Time required to go from Idle to RX?or IDLE to TX?

Hello guys,

                    im using a cc1200 development module.As per the datasheet,when in RX mode,the module goes to Idle as soon as a valid packet arrives.When i want to receive another packet,the the module must be strobed to RX mode again.Is there any way to avoid this time consuming task.I tried setting the bit RFEND_CFG1.RXOFF_MODE to 11,so that the module goes to RX again when a valid packet arrives.But eventhough,there is not a difference in time taken to receive packets.(Measured using timer).Is it possible to shrink the time by any chance?

                                                                                                                           Thank you

    Hi

    No sure I understand how/what you are measuring. The time it takes to receive a packet will be the same no matter how you get into RX mode at this time is only depending on the data rate and the length of the received packet.

    Using RXOFF_MODE = RX takes the radio to RX mode faster than what is the case if you go via IDLE and strobe RX again. This means that your transmitter can send the packets with a shorter delay in- between and your receiver still be able to receive them. If you are not changing the transmit interval, you will not see any difference on the receiver.
