Embedded software development from Lauf/Erlangen, Germany

Embedded Development – we start where others stop.

Embedded software runs inside the device itself – and that is exactly where we work. K-Type is your team for IoT connectivity (BLE/WiFi/Mesh), medical device firmware, and Edge AI, including hands-on Auracast/LE Audio experience. Deep specialist knowledge instead of a generalist approach, for manufacturers whose in-house team has hit its limits.

01 · IoT & Connectivity

BLE, WiFi, Mesh & Auracast

Devices that connect reliably – even in real-world field conditions.

02 · Medical Technology

Firmware for regulated products

Safety-critical embedded software, documented for audits.

03 · Edge AI

Computer vision & LLMs, embedded

AI capabilities directly on the device – no cloud dependency.

Proven in the field

20+BLE model lines shipped for WSAudiology since 2017
400+parking areas running IoT we built for BetterPark
1 dayinstead of a month to a working BLE prototype at a client – with our easyBLE toolkit for UI–BLE integration
10×cheaper BLE audio verification with our in-house test tool

01 · IoT & Connectivity

IoT devices built to hold up in the field – not just in the lab

For manufacturers who want to add a wireless feature to their device but don't have in-house radio expertise.

❌ Typical problem

Your team has embedded experience but no radio expertise – range and connection stability work in the lab, not at the customer's site
Unclear which stack (BLE, BLE Mesh, WiFi) and which chip platform fits the application
Companion app and firmware are built by separate teams that develop past each other

✅ Our approach

Firmware on Zephyr RTOS, Nordic nRF and Espressif platforms, precisely tailored to the use case and power budget
iOS/Android companion apps from a single team (.NET MAUI), so firmware and app teams don't develop past each other
Field tests with our own analysis tools instead of pure simulation, before the product ships to the customer

Reference customers in this area: Wanzl, Winterhalter, BetterPark, nexobility – industrial and IoT manufacturers who implemented wireless features without an in-house radio team.

Highlight · Auracast

Hands-on Auracast experience, before the market demands it

Auracast/LE Audio is new – most development teams only know the spec on paper. We've been building and testing Auracast products since the first silicon.

❌ Typical problem

Auracast/LE Audio is new to the market – few developers have hands-on implementation experience
Unclear how to reliably implement broadcast audio, multiple receiver roles, and channel switching
Testing without the right equipment is barely possible – reference hardware for all four Auracast roles is scarce

✅ Our approach

Our own test dongle BASSist emulates all four Auracast/LE Audio roles with a bidirectional USB audio pipeline – for fast prototyping and solid testing
Our own Auracast reference products built to production-ready quality (headset, receiver, microphone kit) – see examples on the right

K-Fan+ Auracast headset – K-Type's own reference product

K-Shouter+ Auracast microphone kit – K-Type's own reference product

Our own Auracast reference designs from the K-Fan/K-Shouter series – built to make concepts tangible for customers before their own product exists.

Market timing: starting in 2026, the Bluetooth SIG expects significantly broader Auracast hardware coverage across smartphones and the first hearing aid manufacturers. Those who start now are ahead of mass adoption.

02 · Medical Technology

Firmware that holds up in your company's QM system

For medical device manufacturers who want to add BLE or software features without tying up their own team in IEC 62304 documentation work.

❌ Typical problem

In-house developers are strong in embedded C, but IEC 62304 documentation eats up more time than the actual code
Risk management and evidence are bolted on afterward instead of being designed in from the start
External vendors without medical technology experience deliver code that gets kicked back at audit

✅ Our approach

We develop as a supplier inside our customers' IEC 62304 quality management system – documentation and evidence are produced alongside the code, not after it
Peer code reviews and automated unit/integration tests as standard, not an add-on
Experience from real medical technology projects, including for a hearing aid manufacturer – we know the requirements and processes from practice

Reference: WSAudiology / Sivantos – embedded software development as a supplier for an internationally active, certified hearing aid manufacturer. K-Type itself is not IEC 62304 certified – we work within our customers' QM system.

03 · Edge AI

AI capabilities directly on the device instead of the cloud

For manufacturers who want to use computer vision or voice features directly on the device – without cloud dependency, latency, or privacy risk.

❌ Typical problem

Cloud-based AI services mean latency, ongoing costs, and privacy concerns – unsuitable for many embedded applications
Few teams master both embedded systems and AI models (computer vision, LLMs)
Models need to run on limited hardware – pure data science know-how isn't enough for that

✅ Our approach

Experience with classic computer vision frameworks (OpenCV) and integrating LLMs into embedded systems
Reference project: automated license plate recognition on embedded hardware – from image capture to evaluation directly on the device
We're deliberately expanding our Edge AI capabilities – the current focus for the future is offline simultaneous translation with no cloud connection at all

Reference project: automated license plate recognition on embedded hardware. Edge AI is an area we're deliberately expanding – the next milestone is offline simultaneous translation with no cloud connection.

I worked on a project with Martin. To paraphrase a well-known saying: nobody gets fired for choosing K-Type. It's that simple.

Really pleasant collaboration! The team works efficiently, transparently, and with strong technical expertise. No unnecessary detours — just targeted solutions, and at a fair price. Highly recommended!

About Us

Four people, one focus – no anonymous ticket handling

Since 2012, K-Type has helped mid-sized companies bring IoT, medical technology, and Edge AI features to production – including hands-on Auracast/LE Audio experience. The team has deliberately focused on these areas – instead of "software for everything." Direct contact with the people actually working on your project: short paths, open communication, trust, precision, and quality come first.
