Hi Achintha, Janos is only partially right. You can disable the software CCA check (which is doing an RSSI check), but the hardware can still prevent you to send a message. If it RF230 is in the process of receiving a packet then you cannot disturb it with a transmit, it will continue receiving the packet.
