Problem with upgrading from cc2500 to cc1101

Other Parts Discussed in Thread: MSP430F5529, CC2500, TEST2, CC1101

Hi,

So far I used cc2500em msp430f5529 evaluation board with the following settings : RF frequency 2400 MHz, MSK modulation, 250 kbps data rate, 540kHz rx filterbandwidth ( I attached the register setup code) when I used that setting everything worked fine, but when I started to use cc1101em with the following settings: RF frequency 868 MHz, MSK modulation, 250 kbps data rate, 540kHz rx filterbandwidth ( I attached the register setup code for it to) I succeed to receive several message from the sender and after several message the sender got stuck on the line code :

"while (!(TI_CC_GDO0_PxIN&TI_CC_GDO0_PIN));" of the the attached RFSendPacket function and stop sending messages. I will be glad if someone may have any ideas what may cause it and what should I do for solving it.

Thanks

Roy

void RFSendPacket(char *txBuffer, char size)
{
TI_CC_SPIWriteBurstReg(TI_CCxxx0_TXFIFO, txBuffer, size); // Write TX data
TI_CC_SPIStrobe(TI_CCxxx0_STX); // Change state to TX, initiating
// data transfer

while (!(TI_CC_GDO0_PxIN&TI_CC_GDO0_PIN));
// Wait GDO0 to go hi -> sync TX'ed
while (TI_CC_GDO0_PxIN&TI_CC_GDO0_PIN);
// Wait GDO0 to clear -> end of pkt
TI_CC_GDO0_PxIFG &= ~TI_CC_GDO0_PIN; // After pkt TX, this flag is set.
// Has to be cleared before existing
