Hi,

Whether the below example checking the CRC, before blinking the LED ?

Thanks,

Yes, the following is set:
RF_cmdPropRx.rxConf.bAutoFlushCrcErr = 1;

To check how many packets that you have received with a CRC error you can add rxStatistics to your code

tatic rfc_propRxOutput_t rxStatistics;

RF_cmdPropRx.pOutput = (uint8_t*)&rxStatistics;

After you have received a packet (or several):

Display_printf(displayHandle, 0, 0, "Number of OK packets: %d", rxStatistics.nRxOk);
Display_printf(displayHandle, 0, 0, "Number of NOK packets: %d", rxStatistics.nRxNok);

Hi TER,
So by checking the LED pattern, we can find whether we received the correct packet or not, right ?

Thanks

Yes. But by just looking at the LEDs it will be easy to miss if the LED didn't blink 1 out of 100 times (as one example).

Hi TER,

Yes.. Correct. Actually I am doing a range test with a custom made board with cc1350. We just want to make sure that if the LED is blinking, we are receiving the correct packet without any CRC error. So we hope, that example will be good for initial testing. Later we can go for number of packet we missed due to CRC as you suggested in this post.

Thanks.

For range testing you should also look into the rfPacketErrorRate example
