel 0, max TX power

  radio.setTXaddress((void*)txaddr);
}

void loop()
{
  // put your main code here, to run repeatedly:
  radio.print("TX #");
  radio.print(x);
  radio.flush();
  
  delay(250);
  
  radio.print("Beacon #");
  radio.print(x);
  radio.flushBle();
  x++;
  delay(250);
}

RF Receive Example:

#include <analog_io.h>
#include <SPI.h>

analog_io radio(P3_5, P3_6, P2_5); // CE, CSN, IRQ
const uint8_t rxaddr[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0x01 };

void setup() {
  Serial.begin(9600);

  SPI.begin();
  SPI.setDataMode(SPI_MODE0);
  SPI.setBitOrder(MSBFIRST);
  
  radio.begin();  // Defaults 1Mbps, channel 0, max TX power

  radio.setRXaddress((void*)rxaddr);
  
  radio.enableRX();  // Start listening
}

void loop() {
  char inbuf[33];
 
  while (!radio.available(true))
    ;
  if (radio.read(inbuf)) {
    Serial.print("Received packet: ");
    Serial.println(inbuf);
  }
}

The library works both with Arduino+a nRF24 module or Energia and my MSP430 Sensor Node hardware. Check it out here:

Also if you are using a MSP430 Sensor node, here is info on adding support for this hardware to Energia:
