Read incoming RF packet carrier offset

[Mark]

Hi,

Is it possible to access the relative carrier offset of a received RF packet from the radio?  Specifically, I'm wondering of there's a register I can access that has this info in some form.

Thanks!

Hi,

by standard means - no, but you can sample I/Q from the whole packet and measure an offset of average frequency. For transmitter and receiver tuned at the same frequency and 50/50 distribution of 0 and 1, there will be zero offset.

Thanks, worst case I can do something like that.  I'm hoping someone from the Nordic team knows of a hidden register with this info--most radio ICs I've used before had a frequency error register.

Hi Mark, 

The related info about the register is nonpublic. Sorry for the inconvenience.

Hi Amanda,

No problem, I'll put in a private ticket.

Thanks!
