IoT

Building IoT devices isn’t just about getting them to work – it’s about making sure they keep working, securely and reliably, no matter where they are or what they’re connected to.

If your product needs to collect data, talk to the cloud, and operate smoothly in all sorts of conditions, the software behind it has to be solid. Scalable, maintainable, and secure – from day one.

That’s where we come in. At GoodByte, we handle the embedded software side of things, so you don’t have to worry about the low-level details. You stay focused on the product – while we make sure it runs like it should.

What have we done for the IoT industry?

Before we stepped in:

  • Issues with BLE functionality on the client’s current hardware platform.

Our task was to migrate to the Nordic nRF5340 chip, which natively supports the features that were previously achieved using several different integrated circuits in the first prototype version.

  • Insufficient device performance halfway through development.
  • Lack of experience with LTE-M and its services.

What the client got:

  • Ported the existing software to new hardware; fixed critical system bugs
  • PoC – launched VoLTE service for the LTE-M module using eSIM in Poland.
  • Implemented key features for the given prototype version: BLE, audio codec, SensorHub, GPS.

Result:

Functional and stable prototype that met technical expectations and enabled further development.

I rate my collaboration with GoodByte 9/10. This rating is based on three main reasons. First, the developers demonstrate exceptional competence in their field. Their deep technical knowledge and programming skills are undeniable.

Second, the developers’ inquisitiveness is commendable. They are ready to engage in solving complex topics and challenges. Their research-driven approach enables effective problem identification and solution development.

Third, the transparency and reliability of their work reporting. Receiving regular updates and progress reports on the projects is crucial. This allowed me to always stay in control of the workflow.

At the beginning of 2023, we started an NCBiR (R&D) project in which we lacked embedded software expertise. We chose GoodByte after a quick recruitment process of companies recommended to us. They stood out thanks to their experience in the technologies we needed and their concrete collaboration proposal.

With the small team from GoodByte, we smoothly navigated through the subsequent stages of the project together. They clearly distinguished themselves by their commitment to solving both the technical and business challenges related to our project.

We plan to continue our cooperation with GoodByte in the next project, which will require the development of electronics and software.

Wearable for patient tracking

Before we stepped in:

  • Nine months before certification and mass production, the firmware was still unstable and incomplete. Internal team changes caused critical knowledge gaps and delayed development.
  • The battery calibration process depended on a hardcoded configuration set during manufacturing. Once production started, there was no way to update it remotely — only a full device recall.
  • The client faced high costs, scalability issues, and potential delays or penalties related to post-launch updates.

What the client got:

  • A dedicated team of four engineers who accelerated development and helped push the firmware to a stable MVP, ready for production.
  • Reverse-engineered the undocumented calibration process and implemented a custom firmware module for in-field battery calibration updates — no need to physically access devices.
  • Stabilized critical modules including OTA updates and database communication.
  • Containerized development environment and CI-integrated release process for fast, consistent delivery.

Result:

Remote battery calibration unlocked. Client avoided costly recalls and launch delays — and gained full control over firmware updates, both now and in the future.

GoodByte is a small, cohesive team that has been working with us since mid-2022. We are jointly implementing a large embedded project for an external client. They provided us with experienced developers who quickly got up to speed with the project. They are open to collaboration and helpful, especially as deadlines approach.
