XBee Features

Hello, I am a beginner to use XBee. May I know can we disable the features of Frame Check Sequence (FCS) in the XBee? Because that I am doing a project on FEC technique and I would like to disable the FCS on XBee. Thanks for your help.

I’m not sure about this.
But the API functionality is inbuilt in XBee modules.
Maybe Digi people can help in this.
