.TH "rtl_tcp" 1 "0.5.0" RTL-SDR "User Commands"

|
|
.SH NAME
|
|||
|
|
rtl_tcp \- an I/Q spectrum server for RTL2832 based DVB-T receivers
|
|||
|
|
.SH DESCRIPTION
|
|||
|
|
Uses a re-purposed DVB-T receiver as a software defined
|
|||
|
|
radio to receive and send I/Q data via TCP network to another
|
|||
|
|
demodulation, decoding or logging apllication. Written for
|
|||
|
|
and incorporated into the osmocom rtl-sdr project.
|
|||
|
|
.LP
|
|||
|
|
Much software is available for the RTL2832. Most of the user-level
|
|||
|
|
packages rely on the librtlsdr library which comes as part of the
|
|||
|
|
rtl-sdr codebase. This codebase contains both the library itself and
|
|||
|
|
also a number of command line tools such as rtl_test, rtl_sdr,
|
|||
|
|
rtl_tcp, and rtl_fm. These command line tools use the library to test
|
|||
|
|
for the existence of RTL2832 devices and to perform basic data
|
|||
|
|
transfer functions to and from the device.
|
|||
|
|
.LP
|
|||
|
|
Because most of the RTL2832 devices are connected using USB, the
|
|||
|
|
librtlsdr library depends on the libusb library to communicate with
|
|||
|
|
the device.
|
|||
|
|
.SH USAGE
|
|||
|
|
Run this program on a machine with an rtl-sdr supported
|
|||
|
|
device connected and it will provide I/Q data to other applications
|
|||
|
|
via TCP/IP.

|
Use the device argument 'rtl_tcp=10.0.0.2:1234' in OsmoSDR (gr-osmosdr) source
|
|||
|
|
to receive samples in GRC and control rtl_tcp parameters (frequency, gain, ...).
|
|||
|
|
.LP
|
|||
|
|
use the rtl_tcp=... device argument in gr-osmosdr source to receive
|
|||
|
|
the samples in GRC and control the rtl settings remotely.
|
|||
|

|
|||
|
|
This application has been successfully crosscompiled for ARM and MIPS
|
|||
|
|
devices and is providing IQ data in a networked ADS-B setup at a rate
|
|||
|
|
of 2.4MSps. The gr-osmosdr source is being used together with an
|
|||
|
|
optimized gr-air-modes version (see Known Apps below). It is also
|
|||
|
|
available as a package in OpenWRT.
