CC430F5137: Communication losses while continuous transmission and reception.

Avinash Tarolkar

Part Number: CC430F5137

Dear All,

I have developed the code for CC430F5137, in that one is Tx and Another is Rx, while i am sending the data continuously after the interval of 20 msec it receives till 10-15 mins and after that communication will breaks and when I give hardware reset to the transmitter it will again start the communication for next 10-15 mins.

Kindly request you to give me a proper solution for this problem asap.

Thanks in advance.

Regards,

Have you tried to run a VCO calibration every minute or so?

When the communication fails, have you tried to see if the Tx frequency has shifted some?

Thanks for reply...

I have checked the frequency at the time of communication fail but is not shifted any more.

Do you have a plot done with 1 kHz RBW at the start of the communication and when it fails?

Have you verified that the sender is actually in the state TX and the receiver is in the state RX?

Do you handle FIFIO over and underflow?

Yes, I have taken all that care in my code and also checked whether receiver is in RX mode and transmitter is in TX mode but still problem is remain...

So when the communication stops, monitoring with a sniffer, does the Tx stop sending?
