BLEBee v2.0.0 prototype hardware and firmware finished. Works great !

Hello everyone,

I was a little quiet lately. I was not sleeping but working on a few hardware designs and another iOS BLE application.

After I created new versions of the BLE-Shield, the BLEBee is the another hardware that needs an update. The BLEBee v2.0.0 is now designed to use the BLE113-256k module which will enable OTA firmware updates without additional SPI flash. Moreover the power consumption will be slightly lower. Hot plate soldering the BLE113 works like a charm, so expect more designs in the future using the BLE113 or the BLE121LR 🙂

Due to the fact that the XBee form factor defines the size of the module, the outline has not been changed. See the following images comparing the v1.0.0 vs the v2.0.0 BLEBee:


The back of the new BLEBee is of course showing the new Micro-Labs logo:


The main differences in the hardware design currently is, that I removed the four digital pins I was using to control the Seeedstudio 4 channel relay shield. Since this shield is discontinued, I removed this functionality as well. The second worth mentioning changes is the change of the RX/TX characteristics to one Data characteristic.

This Data characteristic is comparable to the one used in Bluegiga’s Cable Replacement code sample. Using this new Characteristic it is easier in BLExplr to test communication without need to switch screens. RX and TX can be handled in on screen on one characteristic

And the most important thing might be the OTA firmware updated that is now possible. On my forum there were a few people asking about the possibility to update the firmware and that it is somewhat difficult to achieve using the additional TagConnect adapter which is necessary to achieve the update.

What is currently missing in the initial working prototype is the working CTS signal which will be one missing thing that I will add now. Since there is some additional space on the PCB due to the smaller form factor of the BLE113 module there could be some solder pins be added to attach the CC-Debugger for advanced software developers. This would allow to connect the CC Debugger using a custom adapter. Please let my know in this forum thread about better access to connect the CC-Debugger:

Expect more details on the characteristics once the design is finished. If you like more features to be added please contact me on twitter, this blog or the forum.

Thanks for reading and your interest in my products,

    Hey there,

    Any hot plate you would recommend to us? Or the one you are using for this?

      Hi Tyler

      I’m using a 20 bucks one from a home electronics shop here in Zurich.
      Nothing special. I measured the temperature of the plate when it’s on the highest setting which gives me 250 deg. Celsius and
      I just solder for about 20 – 30 secs.

      Works out fine.

    Any idea when v2.0.0 will be available to the market?

    seeedstudio doesn’t longer carry the v1.0.0

      the BLEBee v2.0.0 is in its final testing. I hope to get a quote soon so they will be hopefully available sometime after chinese new year.

        Hi Michael. Will the BLE-Shield v3.0 be ready for sale at Seeed on that date as well? I’m very interested. And, is there a way I still could buy version 2.0? Thanks!…

          Hello Jose

          a soldered pre production prototype of the BLE-Shield v3.0.0 is expected to be finished in two weeks.
          I will then kick off the production.
          A very small amount of BLE-Shield v2.0.0 is available directly through me. I will solder them by hand on request for the same price as it was offered at Seeed.
          Shipping may more expensive since I’m shipping them from Switzerland.

          It will be even cheaper when I don’t solder the Arduino headers.

            Can your BLE-Shield v2.0.0 be used as a central client to receive data from a peripheral wearable heart rate sensor?
            If so, I am very interested in purchasing one.

          • Michael Kroll March 27, 2015 at 13:13 #


            Yes you can do this but you need to reflash the firmware and use BGLib provided by Jeff Rowberg. This is not an Out of the box feature and it is not possible with the original firmware I’m providing.


          • Tim March 30, 2015 at 19:40 #

            Do I reflash to factory or something custom? Is reflashing the firmware something you can step me through?

    By the way, do you have plans for developing a Shield or breakout for the BT111? I’m developing a product in which I’d need a Smart Ready BT. So, if you have a plan to release a Shield or breakout for it, I’d be very interested as well. If not, do you know somebody’s else breakout for the BT111 that you would recommend? Thank you a lot :-)! Regards.

      Hi Jose

      I don’t have plans for such a shield or breakout board yet.

    When will v2 be available for sale? I need to get one.

    • Michael Kroll March 27, 2015 at 13:11 #

      I’m still preparing the test rig and creating the testplan. Once this is done I’ll kickoff production.
      Will let you know soon about the progress and when to expect them to be in stock at Seeed.

    I was wondering if the SCl/SDA also are included in the pinout of BLEBee v2.0.0 Rev.A.?

    • Michael Kroll March 1, 2016 at 10:00 #

      Hi Jenny,
      no sorry the SCL/SDA pins are not available on the BLEBee v2.0.0
      Maybe an improvement for v3.0?
