How to send binary files through USRP and RTL in GNU Radio

Hi, guys, I’m beginner.

I appreciate if any of you have worked with GNU RADIO, for the transmission and reception of files, I need to send an identical binary file in the Source to the Destination.

I am working with a USRP N210 as the transmitter, and an RTL-SDR RTL2832U on the receiver.

I am working with GNURAdio v3.8.0.57

Thank you very much.
