Wireless Connectivity SDK

The aim of the Wireless Connectivity Software Development Kit (SDK) is to minimize the effort required on customer side to enable his host MCU to communicate with Würth Elektronik eiSos radio modules. It contains the implementation of all available commands in pure C-code. In order to integrate any Würth Elektronik eiSos wireless module, the user has to simply port the corresponding C-code to his host processor. This significantly reduces the time needed for developing the software interface to the radio module.

Thyone-I Updater

This tool provides the possibility to update the firmware of a Thyone radio module via the UART interface. It requires an exclusive connection of UART RX, TX RTS and CTS to a com port on the Windows PC. Firmware images for Thyone and Thyone Bootloader in the most recent version come included in the package and can be installed with a couple mouse clicks on the Thyone module connected to the PC. For more information regarding firmware updates on Thyone refer to the product user manual.

Due to current export legal restrictions, we are required to control the provision of software. To download the software, please contact our technical support or your local sales representative directly. Thank you for your understanding.

Stacking boards ideal for prototyping

WE FeatherWings

Würth Elektronik eiSos presents, a range of FeatherWing development boards that are open source and fully compatible with the Feather form factor. Through these development boards WE brings a range of wireless connectivity modules, sensors and power modules to the Feather ecosystem.

Adafruit Feather is a complete line of development boards from Adafruit and other developers that are both standalone and stackable. They're able to be powered by LiPo batteries for on-the-go use or by their micro-USB plugs for stationary projects.

Feathers are flexible, portable, and as light as their namesake.FeatherWings are stacking boards and add functionality and room for prototyping. At its core, the Adafruit Feather is a complete ecosystem of products - and the best way to get your project flying.

Supercharge your prototyping for easy and fast solution testing. Start by checking our quick start section.

Application Examples

Example 1: Built a Proprietary Network
Example 2: Connect with Wi-Fi
Example 3: Send data with Wi-Fi

Example 1: Built a Proprietary Network

  • Select a microprocessor of your choice from the Adafruit Feather ecosystem
  • Use the Sensor FeatherWing for measuring condition parameters like temperature, air pressure, humidity and acceleration
  • Send data with the Thyone-I FeatherWing on 2.4 GHz proprietary radio
  • Thyone-I USB radio stick or another Thyone-I FeatherWing can receive the data and you get access to all information
  • Even various tags could be connected wirelessly
  • We support you with libraries and examples available on Github for some microcontrollers

Send data with the Calypso Wi-Fi FeatherWing on 2.4 GHz Wi-Fi

  • Select a microprocessor of your choice from the Adafruit Feather ecosystem
  • Use the Sensor FeatherWing for measuring condition parameters like temperature, air pressure, humidity and acceleration
  • Send data with the Calypso Wi-Fi FeatherWing on 2.4 GHz Wi-Fi
  • Receive data on smart devices or server structures

Another simple application example is described here with the combination of an Adafruit Feather M0 Express with our Sensor FeatherWing and Calypso Wi-Fi FeatherWing.

A typical IoT application consists of sensing the environment through sensors, collecting the sensor data and forwarding it to a cloud. The cloud platform then provides options for further processing and visualization of the data. In this example, the data is read from the sensors of the Sensor FeatherWing and forwarded to a cloud platform via the Calypso Wi-Fi FeatherWing.

Currently, the data can be sent to one of the following cloud platforms:

  • Microsoft Azure
  • Amazon AWS

Sample code and further documentation can be found on our Sensor2CloudConnectivity Github page.

4 sensors to measure environmental data:

  • Temperature
  • Humidity
  • Acceleration
  • Absolute Pressure

An Adafruit Feather M0 acts as managing director.

The Calypso Wi-Fi FeatherWing collects the sensor data and passes it on to any cloud.
