      When afre we getting it. Haven't received the Shields until now!

    4. Michael Kroll on January 18, 2013

      @Tyler I think we already discussed that by email.
      @John The BLE Stack should support up to 4 connections at the same time. But your application has to deal with that since the BLE-Shield is no longer advertising, while connected. I'll test that tonight and add your question to the FAQ I need to setup on as well tonight.
      @Rafael We are expecting the BLE112 modules to arrive at latest on monday. The production of the second final batch will start then and will be shipped before chinese new year.

      @all Another batch is going to be produced afterwards for all interested "non Kickstarters".

      Any news about the shipping?

    6. Josh Deese on January 16, 2013

      Does the shield support connections to multiple devices simultaneously (e.g. connected to iPhone 5 and iPad at the same time)?

    7. Tyler Darlington on January 8, 2013

      Is there any way to get a tracking number for the BLE Shield?

      Hi Ian, I believe he said 'mourning' not 'moaning' but all the same we agree... we know the issues and have put them out there for backers but we do make some assumptions that is not readily apparent to you. For that, we truly apologize. The issue is that the manufacturer that is handling the production is not doing a good job of sourcing the BLE112 modules for us. They should have had them ready to go, as was our understanding, as soon as we provided the money but that wasn't the case. As it stands, they have received 84 modules so far (of the 300) that have been built and shipped to backers in a first backed, first shipped order. Again, we apologize for the delay. At this point there is one and only one factor delaying the completion of this project... the sourcing of the BLE112 modules. As these trickle into the manufacturer, they will be built and shipped. It's extremely frustrating for us and I know for our backers but the simple truth is that we have our hands tied as we are at the mercy of the manufacturer and their ability to source these parts. Not what anyone wants to hear of course but hope this helps a little? Cheers!

      Hi Michael

      Sorry if you think we're moaning but, in my mind, an update saying that you are still waiting is better than not hearing anything. It's a matter of perception you, on the front line, face the delays first hand and know what's going on. Us, further down the line, don't know what's happening.


    10. Michael Kroll on December 19, 2012

      Dear Backers,
      I will post another update with some pictures of the assembled shields by the end of this week Seeedstudio promised to send some photos before sunday. There are still problems sourcing the BLE112 modules, but one third of the Shields are already in production. The other two third will of the BLE112 modules are expected arround the 21st of January. So sorry again for the long delay, but it seems that the lead times are not as promised by Blugiga at all.

      Maybe it is one of the worst projects some of you might have backed, but do you want to get updates every week, stating that there is still problems while sourcing the modules? We have not expected this enormous delay in the lead times, but it seems that the BLE market is currently exploding and the demand for chipsets and modules overwhelmed many people working with this new technology.

      The first shields will be shipped according to the rule first backed, first served. Se second half will follow late january/first half of February. I will make the next update this weekend and the next one when the first third is shipped. Afterwards I will update you guys once the next delivery of BLE112 modules has arrived and then a last one once the last boards are shipped.

      Sorry, but I was hoping that the production and delivery will take only 4-6 weeks as initially calculated, but this has changed.

      For all who are mourning, try a technology kickstarter yourself. It's different to realise it if you are not a company but doing everything in your sparetime :-) The delay is currently not caused because I'm not able to deal with the technology. The Shield is working for months now and there are Universities and Research Facilities already working with the shield, giving good feedback and like to work with it. You will be able to prove it very soon!

      Thanks for your understanding,

    11. Ian Lewis on December 19, 2012

      So, any news on shipping? I haven't noticed any updates in a while? If the parts were delivered on time you should have something ready to go by now?

      this is one of the worst projects I've backed for updates..


    12. Craig Dunn
      on December 12, 2012

      So, per the last update, did the BLE112 chips arrive on December 6th so assembly could commence?


    13. Rowdy Robot 2-time creator on December 5, 2012

      Hi Ben, we posted an update on 11/28 explaining the delay and that we still hope to have them shipping out before Christmas. Cheers!

      Yet almost every single project on Kickstarter fails to come close to delivery, there should be a penalty for false advertising.

    15. Tyler Darlington on November 24, 2012

      Hey Michael, I was wondering if there was any updates on the shipping of the BLE shield?

    16. Michael Kroll on November 2, 2012

      Hello Michel,
      yes you're right the shipping deadline will be november. In my initial estimation, I was thinking to get the money earlier from Kickstarter/Amazon. The Survey was sent out yesterday, since the production of the shields for the backers was already started on wednesday. I will prepare another updated once I get photos from the production lines. I'm very curious as well, to see hundreds on shields in a Pick-And-Place step, soldered and ready to be shipped to you.

      The last prototype before the mass production was verified without big issues. So the production was started as expected. Thanks for your patience. You will get the shields soon :-)

      Missed the October shipping deadline, but at least now we had the survey.

    18. Jonas Arvidsson on October 22, 2012

      Hello Michael!

      I'm just wondering if there are any updates regarding the delivery of the sheild? =)

    19. Michael Kroll on October 8, 2012

      Hi Michele,
      if you are interested in contributing to the Shield's firmware, please register

      The sources of the Shields firmware as well as
      the sample iOS app we be published on github soon.

      Moreover I'm already working and planning some
      new hardwares :-)


    20. Michele Fadda on October 8, 2012

      Hello Michael, I'm one of the pledgers.
      I'm glad you had the idea of kickstarting your shield and look forward to receiving my unit.

      I'm a firmware developer and an iOS developer.
      I also bought a mini-dk and plan experimenting a lot with Bluetooth low energy.
      I would gladly follow your invitation and help/collaborate exchange ideas.

    21. Michael Kroll on October 4, 2012

      Hello Yariv,
      I will post the final schematics and board files over the weekend to the blog ( an the forum ( as well. The final firmware files will follow asap, since I'm now preparing the final testplan for the manufacturer while waiting for the final backers list and plege amount from kickstarter.

      The complete board itself is not FCC approved. The bluetooth module itself is FCC, CE, etc.

      Once we got the money from Kickstarter/Amazon, production will start and the parts will be directly shipped to all of you.

      Thanks again for the great interest in the shield,

    22. YarivB on September 28, 2012

      Hi Michael, looking forward to receiving my Shield, looks awesome !

      Two questions:
      1. When will we be able to download schematics/etc ?
      2. Do you need FCC approval for such devices ?

      Great, thank you :)

    24. Michael Kroll on September 20, 2012

      Hello Jose,
      thank you for the nice comment on the BLE-Shield. You are right I wanted the v1.0.0 Shield be open so everyone can modify it and share changes and new features with the community.

      No sorry for the v1.0.0 BLE Shield there are not additional GPIO pins available on the Arduino Shield headers.
      I have some ideas for the next iteration of the Shield, maybe a version 2.0.0, but I want to invite others to participate in the design of the next board as well. I will open up a forum board soon where firmware and hardware demands can be discussed as well as new designs.

      I hope to see you in the forum soon :-)


    25. Jose M on September 20, 2012

      @olivier Yes that is correct and even better than that, you can also write and flash your own firmware onto the BlueGiga Bluetooth module (you need a "TI Debugger" programmer gadget though, but that's available from all good electronics distributors)

      All the (easy to understand) BGScript source code for this shield's firmware is available on Michael's website so you can change it to your heart's content. You can hardly get more open than this!

      I also received the RedBearLab BLE shield from Seeedstudio to play around with, but it's really no match for the functionality this one offers.

      ps: a question for Michael, are there any extra GPIO pins from the BlueGiga module available in the headers?

      olivier on September 20, 2012

      Am I right thinking that this shield (the one I'm backing) works with the default Arduino IDE and only requires an open source library?

    27. Michael Kroll on September 14, 2012

      @Ken You asked me about the advantages/disadvantages compared to the BLE Shield available at Well I received the BLE Shield they sent me for testing today. I downloaded the Arduino IDE they are providing, and compiled the BLEFirmata Sketch. The Sketch consumes ~20.5kB of the available 28.6kB for Sketches on the Arduino Leonardo. Compared to this size, my BLE Shield RFID sample, where I use the Adafruit RFID Shield to transfer Tag UIDs takes 8.3 kB of the available Sketch size. The Temperature Demo, where I was reading the temperature and humidity value from a SHT21 or SHT15 over I2C takes 8.4kB of the available Sketch. Moreover it is very easy to write a sophisticated Temperature/Humidity app for the iPhone (what I will to tomorrow to proove it) to read the temperature and humidity data and show it.

      I never played arround with firmata before, but the iPhone App to control the nordic chip based BLE Shield, offers you to control and read the digital and analog pins. What about I2C devices, or UART Communication or SPI?

      I just asked these questions on their support forum, awaiting an answer soon.

      I think which one to choose depends on what you want to do with it.

      Then you'd want the WTFPL (

    29. Michael Kroll on September 13, 2012

      Ok, it'll be some kind of "Do whatever you want" license.

    30. Andreas
      on September 12, 2012

      MIT would be nice, because it's short and simple.

    31. Michael Kroll on September 12, 2012

      What licence would you suggest? Apache 2.0?

    32. Andreas
      on September 12, 2012

      Under what license will the iOS sample code be released?

    33. Michael Kroll on September 12, 2012

      Hi Ken,
      I think they both have advantages/disadvantages against each other. I have not yet tested the BLE Shield from RedBearLabs. I received one today they shipped me. I'm in good contact with the developers and we already started to exchange experiences. There is not fight against each other comparable to the Apple/Samsung one ;-)

      At this time I can only say that all resources of my shield, including the Schematic, Boarddesign and even the Firmware of the BLE112 module is available open source and the community is free to change and improve. This has already started with the firmware of version 0.9.2 and 0.9.3 so there will be an optimized firmware available for v1.0.0


    34. Ken Hargreaves
      on September 12, 2012

      Are there advantages to the BLE112 you use over the Nordic nRF8001 used in this BLE Shield?…

    35. Michael Kroll on September 11, 2012

      Hi Tyler,
      I'm sorry but no. Version 1.0.0 of the Shield
      will use the BLE112 with chip antenna.
      Maybe a connector for an external antenna can
      be used in a future design, but this is not part of this


    36. Tyler Darlington on September 11, 2012

      Hey Michael,

      May seem like a simple question but, will the BLE Shield be able to use an external antenna for connectivity assuming it is mounted in a aluminum chassis?


    37. Michael Kroll on September 9, 2012

      Hello Martin,
      it is not compatible. Both projects are using BLE Technology but both are peripherals. The BLE Shield could maybe reprogrammed to act as central in order to discover tods, but the firmware is not supporting it. Since the Firmware is open sourced and there is a programming header on the BLE-Shield you can do this on your own :-) You don't have to pay for shipping. It is already included in the pledge amount.


    38. Martin Schmidinger on September 9, 2012

      Am I right that this would be compatible with the tōd smart beacon project? So I could set up a Arduino with BLE Shield and Ethernet Shield and when the tōd is in range the Arduino could send a command via http to some other service?
      Second question, do I have to pay for shipping to Austria?
