Xbee S2C with Xbee Shield (MCS01407S)

Good Day!!

I am new in using Xbee. I already finished configuring my 2 Xbee using XCTU and it is in API mode.

I want to send data via Serial Monitor using Arduino Uno with an Xbee Shield (MCSO14O7S) and the data will receive by Raspberry Pi 3 Model B.

I was wondering, what code shall I use to send data to the Raspberry Pi?
