thanks for the helpful replies
I am now testing an arduino with the nrf24ap2 chip from aliexpress by connecting the tx, rc, ground and rtc pins to 3 digital pins on the arduino and of course the ground
for the software I use a modified version of the uploaded code on this site
http://jbremnant.wordpress.com/2011/11/27/ant-between-msp430-and-android/
to implement the cts/rtc functionality I changed the txMessage function to
digitalWrite(rtspin, LOW); // sets the LED off
for(i=0; i<txBufferSize; i++)
{
_swuart.write(txBuffer[i]);
Serial.print(txBuffer[i], HEX);
Serial.print(' ');
}
Serial.print('\\n');
//50 microseconds high cts
digitalWrite(rtspin, HIGH); // sets the LED off
delayMicroseconds(50);
digitalWrite(rtspin, LOW); // sets the LED off
The whole project can be seen here [file name=antMaster.zip size=3978]

but I still cannot get any signal on my phone
