[Discuss-gnuradio] Help needed to transmit text that werent encoded in program

[Alice Lee]

Hi,
 
I've been tasked to work on gnuradio and usrp recently and below are some of the things that i need to implement.
 
I have got 2 usrps over here and i needed to use one as a transmitter and the other as a receiver. For the transmitter, i need to use the program to open a new window where i can enter text to be transmitted and then with just a click on a "send" button, the program will actually transmit what ever text that i had entered in the window.
 
The receiver will then receive and decipher it to extract the text which i had transmitted.
 
I have gone through the benchmark_rx.py and benchmark_tx.py and tried to modify the codings but realised that there seems to have alot of interferences between the 2 usrps even though they are place close together. If i just transmit once, the receiver might not be able to even receive it.
 
The other problem is writing the codings to actually open up a window with buttons that i can apply controls to it so that with a click on the "send" button, it will trigger the usrp to start transmitting.
 
Is there are such available programs or maybe something which i can have as a reference to?
 
Thanks.
 
Alice
