# sdr-zmq-daemon(1)

ZeroMQ daemon for Software Defined Radios (SDRs)

## NAME

**sdr-zmq-daemon** - ZeroMQ daemon for Software Defined Radios (SDRs)

## SYNOPSIS

```
sdr-zmq-daemon
```

## DESCRIPTION

**Simply start with no options. It will connect to your software defined radio, and start providing IQ data over ZeroMQ on address tcp://127.0.0.1:10444 and provide a configuration interface on tcp://127.0.0.1:10445.** **It is intended to be used together with grdab (Using the 'grdab -z' option).**

**All SDRs supported by gr-osmosdr can be used with sdr-zmq-daemon. It has been verified to work with RTL-SDR, HackRF and USRP B200.**

**It is not a 'true daemon' yet, so you will have to use 'screen' or similar to get it to hide in the background.**

## OPTIONS

**No options available**
