extremely bright led!

    any follow up on this here?

    I ask a question to Zidoo team: some users says that led is too bright, and, in my personal case, is not too bright, but normal (not disturbing blue).
    May be that in the production of X6 Pro there are different HW configurations?
    Is a legitimate suspect based on so different behavior reported by users on the same functionality (i.e. WiFi slow for someone and speedy for other, address not assigned by router DHCP only for X6 for someone and no problem for others...)
    I know that also Big Android device vendor like Samsung sells the same device in the same country with rather different HW configuration, but let clients knowing this may be useful, or at least honest.

    TIA!

    no answer to this from zidoo?????

    no.. no answer .. all my bugs were not fixed as well .. so @grummel2005 , we have this in common :(

    Maybe? However, led brightness does not bother me - I didn't realize that led might be too bright for some users. What I have seen is that the led has same brightness level as what my Topfield PVR digibox's led has.

    Hi :)

    Any updates on this?

    what i can say is that i think @gonjan had a good point ..
    i mean: my nvidia shield let me control the brightness of the led

    Hi all:
    as i say before, it could not to control the brightness by the soft.

    :) .. i think we did understand that this is not possible at this moment :)

    the question is more: will zidoo implement a software-functionality to dim the led?
    • if yes: will it be in the next firmware release?
    • if no:
      • why not?
      • please add this to your change request feature list

    they do not want to do - as i understand
    i cannot understand why, because it is with not a big problem possible

    because when in the standby mode, the cpu it power down, and the led could not be controled yet.
    the led is only one pin to control on/off, the software could not do everything.

    So the LED is directly connected to a pin of the CPU?

    Is (at least) a dual color led, with one pin for the red light ad one for the blue light, so I suppose is connected to two pins. Or are two different leds?

    Anyway, because led is turnet on only when CPU is powered on, CPU should be able to control led intensity in the same way car rear red led parking lights/stop lights (usually is a sigle unit) change intensity from low (parking) to high (stop) using Pulse Width Modulation, i.e. toggling led power very quicky (to avoid annoying flickering is best if frequency is more then eyes persistence, like in raster TV, so 50 or 60 Hz is enough) and reducing or increasing the "on phase" duration compared to "off phase" to change intensity.
    To avoid interference you may sync this modulation frequency with another relevant video (or audio?) signal, but a little experimentation should be enough to verify feasibility and possible interferences.

    Of course I'm not sure if your HW is capable of this (I've not X6 schematic ;) ), but I was able to do the same on a complex device I've designed for the company where I'm employed to change led intensity, and was a device with with a very old CPU...

    spring:
    when blue LED is on the device is not on standbye anymore :)
    so if the device is in "working mode" you can handle the blue LED right after start
    read the statements above the thread - there are some solutions to this :)

    the only place where I could see an on-off-able LED in so many stupid devices I owed over the years, is the LG tv-set, you just go to the menu and kill the bastard, that's it.
    now, regarding the zidoo device, sometimes I find it too bright, too, but I definitely won't like it without any light, I simply need to know when is on and when is off, since I am using it as a torrent box, too.
    the guy from staff explaining the led only have red/blue/off controls might be right. for dimming you need to alter the current, first of all, and also the LED itself should be able to lite with less power. as far as I know, not ALL the LEDs are dimmable. some won't lite up with less power than specified, others will alter the colour depending on current, and so on.
    I'm afraid this is a hardware problem, and it won't be better solved than a patch of coloured tape / fancy sticker..

    since about 5 years ALL LEDs are dimmable.
    only older - e.g. in older LED lights for rooms - are NOT dimmable, but those are old and should not bought anymore - but they are in the market
    LED is NOT LED, there had been massive changes in the last years

    the LED powered light bulbs are a different matter, they do have a specialised driver onboard which alters the voltage (and not all of them).. not the case in our zidoo..
    not looking for contradictions at all, but i'm quite sure what you need cannot be achieved by software, not this time.
    if you're any good in electronics or have such a friend, maybe you can electronically alter the system, either by replacing the LED with a less brighter one or better installing a resistive dimming montage just before the LED power-0n pin. which will remove your warranty, of course, but will solve the issue.
    we better fight for real and useful causes with zidoo developers, i.e. free upgradable kodi, system based sound and video addressing solutions and not by-app-solutions (3rd party players that aren't working because they don't understand the hardware).
    I already wondered if I made a good choice with this rather exotic x6, marketed with features I will never use (smooth 4k video) but which cannot decode by itself an ancient ac3 stream from a video file..
    anyway, no need to get upset on me for giving my 2c. if you find my comments disturbing just let me know and I will avoid arguing with you again, even if I think I have good reasons... cheers!

    I give up this specific discussion, I'm not disturbed by X6 LED and have nothing useful to say.

    i agree with you both: there are rather bigger issues that need to be solved from zidoo first!
    but from lower prio ones, this is just an issue from my side :)
    and thank you anyway for giving the input! who knows at some point zidoo will have time to have a closer look at this. and they would get here good hints.
    ..this is why i will keep asking once in the month if there are any updates. :)
