Hi I am pretty new to UHD. I was looking for some example programs which can send and receive a text file, and I came across two programs in the website (http://code.ettus.com/redmine/ettus/projects/uhd/repository/revisions/master/show/host/examples) named rx_samples_to_file.cpp and tx_samples_to_file.cpp.
I ran these programs in USRP1. and gave the following arguements: 1)./tx --rate 500000 --freq 10000000 --file rr.txt[this is the name of the file i transferred] 2)./rx --rate 500000 --freq 10000000 --file r1.txt[this is the name of the file where i store the received text] When I tried to transmit and receive some sample text files, the sender transmitted it correctly, but the receiver is not receiving anything. When I opened the received file, I found that the file was more than 10MB and there were some gibberish text in the file. The programs specify in the help options that they transmit and receive binary samples, so I don't know if I am working with the correct programs or if I am giving the correct arguments while running them. I also need to change the modulation schemes for different channel environments. Actually, I am working on adaptive modulation schemes in my experiments. However, I don't find an option to change the modulation schemes in UHD. (I saw those options in python based non-uhd codes, e.g. benchmar_Rx and benchmark_Tx). Are there any programs like that in UHD codes that allow change of modulation schemes? Your feedback will be very appreciated.
