    In my opinion it seems that the KS project has been undertaken with great knowledge of both HW and SW, but the team has underestimated the SW development trickeries when it comes to supporting things on a wide variaty of devices. Also, as soon as the HW was delivered, everyone´s expectations were raised: "the HW looks great, why isn't the SW of the same quality?" It´s really frustrating to have the device in posession for a while now without being able to use it at all.

    I would like to see a page where users could check and perhaps also update their experiences per device, in order to get a clear overview of what works and what doesn't.

    Hello,

     

    Is the SBrick protected against the application of reverse polarity?

    The HW seems solid, but only time and hundreds of Wh passed through it will tell ...  and this is the best news (together with option to run in with 3rd party apps - like nRF control panel)

    The compatibility with broad scope of different devices is always a challenge - we have a product at work that 'should' run on most current devices and its a never ending fight. Even more if the Sbrick uses a feature (BLE) that is quite young in terms of adaptation. 

    But the SW is a mess or better say the disparity compared to the 'equality' as presented in the KS campaign. There is no priority announced for any of the platforms, even the need for 4.3+ android is not mentioned. So saying "iOS is a little better but at best is still beta" is a bitter understatement if one group can play with the working profiles (see that all the youtube videos returned for sbrick use only iOS profiles), another is left with mostly useless alpha test profiles (even missing the pledged ones) and last one (WM) cannot do anything now.  

    Although I would not use such strong words Steve, I understand the reason.

    More so, if the SBrick team shown thorugh constant updates on the HW production, how even delays can be communicated and explained...

    I mean, how hard would it be to hardcode to 'market' the profiles that iOS guys have since v3.0 from November to the Android app ?

    Steve, I'm also a customer. A paying customer who also paid to be a beta tester. And a satisfied one.

    I feel your pains, honestly. But SBrick is a crowdfunding product. Vengit went from almost zero to a full physical product in 4 months. It's a good product, there are already several people using it, you can find many videos here at social.sbrick.com or at youtube. And yes, the software component is very poor but it is alpha (Android at least, I thing iOS is a little better but at best is still beta). They are also releasing the protocol so it's just a matter of time until 3rd party apps show up (I've been using python and linux, raspberry pi, LEGO Mindstorms EV3 to control it almost from the first day I received my beta SBrick).

    Could it be better? Yes, it could. And it will be. Just give it a few weeks more and give it some help and support.

    Instead of a Lego® I.R.-Receiver, a SBrick does function on the old Lego® 9V system!

    Thanks for the help and the good idea! 

    About forum usability on android:

    I can use it on stock browser, after blank page loaded, I click on "ask for desktop site" in the browser's menu. Then it reloads the page and after I can read/write. But it still very slow because of the f*** pile of JavaScript. :)

    Here a example of my old 9V batterybox connected to my Lego I.R.-Receiver with a homemade adapter.

    Tomorrow I will test it with my SBrick.

    I looked at the extension cable with multimeter, and it links +9V and 0V of the old style 9V battery box to C1 and C2. Is it possible to use cable like this to give power to the sbrick or I have to cut it and solder the right wires to the battery connector?

     Maybe if I shortcut e.g. C1 to +9V and C2 to 0V I can resolve the problem without knife and save the cable. :)

    OK, my SBrick is inside my nativity scene so it have to wait a few days til I can use it but I can confir it uses 0 and 9V pins from the light grey plug.

    I have used the SBrick with one of these PP3-to-PF adapters (http://custombattery.blogspot.pt/):

    I checked with my multimeter, the PP3 + and - are connected to 0 and 9V pins of the PF plug.

    The SBrick is powered by the top part of the PF connectors (either dark grey or light grey), it fits over it. I cannot confirm right now but Iam pretty sure it uses 0 and 9V, not C1 and C2. If you want to save the cable, you can plug the SBrick over the light grey plug and then over again a 9V (cutted) cable or an 9V electric plate and use some aligators.

    Hi.... I just got my sbrick today. But
    the green led light on the sbrick is only flashing sometimes when I turn it on . Then my phone(samsung galaxy s3) can connect to the sbrick a few seconds and loses the connection again...
    My LEGO cable is new and there is new battery's in the batterybox.. Is there anything wrong with my sbrick or is it only bugs and so.... kind regards....

    Yes, it is ok with the your firmware version, so the SBrick boots up. I'll ask the developers how can I debug it remotely. We tested with iPod Touch and not faced this problem.

    Now it suddenly works. Will continue to monitor. I tried with horizon express and had the same issue as Jakob (https://social.sbrick.com/forums/topic/51/port-test-100-turn-off).

    Strange. Please try restart your iPod Touch, and try again. I think it will be a problem in the iOS bluetooth stack. Please tell the results.

    no change. I also updated to 8.1.2 and restarted.

    is that normal that the green LED only flashes up once after turning power on?

     

    update: ok, now I have a connection. Strange. But seem to work now.

    Hi all

    How can I connect to SBrick?

    I just received 2 SBrick but I can't connect to any. I used an iPod Touch with Bluetooth 4.0 and iOS 8.1.

     

    When I connect SBrick to a power source and turn on the power I can see flashing a green LED once and shortly on the SBrick.

    In the SBrick app under manage bricks i can see three times "SBrick" (but I have only two). If I try "Identify led" or port tester, nothing happens (connecting to bricks > lost connection).

    What can I do?

    Regards, Jerome

    Oh, I see.

    The BlueGiga company manufactures a number of devices. Their main profile are electronic modules that can be used by electronic developers.

    They indeed have a dongle called "BLED112" which plugs into the USB port. This dongle can "speak" BLE, and looks like and USD serial port device from within the computer.

    This however won't solve any problem by itself, since it's a development tool, and it's not really for end users.

    ( ( ( Curious fact: we use BlueGiga's BLE113 module inside SBrick ;) ) ) )

    Currently WeDo needs a cumbersome wire connection to the PC. I thought I read somewhere Bluegiga plugs into the USB port for wireless connection? I don't know much about SBrick yet but perhaps if SBrick already can connect wirelessly via Bluetooth such stuff not necessary?

    Apologies if I sound ignorant.

    Hello Peter,

    no, SBrick doesn't support WeDo, and the current hardware is not suitable for this task.

    Why did you mention BlueGiga? I don't undarstand your last question, can you rephrase it? Thank you!
