Hello
I wanted to have an idea about how to send 1 data (consider it be hello world) from 1 USRP to another using LabVIEW.
Help is greatly appreciated.
Thanks

Hi ManasNyati,
Here is an example of how to transmit IQ data from a text file using a USRP: https://decibel.ni.com/content/docs/DOC-47239. You can pair this example with one of the standard RX examples bundled with the USRP driver to do a simple send and receive test between USRPs.

Hi,
Did you send it ? I want to send ''Hello'' or something like that from NIUSRP 2901 to another one. I searched your examples but it works for numbers and its recevier is for USRP RIO. Could you help me please ?

Hi kebirebardak,
By "Hello" do you mean you want to send a waveform of someone saying hello?

Hello,
I would also like to transmit a "Hello world" text message between 2 USRPs (2921).
From what I understood, the program given as example reads IQ based on the input text file and generates a signal. Is it then possible at the receiver side to perform the reverse operations in order to get the exact text message that was transmitted? Also, is it a problem that I am not using Rio devices?

Hi cristian94,
Yes, the example above reads in IQ based on a file and then generates a signal based on that data. You can capture that signal using a second USRP and one of the receiver examples that come with the NI-USRP driver. It shouldn't be a problem that you are using a RIO device.
How do you want to encode the "Hello world" text into IQ data?

Hello,
I was thinking of transforming the text in a stream of bits and then use a QAM modulation.
In the meantime, I have come across with an example that actually sends a message from one USRP to another using PSK modulations, and packet based digital link: http://forums.ni.com/t5/Software-Defined-Radio/Packet-based-Digital-Link/ta-p/3509866
