Hi,

On the L01, you have:

EN_CRC register to enable/disable CRC.
CRCO register: to select number of bytes for CRC

On the nRF51 you configure CRC using CRCCNF, CRCPOLY and CRCINIT. Please make sure CRCCNF (2 bytes, address included) and CRCPOLY (0x11021UL) are matched.

Hi, Thank you for your help.Now I have another confusion.In my case, I can't verify the parameters of the 24l01, as it has been a product as a tag. Now I verify the parameters in the 51822 to match the 24l01.In the 24l01 the CRC is two bytes.Now in the 51822 I configure the CRC is two bytes too. where can I configure else?please tell me,thank you!

@Linda: Could you upload your code ? Could you verify that the L01 is configured with matched CRC ? In the example I sent you in the other case, output on RX is only executed when there is CRC matched and I found no problem with the nRR24LE1.

One more note, when you post question with code, could you please use "Code" feature in the tool bar so that it's easier to read ?
