Rohde & Schwarz and Ceva Announce Over-the-Air Bluetooth Test Solution

The next Bluetooth release is expected to be ratified soon. One important new feature is the Unified Test Protocol (UTP) Test Mode for Bluetooth Low Energy, that will complement existing test methods. The UTP Test Mode will additionally enable over-the-air (OTA) controlled device testing, which will simplify measurements of small and highly integrated devices enormously, since no direct wired connection to the tester is needed. Rohde & Schwarz and Ceva, in close cooperation, have developed a solution for this new test mode.

And being a Swedish brand, Polestar 2 also features Spotify Group Sessions Beta directly in its built-in Spotify app.
