    Hello, I have a problem with my S brick, it wont turn on. I opened the shell of it to see what was wrong but couldn't find anything except the would led flash for a quarter of a second when I attach the extention wire from the battery box to the brick but the led wasn't bright, I could only just see it. Please help!

    Dear Connor, 

    Regarding the LED flashing, it isn't mean that the sbrick would be wrong. :)

    Would you be so kind as to send us an e-mail at info@sbrick.com with the details of the issue. 

    Please mention the device you use, and if it possible please create us a short video about the exact things you tried. 

    Thank you! 

    Best wishes,
    Balint
    SBrick Team

    The new firmware can be uploaded by using the "OTA" function of the mobile applications.

    Note that currently it's impossible to read the SBrick's firmware version (only with generic BLE tools), or the version of the firmware that is being uploaded, so the OTA function is there at all times, even after a successful update. (We keep improving the application, and since the we're behind schedule, we want the most important features to be out ASAP, even if they not quite complete. This is such a function, and it will be improved vastly in the near future.)

    The LED can only glow green, it doesn't even have a PWM connected to it, so the intensity can't be controlled (althoug it does "look" like a fifth channel from the software, and one can blink it by "going forward" or "backward", and can be lit continuously by "staying still").

    This same LED flashes rapidly while an OTA is taking place, or the user flash is being deleted at boot time. (Only on firmwares >4.1).

    Same here: no led blink on first startup (or not detected) very short blink after a few seconds on subsequent startups. 

    A slightly longer blink would be enough as far as I am concerned, but turning it on is fine too. Is the LED single colour or does it appear to be a different colour due to the different intensity? If it is capable of emitting different colours you could use those to idicate state and ID the SBrick. Else you could decide to use a lower intensity for "on" and full intensiy for ID.

    How can I install the new firmware you mention?

    Thanks for the update! I already understood indeed that it's not intended to stay on, but in combination with the current version of the app not connecting to the Sbrick, it wasn't immediately clear if it was a software or hardware issue. The new firmware sounds like an improvement on that part, as it provides more intuitive feedback to the user.

    That LED is the identification LED and was not inteded to be a "power LED".

    In the early firmware versions, the LED only turned on when it was instructed to do so. It's function is to serve as an identification method in case of using multiple SBricks. You can quickly check which BSrick you are connected to by pressing a test button.

    However we've received many reports from customers thinking their SBrick is faulty because of the dark LED. Therefore our newest firmware will kep the LED on, and it will blink when the ID function is on.

    Just a quick flash (almost nothing really) is fine. To be honest, that flash is just a technical glitch, it shouldn't really happen. If you're LED is dark, your SBrick is probably works OK. Try to find it with the application.

    If the app can't find it, try Nordic's nRF master controller application. You should see a sevice called "SBrick" (or "SmartBrick" in case of very early prototype hardware).

    Where can I find the test util?

    Mine also gave a tiny blink on powerup, but the the LED won't come on under testing unless I open the casing. By the way, the plastic you see is redirecting the light from a surface-mounted LED, so there are no wires to break.

    If it still flashes via power, should be okay.

     

    Do the ports work via the test util?

     

    When my LED doesn't work via test util, neither do the ports and that seems to be a bluetooth pairing issue. If it is paired properly, both work fine.

     

    It seems brick pairing is "delicate" at the moment.

    Having similar issues, except mine isn't working. LED indeed gives a very short and hard to notice blink when attached to power, but never switches on constantly. Also, it was sticking out of the brick a bit, about 2 mm, but when I touched it, it slid into the casing, hoping it didn't break a wire or so.

    Noticed the incredibly slight flicker on startup. Yeah, I think you could do with increasing the time that is on for and maybe also the brightness.

    That said, the first time I tested the brick, it still didn't light up. Does now.

    OK, thanks for the report! So this is not a hardware problem. The fix for the led comes in the next SBrick firmware release.

    This is the odd thing. When I connected the power. Nothing. Not a sausage.

    When I tried the test thing, nothing.

     

    Came, wrote this. Phone went to idle. Came back to it, tried it again and LED works.

     

    Not sure if it is tempramental or was just in a tiz initially. Will keep an eye on it.

    Is it blink for a short time when you power on the SBrick?

    I am guessing the dot on the front is the LED.

    When I connect the power, it doesn't come on. When I switch the LED on and off via the SBrick test on the APP, it doesn't work.

     

    Controlling a motor does work though, so there is power etc.

     

    Anyone else having this issue?
