[eZ430-RF2500] After a while I get CCA failures

Other Parts Discussed in Thread: CC2500

Hi,

I've bought several eZ430-RF2500 boards and programmed them with my software using the IAR Embedded Workbench IDE. I've made a simpel application that transmits data using the RF chips. One eZ430 board is hooked up to a battery power supply and the other one is hooked up to my PC. When I use the software the RF chip on the battery supply responds good, but after a while it doesn't respond anymore.

When I debug trough the code I noticed that the CC2500 code doesn't call my MRFI_RxCompleteISR function anymore. When I try to transmit a packet using the MRFI_Transmit method in the CC2500 code the return value is 1 (MRFI_TRANSMIT_CCA_FAILED -  transmit failed because of CCA check(s)).What could be the reason that the CCA checks fail suddenly?
