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.
Thank you! :)
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. :)

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.
I'll come back you soon.

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.
[/blockquote]
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.
Or would we need to use Bluegiga?

I posted a new thread in the Support forum but perhaps that should have been posted here instead?

The Lego WeDo uses the Lego Power Function motor and a wired USB connection to the desktop loaded with Lego WeDo software or the MIT Scratch software. The WeDo hub need to be connected to the computer with a wire to the computer USB hub.
Will Sbrick work with Lego WeDo? Anyone working on this or anyone have any information on how this may be achieved?

Tested it at last, it works on Ubuntu:

I'll give more details later.

Argh! Forget it!
I can send ONE command, just that. So motor keeps spinning for a second, no response to BREAK or COAST.
Have to investigate more.

Can you test it please? Unfortunately I don't have any linux running BLE device with python right now (workgin on it ;) ).

Hi! The app will be released to the general public in November.
Beta testers can ask for access NOW. :)
The profile designer will be available as a web appication, it's much easiear to drag graphical elements around on the desktop. :) It will be available in December.

Hi Jorge,
Thanks for the reply. I would be happy enough to have it use the iPhone as a "forwarder" to the SBrick... There are a few gamepad style controllers available (Logitech for example). But I'm guessing the SBrick software on the phone would need to accomodate input from these controllers somehow. Is this a feature that is being considered? If not, it would be great to add to the list of "future features".
[/blockquote]
Hi Ian, we're considering this, it would be really cool. This won't be in the first app release though. Once we shipped the first few thousand of bricks, dealt with the first bug reports we can start working on the "feature queue". :)
[/blockquote]
Excellent news Tamas! Pleased to hear it's on the list. Is there any word on when the iOS app will be released so we can start designing profiles for our SBricks?
Yes, unfortunately BLE is not very well penetrated the open source libs and languages yet.
I'll take a look at PyBlueZ too, since IanHarvey's solution is using bluez too, it might be easier to write a patch to a well established library than poking around in a higly experimental one.
Thanks.
It would be great if you get/create something "universal" - Linux, Android, OSX, iOS and even Windows.
My trick (calling gatttool) only works in Linux, perhaps also in Android. And there is no such thing as initialization of the device, persistence of the session, etc... Its good for fast demos but on the long run it's uselless for non-geeks.
By the way... after just 4 or 5 days of these tricks, my wife and kids are enthusiastic with my beta SBrick, I guess Santa will have to bring some Power Function Motors :D
