Hi,

The over-the-air symbol rate is 1Mbps for 500kbps setting so the spectrum will look the same.

It is confusing to me!

Do you mean that CC2640R2F doesn't support 500K rate?

Hi,

Yes, it supports 500kbps rate. The concept is that the underlying data bit is coded with 2-bits of information which halves the effective data rate but the on air "symbol" rate remains 1mbps.

So it looks like 1Mbps waveform,but the reality data rate is 500kbps,right?
