Wireless Remote Development (WRD)

To meet the challenges of wireless IoT development, SSV has developed a new toolbox called "Wireless Remote Development (WRD)". The WRD toolbox contains methods and function blocks for the three task areas of debugging, end-to-end (E2E) testing and monitoring. The WRD services are the central component of the new SSV development.

They are operated as an integration level in a cloud or on-premises between the embedded systems and IT software components of an IoT application. These services can be used to continuously supply a DevOps team with telemetry data for the entire application.

Furthermore, the WRD services enable specially secured remote debugging access to all software functions, i.e. from the individual embedded system of a wireless IoT sensor to the smartphone app of the user of the IoT application.

The scope of this horizontal system integration provides IoT developers with a multifunctional E2E test platform as a modular application for the first time.

R&D Manager Jürgen Fitschen from SSV explains: "From a cybersecurity perspective, wireless remote debugging of an IoT endpoint in particular is a highly sensitive matter. That's why we have developed a pairing method and a highly secure end-to-end tunnel that uses a central WRD Rendezvous Service as a transparent infrastructure component.

However, even this communication service cannot view or manipulate the encrypted session data. The key required to pair the two endpoints is negotiated directly between the developer PC screen and the remote debugger device by means of optical data transmission.

A similar procedure is also used in banking, for example, to generate secure TANs using flicker code. A secure remote debug connection can only be released by a new pairing or via a blacklist."
