Help with packetized serial on SyRen 10?

Not sure if it's the problem or not, but the NewSoftSerial command should be in the setup function I believe.

void setup() {
Serial.begin(115200);
pinMode(txPin, OUTPUT);
pinMode(rxPin, INPUT);
mSerial.begin(9600);
mSerial.print(0xAA,BYTE);
NewSoftSerial mSerial(rxPin, txPin);
delay(1000);
}
