Raspberry Pi 2 + SDRplay: Setup Guide?

Postby SoulFinderLLC » Wed Apr 06, 2016 6:18 am

Greetings! I am currently in charge of trying to get our SDRplay working on the Raspberry Pi 2 (model B V1.1). The device specific documentation at http://sdrplay.com/raspberrypi2.html leaves much to be desired, as it simply states "None at this time - the Linux documentation may get you some way."

I happen to be somewhat inexperienced with Linux in general and the Raspberry Pi 2 in particular. Nonetheless, I have installed Raspbian Jessie Lite (Version: March 2016, Kernel version: 4.1) and have also performed these commands:

(//Having downloaded Current API Installer: 1.9.2 (includes API 1.8.1 - 11th Jan 2016) (Installer Released: 1st Mar 2016))

chmod 755 SDRplay_RSP_MiricsAPI-1.9.2.RPi.man
./SDRplay_RSP_MiricsAPI-1.9.2.RPi.man

My setup is as follows: The SDRplay is connected directly using USB to one of the ports on the Raspberry Pi 2 itself.

From this point on, I am uncertain how to continue. I have used the lsusb command and it does have the line:

Bus 001 Device 005: ID 1df7:2500

This seems to confirm that the device is being recognized, at least at a basic level.

Now, I have previously had success getting the SDRplay to work on other Linux devices (using Intel x86 CPUs, never on an ARM based device, having tried on the BeagleBone Black), so I am not totally clueless.

My question is thus:

What are the minimum steps needed to get the SDRplay working on the Raspberry Pi 2? I would like to at least be able to write my own C++ code, making use of the API Specification, and to have some kind of existing SDR software running to test/play around with.

I hope this post can be helpful to others who have the same level of knowledge as I do here, thanks!! :D

First of all make sure udev is setup correctly so that you have the right permissions to talk to the RSP. Check if you have the following file, if not create it using sudo nano...

/etc/udev/rules.d/66-mirics.rules

it should just have one line in it...

SUBSYSTEM=="usb" ATTR{idVendor}=="1df7" ATTR{idProduct}=="2500" MODE:="0666"

Then you will need to restart udev...

sudo service restart udev

and then disconnect and reconnect the RSP.

Then you have 2 options, to either install SoapySDR/SoapySDRPlay - this is a generic control library that supports a variety of hardware including the RSP. To build/install it see: https://github.com/pothosware/SoapySDR/wiki and https://github.com/pothosware/SoapySDRPlay/wiki

Once both of these are installed, typing SoapySDRUtil --probe=sdrplay should produce an output without any errors.

Alternatively you can program for the API directly. On our Raspberry Pi page (http://www.sdrplay.com/raspberrypi2.html) you will see the API specification and an example of the control code in the back. There are also some example code on our github repository: https://github.com/SDRplay showing how we have controlled and received samples from the RSP.

If you want to use the dump1090 ADS-B decoder with the RSP, the version to use on the Raspberry Pi at the moment is: https://github.com/SDRplay/dump1090_sdrplus - there is a build_libs.txt file to explain what needs to be built for that application.

If you have any specific programming issues related to the RSP, please let us know and we'll try to help you. An email to support@sdrplay.com is the best way to do that.

Best regards,

SDRplay Support

I appreciate this reply, it helped exactly and everything worked (I got it working a couple weeks ago, just didn't get around to this reply until now)!! I am in the process of writing a detailed guide so that people in my position, in the future, won't feel so lost. If it is good enough, maybe it can replace the "None at this time - the Linux documentation may get you some way." line under "Raspberry Pi 2 Specific Documentation" on the main site. I will post it here later. :D

Hi SoulfinderLLC,
I am struggling to get the RSP working with my Pi3.
Using the SDRPLAY instructions gets me so far then nothing.
Is there a simpler setup guide available for folks with very little knowledge of raspberry Pi?

I am sorry for never getting around to posting the guide I had promised. I don't know to what extent the instructions for the Pi2 would transition to the Pi3, but I will try to have something written up soon.

The very day your reply came in, this forum and the greater site all went down and I could not access anything. I then forgot about it, so sorry for the late reply.

Hi
I made various test and comparisons between Orange PI and Intel based mini PC's for SDR.
Using gqrx under Linux and SDRtouch under Android and various softwares under Windows 10.
My conclusion is that Intel devices are much more suited due to the mathematical computations involved.
May be a good use for PI would be to stream the complete output of the receiver on a gigabit network.
I have yet to investigate that .
For narrow band uses like with a fun cube dongle the PI is OK but even decoding an FM stereo signal is
hard to do and needs good cooling of the CPU.

Did that setup guide ever get published somewhere? I am similarly stuck.

I installed the API. Ran LSUSB, see the SRDplay in a USB port. Checked UDEV, and the device is listed in the rules. Installed and compiled SoapySDR. Unplugged and plugged the SDR. Everything seems right.

Next I enter "SoapySDRUtil --probe=sdrplay" and get a console screen listing driver=null, hardware=null, Channels: 0 Rx, 0 Tx; and Timestamps = NO

huh? Seems that I must have missed an important step somewhere...

There are two parts of the SoapySDR and the output you're getting suggests 'SoapySDRPlay' isn't installed. I pasted how that install went for me:

John - THANK YOU!

I followed the instructions you provided and am now getting some valid results from SoapySDR.
