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.

Mesh Networks

A mesh is a network of nodes, where messages are propagated through the net to the dedicated receiver.
A mesh refers to a multiple connection between devices or nodes: the nodes/devices connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data.
They differ from conventional network topologies, which are based on the hierarchical connection between a small subset of nodes.

WE meet @ Digital Days 2021: Wirepas Mesh: From Concept to Prototyping

What are the main parameters and characteristics of a mesh network?
  • Speed
  • Current consumption
  • Throughput
  • Maximum number of nodes
  • Installation effort
  • Robustness

Mesh Technologies

Flooding Mesh

Each node just forwards the message. We differentiate between synchronous and asynchronous flooding mesh.


  • Easy to use
  • No network organization (installation, change)
  • Size does not matter


  • Increased traffic
  • Duty cycle problems
Routing Mesh

The network master or each node knows the path.


  • Shortest/Cheapest path


  • Extra network organization traffic
  • Size limitations (master handled)
  • Less robust on network changes
  • Master has to know when adding/removing a node
Asynchronus Mesh

Messages can be transmitted at any time


  • Fast
  • No installation effort
  • No size limitations


  • Energy consuming (~100% RX)
  • High probability for radio packet collision

The WE-ProWare Asynchronous Flooding Mesh is integrated into following products

Synchronus Mesh

All nodes are synchronized and transmit/receive at determined time slots.


  • Energy efficient (sleeping mostly)
  • Time and frequency hopping possible


  • Synchronization effort (master needed)
  • Size limitation
  • Low throughput/High latency
Which Mesh solutions can WE offer you today? - WE-ProWare

Asynchronous flooding mesh capability is integrated into our proprietary firmware for the modules Thyone-I, Tarvos-III, Thebe-II, Thelesto-III & Themisto-I.

Which Mesh solutions can WE offer you today? - Wirepas

Asynchronous and synchronous routing mesh capability is integrated into our Wirepas module Thetis-I.

Wirepas Mesh

What is Wirepas?

Wirepas is an international company with headquarters in Tampere, Finland.

Wirepas is specialized in IoT topics and offers the Wirepas Mesh stack (firmware only) and support to high volume customers. Würth Elektronik is in cooperation with Wirepas to integrate the Wirepas mesh stack into radio chips as well as offering service to our customers to develop Wirepas mesh radio modules based on the existing Nordic Semiconductor nRF platform.

Würth Elektronik is licensed to develop, support and sell standard and custom Wirepas mesh radio modules.

What is Wirepas Mesh?

Wirepas Mesh is a connectivity protocol for radio modules, optimized for large scale and energy efficient wireless mesh networks in the frequency 2.4 GHz. This innovative technology can be used to create large IoT networks, for example using battery-powered sensors, in which each node also functions as a router.

On a single MCU solution, the application runs on the device itself. On a dual MCU solution, the application runs on a host microcontroller.

What are the strengths of Wirepas Mesh protocol?

Traditional mesh networks suffer in large scale from complex networking tables, congestion and bandwidth issues. Wirepas overcomes these issues by removing network‘s infrastructures and decentralizing network‘s intelligence on the nodes. All networking decisions are done locally by the nodes. Every node:

  • scans automatically the neighborhood and choose the best path to the sink
  • adapts transmit power to neighbor proximity
  • can act as sink, routing or non-routing node
  • can work in low power or low latency mode
  • chooses the best frequency to use locally
  • has a high configurability, interference-tolerance, ultra-low energy consumption: Wirepas mesh software is ideal for large scale and battery-operated networks.
How can I start building up my Wirepas prototype network?

The Thetis-I Evaluation-Kit

For Thetis-I we offer a specific Evaluation kit, which consists of:

  • 1 Mini Evaluation Board
  • 1 USB Stick
  • 3 battery driven sensor nodes

Their specific functions are showed in the picture below.

In case you need a larger test network, you can simply extend your starter kit by purchasing additional pieces of any of the three hardware components ( mini evaluation board, USB stick, sensor node ).

Together with our proprietary software tool Wirepas Commander, you can setup and test your Wirepas network in few easy step.
