Specifying radio device #230

Closed cloud-rocket closed 2 years ago

cloud-rocket commented 2 years ago

Is there a way to provide an index of USB device to use if there are more than a single radio attached?

Thanks!

You will need to do that when launching the spectrum server:

rtl_tcp, an I/Q spectrum server for RTL2832 based DVB-T receivers

Usage:  [-a listen address]
        [-p listen port (default: 1234)]
        [-f frequency to tune to [Hz]]
        [-g gain (default: 0 for auto)]
        [-s samplerate in Hz (default: 2048000 Hz)]
        [-b number of buffers (default: 15, set by library)]
        [-n max number of linked list buffers to keep (default: 500)]
        [-d device index (default: 0)]
        [-P ppm_error (default: 0)]
        [-T enable bias-T on GPIO PIN 0 (works for rtl-sdr.com v3 dongles)]

The option you'll want is [-d device index (default: 0)]
