Project Scope

For Comarch, the project started with building a testing platform as the basis for the further development and verification process for the client. Simultaneously, we have been running hardware tests in search of possible improvements. After presenting the results to WSA, we assisted with fixing issues. The next step was to develop the device low level drivers in C++ and implement Bluetooth module support for the audio stream services. We have also provided the test framework to ensure the usability and to support the further implementation of planned features.

Experienced Team

Comarch started the project with half of the required engineers. The team was extended during the first months of the project. All in all, Comarch has provided WSA with a team of 11 specialists – nine software developers, a Product Owner and a Scrum Master. Our team works internally on its tasks. However, it is not separated, as the cooperation with WSA is very close and continuous, including in the field of current consulting and software integration. Our team was introduced into the processes of the WSA organization, so we can truly say we are partners at work.

Benefits of using Bluetooth in hearing aids

  • Easy connectivity across all Bluetooth devices – capability to connect with a device such as smartphone, notebook, etc. and using hearing aids as wireless earbuds
  • Remote control of hearing aids internal settings such as volume using dedicated secure mobile app
  • Monitoring the state of the battery inside hearing aids

We selected Comarch as our partner in developing the new generation of hearing aid solutions because of their experience and great qualifications in Bluetooth connectivity, as well as hardware and embedded systems expertise. This decision proved to be the right one. The framework development was always on track, and the deliveries reached their expected functionality. What’s more, our partners at Comarch has always been very proactive in contributing their efforts to drive hearing aids technology forward. I recommend Comarch as a services provider and a trusted business partner.
