Ubuntu App Store Progress

Ubuntu App Stores

Right from the outset, a key element of the software strategy for LimeSDR has been integration with the Ubuntu app store, in order to make it easy to quickly and securely deploy applications for all manner of different wireless systems. Applications which might involve many components and numerous software dependencies would thereby benefit from the simplicity of an app store model.

In actual fact, two app stores have now been set up: LimeNET, for reference applications from Lime Microsystems and certified apps from partners, and the LimeSDR store for community contributed apps. While applications published to the former will be subject to a certification process, the basic criteria for apps to be published to the latter is that they provide support for LimeSDR hardware.

Why two app stores? LimeNET is intended for use by network operators, system integrators and enterprise organisations, and will contain a smaller selection of rigorously tested, carrier-grade applications, alongside reference apps. Whereas in principle anyone will be able to publish apps to the LimeSDR store, provided they meet some simple criteria. In addition, there is the standard Ubuntu app store, which is not specific to LimeSDR, but may still contain useful applications for use with LimeSDR.

It should also be noted that, since a Linux system can only be set up to use a single app store at any point in time, the LimeSDR store has been configured to inherit apps from both LimeNET and the main Ubuntu app store. What this means is that if a system is configured to use the LimeSDR store, it is able to install apps that have been published to any of the three stores.

In order to make it possible to browse and search the available apps without having to first configure an app-enabled system, two websites have been set up:

Now that the stores are configured and the above websites live, over the coming weeks and months we will be working internally and with partners to package and publish additional applications. We will also be putting together guidelines and a process to enable community contributions to the LimeSDR store.

Ubuntu Core Images

Configuring a classic snap-enabled system, such as desktop Ubuntu Linux, to use one of the app stores is as simple as setting an environment variable and restarting snapd. However, Ubuntu Core — which was designed with network, IoT, and other devices in mind — requires use of a custom operating system image that is permanently linked to a particular app store. Work is already under way on creating new Core images and we hope to be able to share them with you soon.

GitHub and PPA

Finally, we’d just like to note that while proprietary applications can be published to the app stores alongside open source ones, the LimeSDR platform itself, associated drivers and reference applications will continue to be fully open and with sources available on GitHub. In addition to which there are no plans at present to stop providing classic Ubuntu packages via the Myriad-RF PPA.

$299

LimeSDR

The LimeSDR is based on Lime Microsystem’s latest generation of field programmable RF transceiver technology, combined with FPGA and microcontroller chipsets. These connect to a computer via USB3. LimeSDR then delivers the wireless data and the CPU provides the computing power required to process the incoming signals, and to generate the data to be transmitted by the LimeSDR to all other devices.


$99

Acrylic Case

A layered acrylic case to protect your LimeSDR. Can be used with either USB Type A or micro USB Type B. Antenna not included - separate purchase available.


$599

LimeSDR with Aluminum Kit

Start developing apps based on Lime Microsystem’s latest generation of field programmable RF transceiver technology. This board comes with fancy aluminum casing. The board will be delivered with turnkey support for a diverse range of SDR ecosystem software, a powerful API and rapid prototyping environment. All the boards in this category will come with a fancy Aluminum casing coated with high quality material, cables, and antennas for a quick set up.


$85

Four Antenna + Cable Pairs

Omni-directional antenna set, covering frequency ranges 800-960 MHz, 1710-2170 MHz, and 2400-2700 MHz. Includes U.FL to SMA cables.


$169

GPIO Board

This stackable expansion board for the LimeSDR provides individually settable, bi-directional level-shifted I/O for FPGA GPIO 0-7. Each I/O has a high-voltage and power Darlington drive stage suitable for inductive loads, such as coaxial relays. LimeSDR not included.


$79

Hacker Case

This custom acrylic case accommodates both a LimeSDR and a GPIO Board, and includes SMA connectors for all RF ports, two SMA connectors for clock I/O, and a 40 mm cooling fan. LimeSDR and GPIO Board not included.
