Project overview

What is Bluetooth® LE Audio?

Bluetooth® LE Audio is the planned evolution to Bluetooth® Classic which has been enabling the industry with wireless audio for decades. LE Audio utilizes the low power and low resource radio of Bluetooth® LE, significantly improves the sound quality with its updated standardized audio codec and delivers new broadcast capabilities enabling a trifecta of improvements and enablement of new use cases that truly is game-changing.

New Features in Bluetooth®

Bluetooth® LE Audio was first introduced i n version 5.2 of the Bluetooth® specification. Now, new features such as Multi-Stream Audio Auracast™ and Broadcast Audio with Personal and Location-based Audio Sharing – not to mention a revolutionizing LC3 codec – allow consumer electronics manufacturers to develop attractive products for customers. All of those new features replace existing solutions with much better versions, and add more exciting use case opportunities to improve everyday life. The latest Bluetooth® 5.4 specification also introduces a new capability – Periodic Advertising with Responses (PAwR). That ultra-low power networking feature is expected to enable high-volume applications – including Electronic Shelf Labels (ESL) – for retail apps where thousands of connected end nodes are synchronized with infrastructure.

What is Packetcraft’s goal?

Packetcraft’s driving goal is to deliver leading-edge software stacks and solutions to help propel the market forward benefiting their semiconductor and product companies with advanced features, performance and differentiation. Packetcraft fulfills their objectives by investing in technology development as the specifications are being drafted, being early to market, and developing strategic initiatives with key customers and partners all while focusing on offering best-in-class performance and support.

Comarch’s contribution

Introduction to the project

Comarch, a software company intensively involved in the world of IoT and consumer electronics solutions, is always looking for innovative partners to cooperate with. So, starting a project with Packetcraft was a natural move for us – as we wanted to enhance Bluetooth® audio technology alongside the industry leader. After a short time, the Comarch engineers team was established and introduced to the tasks.

What challenges did Comarch address?

Together with Packetcraft’s engineers, we were working on optimization of the code to make sure that performance and space for new functions were there to use in the future. We implemented new profiles and services for clients’ product needs and were responsible for new test case implementations for the automation and qualification processes.

What did Comarch bring to the project?

During our collaboration, we were able to show our technical skills regarding embedded systems, code analysis, and BLE protocol. We got to know Packetcraft’s stack better, and expanded our practical knowledge of new BLE specs. Thanks to good planning and excellent communication on both sides, ramp-up time was efficient, and the project quickly gained momentum. All that with the help of our highly-motivated and skilled junior staff members, who turned out to be a great asset to this undertaking.

Comarch is a reliable partner. They deliver good quality embedded services with their technical skills. We were happy that they could help us build and improve our product. We put our trust in them, and it turned out to be a great decision. The team is very dedicated and transparent in their actions. The results of their work are definitely worthy of recommendation.”
