    does it do all the computation internally? or is it possible to improve it through software?
    niko20010
    @niko20010
    i never dumped and reversed the firmware
    it is based on the ubiquitous STM32F103C8T6 we all know and love for being on cheap devboards like the bluepill...
    i was shocked though when i read that a single xtensa core of the esp32 is already 3 times as fast...
    Ryan A. Pavlik
    @rpavlik
    really? Like, in actual operation? or just in clock speed?
    niko20010
    @niko20010
    actual operation
    Ryan A. Pavlik
    @rpavlik
    I guess if you have it running at 240, that's 3 times the frequency of f103's 64-72
    niko20010
    @niko20010
    clockspeed is even higher afair
    ahhhhh
    so the guy probably misled
    it is still at least double the speed per core

    @niko20010 OpenHMD cannot add support for something that has closed firmware on-board?
    niko20010
    @niko20010
    there was some discussion on that topic a while back
    they refused to accept a merge because binary blobs with prohibitive licenses were still in it i think
    isopix
    @isopix
    hmmm...but firmware is on-board and there's no need to upload it every connection, right?
    niko20010
    @niko20010
    yes
    isopix
    @isopix
    so I don't understand what's the problem with firmware license then. Nolo has firmware blob too, but they support it
    niko20010
    @niko20010
    @rpavlik i think the relevant bit is that the chip can be put into line mode by attenuating the micboost amp
    so just not turning on micboost should be sufficient i thinjk?

    the only thing left to do is getting rid of the mic bias in that case
    but thats easy

    @isopix philosophical problem. Same reason there's no HDK driver merged, I think - they prefer to do their own sensor fusion, despite the fact the HDK literally is unable to get the non-fused data from the IMU (it does the fusion internally, very well..)
    niko20010
    @niko20010
    the IMU does it internally i think?
    wasn't that the main selling point of the whole BNO series?
    but yeah, the IMU output is rather good
    isopix
    @isopix
    on HDK2? In the past somebody wrote that HDK is a trash, because yaw drift caused by buggy on-board calculations that cannot be fixed in software
    @niko20010: Do you have v1 or v2 firmware on your nolo?
    niko20010
    @niko20010
    no option to check, units ripped apart and raided for parts
    the last time i used that stuff was years ago
    since then i moved on towards avive
    isopix
    @isopix
    ripped because of frustration, or because something broke or you needed some parts?
    hmm...I hoped you will be the one able to dump v1 firmware for me, so I could use it under linux/osvr
    but generally v2 is more stable and maybe could fix your issues with nolo
    Ryan A. Pavlik
    @rpavlik
    Yeah that's the main selling point of the BNO070/080/085
    niko20010
    @niko20010
    frustration, needing parts and it being broken altogether

    @isopix
    Bye and thank you both for help

    Hi everyone
    I don't know if this is the right channel but could I ask for some help?
    My HDK2 Built-in displays are not working/not listing as monitor on Device Manager (even on extended mode)
    I tried the all-in-one installers and manually from configuration tutorials I found on Reddit but to no success
    Should the HDK2 display as a monitor under device manager?
    I'm suspecting faulty hardware (I switched the HDMI cable for one I ensured is working, but nothing changed)
    niko20010
    @niko20010
    Probably the beltbox->HMD cable broke
    Good luck in that case, they were made by semsics which are out of business for a few Years now
    Sensics*
    And yes, in extended it should list AS a monitor
    Stupid autocorrecting phone keyboard

    @FabioFusimoto
    I imagined so, thanks for the reply

    I have the same problem as Fabio. Everything worked fine for maybe month. But now my HDK2 dont display as monitor under device manager. (In extendet or directmode). What is causing the problem with SteamVr giving 422 erorr... Trust me, its not harwdware or cables issue. My brother also have hdk2 and we checked all cables etc.
    Anyone know how to fix that? Please
