What type of component for receiving IR?

ExplodingWaffle

I am trying to build a remote with learning feature using BL702. For the IR peripheral, what type of receiver is supposed to be used? Non demodulating (photodiode, phototransistor, TSMP58000) or demodulating like TSOP38238? this is not 100% clear from the datasheet or sdk code. Would like to be able to learn any signal regardless of modulation frequency. Thanks

Any ir receiver can be used, the common one is vs1838.
