Wappsto:bit Setup

Getting Started with your SLX Wappsto:bit


Get the Wappsto App

Download the Wappsto Native App from Apple's AppStore or Google Play.

To log in, you can simply use your Google, Facebook or Apple accounts. If you'd prefer, you can also create a separate Wappsto account and sign-in (note you'll receive an activation email).

Connect your Wappsto:bit

First, connect your Wappsto:bit to power via the micro USB port located in the bottom right corner of your device. The LED will light up.

In the Wappsto Native App, press the plus button in the upper right-hand corner to add your device.

2a) If you're connecting the Wappsto:bit Basic, choose 'Add and configure Wi-Fi' and follow the on-screen instructions.

2b) If you're connecting the Wappsto:bit NB-IoT or NB-IoT+, choose 'Add via QR code' and follow the on-screen instructions, where you'll use your device's camera to scan the QR code*.

NB: step 2B will work if you have been provided a Telenor NB-IoT SIM card by Seluxit. Otherwise, see ''configuring your APN' at the bottom of the page. Don't worry, it's super easy.

Configure data collection in MakeCode

Use the Wappsto extension in Microsoft MakeCode to decide what data to capture and how often.

First you'll need to create a new project in MakeCode, clicking the big purple plus icon on the left-hand side of the page. Then install the Wappsto extension, which you'll find under the settings cogwheel.

Now, you program your micro:bit just as you normally would, using the Wappsto extension to send data. Take a look at this example for the basics.

When your program is ready, download it onto your micro:bit and put your micro:bit in your Wappsto:bit.

Take care not to sample too much data as it can incur a cost to you depending on your setup. We'll soon publish guidelines to help you avoid sending too much data.


Interact with your data

In the Wappsto Native App, you can see and control your data immediately.

Then, go to wappsto.com and access your Wappsto account. Use Chrome or Firefox, as wappsto.com has not been optimized for Microsoft Edge.

There, you'll find the Dashboard where you can add a new dashboard using the Wappsto:bit template.

NB: the Dashboard will soon be an integrated experience in Wappsto.com, but currently, you'll find it as a pre-installed 'wapp' that you can access simply by clicking on the icon.

Further information

  • Reset button

    Note that you can reset your Wappsto:bit using the reset button. Press and hold the reset button. The LED indicator will flash until it turns solid, and then the color changes to red. When the color is solid red, you can release the reset button. This will bring the Wappsto:bit back to its unboxed state.

    This feature is useful for changing ownership of the Wappsto:bit, especially in classroom settings, where several students may use a single Wappsto:bit in the course of a day.

    Keep in mind that data transferred during use remains in one’s personal Wappsto account. Note also that you are not removing the code from the micro:bit itself.

  • Power

    The Wappsto:bit requires a 5V power supply. You can use a wall socket, your computer, or a power bank. It is not possible to power the Wappsto:bit through the micro:bit.

  • Cloud Pricing

    Each product in our shop includes a list price for the hardware. Included in the price is data traffic and data storage on our cloud, up to a value of DKK 50 / €6,50 per month.

    This is plenty of data for more users, but if you require more, additional data storage and data traffic is priced based on the schema you’ll find at seluxit.com/pricing.

    Note that with the NB-IoT version, you’ll additionally need to acquire an NB-IoT SIM card and corresponding subscription. See the 'NB-IoT Considerations' section below.



  • How do I switch between Wi-Fi and NB-IoT?

    First, make sure you have a Wappsto:bit NB-IoT or NB-IoT+ product. Then you just switch the position of the jumper on the pin headers as shown in the images below.

  • How come I’m not getting GPS info?

    Take a look at the example code in the ressources area above, and keep in mind that only the NB-IoT+ product is equipped with GPS.

  • Why doesn't my sensor work

    Keep in mind that some external sensors are 5V sensors, but the voltage provided form the Wappsto:bit is 3.3V, so you’ll need an alternative setup to power 5V sensors.

  • Problems downloading code to micro:bit?

    If your micro:bit is inserted in your Wappsto:bit and both are powered, you might experience some difficulties. This can arise because of a so-called 'common ground' issue. Just take your micro:bit out of the Wappsto:bit and try again.

NB-IoT Considerations

  • What is NB-IoT anyway?

    NB-IoT is a cellular data for the Internet of Things. It's a 5G standard for IoT that helps optimize battery life and reach for IoT devices.

  • Supported Geography

    Wappsto:bit NB-IoT and NB-IoT+ are currently optimized for Europe, frequency bands B3 (1800) and B20 (800). Versions supporting different geographies will be developed. Are you outside Europe? Write to sales@seluxit.com to hear more.

  • Getting an NB-IoT SIM card

    Currently, you'll need to acquire a NB-IoT SIM card and accompanying subscription yourself from a telecommunications company in your area.

    Note that we're currently developing chip-SIM products, where the NB-IoT SIM will be built in, though locked to a single provider.

    Also, keep in mind that NB-IoT is currently supported in Europe. See the topic 'Supported Geography' above.

  • Configuring your APN

    If you're using your own NB-IoT SIM card (that is to say, not a Telenor SIM card provided by Seluxit), you'll need to configure your APN. Fortunately, this is easy. Just ask your provider what the APN is, and put that in the 'configure cellular APN' in MakeCode once in your 'on start' code block, as shown below.

    configure apn
  • NB-IoT Pricing

    Note that the subscription for NB-IoT is NOT included in the subscription pricing for Seluxit's IoT cloud, where DKK 50 / €6,50 is included for free.

    NB-IoT pricing is a separate consideration, cf. 'getting an NB-IoT SIM card' above.

    In the coming chip-SIM products, we plan to price the cellular subscription into our product.
