First Channel and Last Channel of CyFi

Question: What is the significance of the parameters First channel and Last channel in CyFi user module?



This parameter controls the low limit and high limit  of the RF channel range used by the CYFISNP protocol to ensure regulatory compliance by preventing or reducing out-of-band RF emissions that may occur depending on RF circuitry design (for example, nonlinearities in an external power amplifier may cause out-of-band RF emissions).
