Bluetooth^® testing

From mobile phones and vehicle hands-free systems to speakers, conventional headphones and headsets, Bluetooth^® wireless technology can be found in nearly all communication and audio devices – albeit profiles, codecs, signal processing methods and more may differ.

But the aim is always the same: to give end customers the best-possible user experience thanks to high-quality audio playback and lossless communication between devices. Manufacturers have to ensure this by conducting a range of acoustic and electrical tests.

The combination of a reference interface with test procedures for a range of Bluetooth^® compatible audio and communication devices provides manufacturers and test laboratories with a unique test environment.

Our solutions enable lab-based testers to:

• Establish a direction connection with the reference interface
• Ensure compatibility and conformity among devices for all standard profiles and codecs (e.g. HFP, A2DP, Qualcomm^® aptX™, mSBC)
• Optimize signal processing (audio quality, level, echo compensation, noise suppression, etc.) where required
• Ensure transparent and error-free transmission for gateway applications
• Check the correct implementation of different connection types and associated protocols (e.g. AT commands such as “NREC Off”)
• Test complex scenarios
