How to completely shut down the RF part of CC2541?


KAKU2

Hello, all!

I currently use CC2541 as a microcontroller to control some peripherals, so the RF circuit pins RF_N and RF_P of CC2541 are left unconnected. The program does not open Bluetooth related content. After starting, the spectrum analyzer detects a 2.4G signal. In this case, is it possible that the 2.4G signal is generated by CC2541? If it is, how to completely shut down the RF part of CC2541?

Hope for some good ideas!

Thanks in advance!
