Radio and Uart

Hi,

i wrote a radio code. My code dunction well. Now i want to add my uart code and see my data, coming from the one uC, on the pc. But i get only wrong data. If i test my code with SmartRF Studio7 than i can see that my code is right. Also i get the right data from the uC. 

I configurate the baudrate to 1.2kHz for the radio and for the uart. But i see only wrong data coming.

Here my code:

SLEEP &= ~SLEEP_OSC_PD_BM; 
while (!(SLEEP & SLEEP_XOSC_STB_BM));
CLKCON &= ~CLKCON_OSC_BM; 
while (CLKCON & CLKCON_OSC_BM); 

SLEEP |= SLEEP_OSC_PD_BM; 

U0BAUD = 163; 
U0GCR = (U0GCR&~0x1F) | 5;            //baud rate 1200

 
PERCFG &= ~0x01; 
// P0SEL.SELP0_2/3/4/5 = 1 => RX = P0_2, TX = P0_3, CT = P0_4, RT = P0_5 
P0SEL |= 0x3C; 
P1SEL &= ~0x3C;

U0CSR |= U0CSR_MODE; 

U0UCR &= ~U0UCR_START; 

U0UCR |= U0UCR_STOP; 

U0UCR &= ~U0UCR_SPB; 

U0UCR &= ~U0UCR_PARITY; 

U0UCR &= ~U0UCR_BIT9; 

U0UCR &= ~U0UCR_D9; 

U0UCR &= ~U0UCR_FLOW; 

U0GCR &= ~U0GCR_ORDER;

RFIF = 0x00;
RFTXRXIF = 0;

EA = 1;

while(1)
{
RFST = 0x02; 
while (!RFTXRXIF); 
RFTXRXIF = 0; 
length = RFD; 
rxBuffer[0] = length; 

UTX0IF = 0; 
U0CSR &= ~U0CSR_TX_BYTE; 

for (uint8 j = 1; j <= length + 2; j++) 
{
while (!RFTXRXIF);
RFTXRXIF = 0;
rxBuffer[j] = RFD; 
uart[j] = RFD;

} 
while ((RFIF & 0x10) == 0); 

IEN2 |= IEN2_RFIE; 

while(TX_Z<=length)
{
U0DBUF = uart[TX_Z];
TX_Z++;
}
TX_Z=1;
IEN2 |= IEN2_UTX0IE; 

}

#pragma vector = RF_VECTOR
__interrupt void RF() 
{
RFIF = 0;
IEN2 &= ~IEN2_RFIE; 
}

#pragma vector = UTX0_VECTOR
__interrupt void UTX0(void)
{
UTX0IF = 0;
if (TX_Z > length)
{
TX_Z = 0; 
IEN2 &= ~IEN2_UTX0IE; 
return; 
}
IEN2 &= ~IEN2_UTX0IE; 
}

Please help!
