Connection of the HackRF One SDR to an Orange Pi Pc2 or Orange PI One Plus running on ARMBIAN or a Radpberry PI.
In console mode, update your system:
sudo apt-get update
sudo apt-get upgrade
Install the library for hackrf:
sudo apt-get install hackrf
Connect the hackrf to an USB port and check it:
If the installation is good, you will get a response “Found HackRF” etc … Sometimes with some USB cables that connect the HackRF, there is no response. Change the cable in this case.
Installation GNU Radio Companion
GNU Radio Companion is a graphical tool allowing you to build radio processing chains very easily without writing a line of code.
sudo apt-get install gnuradio
Installation Osmocom SDR and RTL-SDR Drivers
sudo apt-get update
Installation of the USB library:
sudo apt-get install cmake build-essential libusb-1.0-0-dev
We clone Osmocom in the user’s Downloads folder for example:
sudo git clone https://github.com/osmocom/rtl-sdr.git
Go to the folder rtl-sdr: cd rtl-sdr
sudo mkdir build
sudo cmake ../ -DINSTALL_UDEV_RULES=ON -DDETACH_KERNEL_DRIVER=ON
At this point I sometimes got an error because the pkg-config package was not found. Make:
sudo apt-get install pkg-config
and relaunch the cmake from above.
sudo make install
Osmocom source module installation
sudo apt-get install gr-osmosdr
GNU Radio launch
You have to be in graphics mode to be able to use this superb signal processing design tool. Personally, I use my orange-pi or raspberry in remote mode. I connect to them by enabling VNC in setup and using the VNC extension in chrome on my PC. On a terminal in graphics mode type:
A message “RANDR” missing … is not important.
Error Xterm executable is missing
If you have when launching a model in gnuradio companion a message of the type Xterm executable is missing and if you are on Armbian or Raspbian (raspberry) go to the configuration folder.
sudo nano grc.conf
and add at the end of the file:
[grc] xterm_executable = /usr/bin/lxterminal
First of all, check that the terminal is installed on your machine. Otherwise installed it with:
sudo apt install lxterminal
The HackRF being developed in Open Source can be bought in China at Aliexpress for a hundred Euros. To use it, the Orange Pi solution is very interesting. We forget the Orange Pi Zero which, following the treatment defined in GNU-RADIO, quickly risks running out of power. We are going to move towards 64-bit 4-core processors like the H5 or the H6. I have successfully tested Orange Pi PC2 H5 and Orange PI One Plus H6 for SSB reception and SSB transmission.
The Orange PI PC2 has the following advantages:
- several USB2 if you want to connect different SDRs
- An audio output on headphone jack, useful for an HF receiver
The Orange PI One Plus has the following advantages:
- The minimum required to control a Hack RF or a RTL-SDR from the network (USB, Ethernet 1Gb / s)
- A very low price: less than 30 € with food and transport (Ebay or Aliexpress)
