sudo make
sudo make install
sudo ldconfig
Be aware that the build process that occurs during these steps will take several mi-
nutes on the Pi. The build script will update your status as it progresses.
When the install is complete, you need to copy a set of device rules for the RTL-SDR
into the
udev
configuration directory:
$ cd /opt/rtl-sdr/
$ sudo cp rtl-sdr.rules /etc/udev/rules.d/
These rules will ensure that your RTL-SDR device is properly configured when it is
inserted into your Raspberry Pi.
If you haven't already done so, go ahead and plug in your RTL-SDR device. Then, reboot
the Raspberry Pi to ensure that the system cleanly and correctly loads the drivers on
startup:
$ sudo reboot
Now, you should run a test script to make sure Raspbian is using the driver and can
receive data from the RTL-SDR device:
$ rtl_test -t
If all is well, happy messages will appear and test the modes of the RTL-SDR device:
$ rtl_test -t
