Welcome to OpenTXU

Welcome to OpenTX University. This site is part of an (overly?) ambitious project to provide an online learning environment to help you explore the brave new world of what we call the Developer’s Version of OpenTX.  We call it the Developer’s Version because it’s slightly different from the OEM version shipped by FrSky on the Taranis and Taranis Plus transmitters.  They’re similar, but not exactly the same. Don’t worry if you’re a newcomer (affectionately known as a NOOB). Don’t worry if you don’t even know what open source, OpenTX, or OpenTX Companion are. We’ll take care of that shortly.

scott_quotewThe site is organized along the lines of a university with Undergraduate and Graduate programs as well as a Division of Continuing Education to handle both software and hardware upgrades. We even have a “Special Interests” section for any groups with common interests who need a place to hang out.

Each section contains “classes” that have been designed and contributed by users just like you. However, it’s different from other “schools” in that you don’t have to register, there are no fees, no grades, and no class attendance requirements. Ya’ can’t beat that with a stick!

What do you need to get around here? Well, you should probably at least know where the switch is on your computer, and it’s really handy to be familiar with your computer’s file system structure and basic operations such as downloading, installing, copying files, etc. If you know how to do that, you’ll be fine.

You’ll be shown how to do 90% of what many of us need to do by using only the transmitter. However, many (May I say ‘most?) users have discovered an absolutely marvelous little piece of free software called OpenTX Companion. OpenTX Companion allows you to manage almost all of your radio functions from your computer. That’s when things really get interesting! It’s the other half of this game changing experience, and has its own series of classes.

OK, enough chit-chat. Let’s get started. Click one of the buttons in the menu at the top of the page and start browsing through what’s offered. The whole idea is for you to take away from here what you can use and ignore the rest!

  1. Just registered today after lurking for the last few weeks. I want to thank those that have already provided me with a world of new found knowledge. Painless 360, R Scott Page, Leonard MacKey, you guys have have made ownership of my new Taranis plus so much more enjoyable. I can only imagine the time and effort you guys spend to make our hobby so awesome. Thanks Again

  2. Just Joined up today. have logged about 20 minutes on my Taranis Plus. I am SO MUCH a noob. i’ve been reading up & got my companion 2.1.7 up & running. but my Taranis says it’s @ bootloader 2.1.6… much more to read & explore – I’m pretty sure that this site has EVERYTHING i’ve been looking for in order to get over my fear of this Transmitter. thanks.

    • Hi, Russ, and welcome to the asylum!

      Don’t be concerned about the bootloader version for now. Depending upon which version you have installed and how you got there, that’s normal. The big this is to realize that there are two “families” of firmware, the OEM version from FrSky that comes shipped from the factory, and OpenTX, which we refer to as the developers version. It’s the primary focus for most of us.

      Be sure to stop by if you have questions. Can’t guarantee the quickest of response times, but we try.

  3. Hello
    I am getting problems with dfu-util 0.7.

    Some info:
    I want to upgrade my Taranis X9D Radio Control firmware.
    dfu-util 0.7 (installed in my MacBook Air and also OpenTX Companion 2.1.7).

    When I try to update the new Taranis RC firmware (opentx-taranis-en.bin) I always get this message:
    No DFU capable USB device found
    “your driver does not seem connected to USB or the driver is not initialised”

    My DFU-util driver it is installed, I triple check it, About this Mac>System report>Software>Installations
    I install Companion 2.1.7
    I have a Taranis X9D (prior the Plus)
    The Firmware
    opentx-r 2940
    EEPR: 215

    I read that some MacBook Air have problem with the USB 3 so I also try in my MacPro with USB 2

    I find gnumonks.org and the http://dfu-util.sourceforge.net where I find a new dfu-util version (v0,9)
    I am not very technical I download dfu-util 0,9 but I don’t know how to install or if it will be the solution.

    Any help very appreciate
    Thank you

  4. Hi,I just bought a new LiPo battery for my XD9+ and now it won’t turn on at all, not even in boot loader mode. I have tried the original battery, and no power at all. After letting it rest for a few minutes and plugging the battery it sometimes flashes the screen a few times then it goes dead. Also some interference nice coming out of the speaker. Any ideas? I have tried searching the forums and have not found a solution.

    • Hi, Jerry! Welcome!

      First, the obvious. Did you by the replacement FrSky battery from Aloft or another reputable dealer? If not, double and triple check the polarity and pin assignments. If you’re getting screen flashes, the polarity is probably correct.
      If you purchased it fro Wayne at Aloft, you might try contacting them. They’ve seen a lot more of this type of problem than we have.

      Sorry I couldn’t be of more help.

  5. Hi,
    I’ve been trying to flash my Taranis x9d+ with non EU firmware but can’t seem to download the .frk file to my windows 8 laptop. A full page of gibberish follows after hitting download. I want to transfer the file to the SD card then update through the receiver. Any help would be really appreciated.
    Thanks.

    • Hi, Jason! Check to make sure that you haven’t tried to flash the wrong version of firmware to your TX. In Companion –> Settings –> Settings there’s a drop down selection box for “Radio Type.” It needs to be set to your particular radio (Taranis, Plus, X9E, etc.) BEFORE you download your firmware. Once you have the correct firmware, try re-flashing. That usually does the trick….most of the time….maybe. Seriously, it’s worked for me (more than once…don’t ask!) as well as many others.

    • Hi, ksped!

      You should ALWAYS have a copy of those two stored somewhere. You never know when you’ll need it. You may not ask me how I know that. 🙂

  6. Hi people, I have been a lazy bum and not upgraded the firmware on my Taranis
    its currently at 2.0.9 – using the update routine on companion gives 2.0.17 as the latest release – but when I try to apply that release it tells me its not compatible…. what do I need to do?

    Cheers

    Dave

    • Hi, Dave! Welcome!

      Hm….actually, the latest releases are either: A) v2.1.6, or B) A new pre-v2.1 that was posted on Jan. 3rd that I have yet to look at: v2.0.18. Either are available from the OpenTX Downloads page (http://www.open-tx.org/downloads.html). I, also, have been a lazy bum and have no clue right now what the differences are between v2.0.17 and v2.0.18. My sense is that they just cleaned up a few minor things, as my sources tell me that the development team is hard at work on the new Horus firmware and tweaking the v2.1+ iterations of the Taranis firmware.

      There may have been an EEPROM change between v2.0.9 and v2.0.17, but if so, my poor addled brain is so fried that I can’t recall. Even that should not cause any major problems, because the EEPROM automatically reformats the first timer you turn on the updated TX.

      If all else fails, try installing the Zadig driver for Windows (http://zadig.akeo.ie/) and then giving it a shot.

      Additional comments most welcome!
