We have come a long way with our platform support in the past couple of weeks. We have added and tested DC calibration, sped up FPGA programming, added a new bladeRF-flash tool and several streaming examples, and moved most of the API over to asynchronous calls.

To benefit from these changes you must upgrade your device, instructions on upgrading the bladeRF can be at .

Within the next week we will merge the SPI flash based FPGA loader, which allow the bladeRF to not require a computer to load the FPGA and in effect run headless. Afterwards, our focus will switch to back to merging in timestamped transmissions support, this will enable OpenBTS to run on the bladeRF.

There is now a Windows based installer for the bladeRF that will install all of the relevant drivers, user mode utilities, and FX3/FPGA images. The file can be directly downloaded from .

We would also like to thank the community contributors that have provided patches, and pointed out issues to us. (Bugs and requests for features can be filed via Github at ).

Lastly, RTucker (HoopyCat) has created an autobuilder for the FX3 and FPGA images. The autobuilder recompiles everything on every commit that is merged into master on Github. The autobuilder can be found at .

We have spent the last week working on platform support. Windows and Linux installation procedures have been updated and can be found at installations should flow very similarly to Linux).

We are also trying to debug a SuperSpeed USB3.0 issue that occurs with libusb and certain XHCI controllers. So if at all possible, if you have an ASMedia or Renesas XHCI and are running Windows, could you please tell us via Kickstarter, or email ( ) if you bladeRF-cli is able to see the device?

As you might have guessed bladeRF-cli now has interactive support on Windows as well!

There is also another firmware upgrade available (v1.2) that has minor fixes that is avaiable at .

A community member who goes by handle Acceleron uploaded designs for a case for the bladeRF to thingiverse this past week ( ). We also uploaded the mechanical DXF files to bladeRF to our site in case anyone would like to get specific measurements of the board, .

We spent a great deal of time integrating our libusb changes into our master branch this past week. From all of the regression testing we have done, libusb support seems to be stable and working pretty well on Linux. There are a few Github issues regarding OSX and Windows that are being worked out this week, so hopefully by the next update we’ll have good news for all three platforms (Windows, Linux, OSX). Libusb and OsmoSDR support is on its way but we still suggest that users use the Linux driver until the libusb async support that has been added is made to work with OsmoSDR.

Lastly, if you haven’t received your unit and haven’t yet placed an order claiming your reward please look through the Kickstarter messages we sent a while ago to see how to go about this process.

bladeRF is now officially in stock! Thank you all so much for backing us and making this project a reality.

For those of you that have already claimed your rewards by placing an order on our site you should have received your unit by now, been sent a tracking number, or been sent an email with questions or been given a personalized update. If you claimed your reward and none of these things have happened, please reply to the order confirmation email you received from our site. If you haven’t claimed your order, please check your Kickstarter message box to see how this should be done.

If you are a developer or enthusiast backer, we will contact you shortly about additional steps we have for fulfilling our commitments to you.

We’ve been working tediously on libusb support ( ) that so many of you have asked us for. Once libusb is stable the codebase will default to using libusb as the default method of communicating with the bladeRF. The driver will remain available for advanced users who need low latency, and zero copy buffering. Libusb support should be finished soon, and then we’ll finally have time for some really fun things.

Lastly, we’ve been asked if we will continue our weekly updates, and the answer is yes! There are many projects and updates we would like to keep all of you up-to-date with.

PS. Greetings to everyone we met at DEFCON this year!

If you will be attending DEFCON this weekend, come to our talk at 8/3/13 – 17:30 in the Wireless Village or swing by our booth in the vendor area!


Here is a teaser of the last thing we were briefly able to work on before heading out to DEFCON (yes, it is the first ever SDR-UAV! )

bladeRF Software Defined Radio - Unmanned Aerial Vehicle


It doesn’t yet fly, but it will. The headless mode code will be released shortly. Anyone with expertise or anyone who is interested in modern and/or robust controls please contact


The bladeRF is being powered through the GPIO board by the brushless DC BEC (battery elimination circuit).
