Hi! If I know correctly, then the MCU can run from the 4MHz clock provided by the RF230. Make sure that your MCU is running on its internal RC oscillator. Also you can add a dummy task that repeatively posts itself to make sure that the MCU never goes to sleep. Please try with this hack to see if it fixes your problem.
Also, can you give a description of what do you observe?
