ROHDE & SCHWARZ AND CEVA PRESENT INDUSTRY’S FIRST TEST SOLUTION FOR BLUETOOTH OTA UTP
6 March, 2025
The next Bluetooth release is expected to be ratified soon. The UTP Test Mode will enable Over The Air controlled device testing, simplifying measurements of small and highly integrated devices.
Rohde & Schwarz and Ceva have unveiled the world’s first test solution supporting the upcoming Bluetooth OTA UTP Test Mode, enabling over-the-air (OTA) controlled device testing. The two companies will showcase their joint solution at Embedded World 2025 in Nuremberg.
Rohde & Schwarz and Ceva collaborated to develop this test solution powered by Ceva-Waves Bluetooth Low Energy IP. It runs on the R&S CMW radio communication tester platform from Rohde & Schwarz, with integrated Ceva-Waves Bluetooth Low Energy controller software licensed from Ceva.
Bluetooth Device OTA Testing
Until now, wearables and other small, highly integrated Bluetooth devices required testing using the Direct Test Mode, which involved a control cable between the test instrument and the device under test (DUT). For encapsulated DUTs, integrating a connection for the control cable was difficult or even impossible.
With the specification of UTP mode, test control messages can now be sent over the air without any cabling between the tester and DUT, significantly simplifying test setups.
The Ceva-Waves Bluetooth Low Energy platform has been deployed in billions of devices across various markets. The Bluetooth UTP Mode on the R&S CMW radio communication tester platform offers a simple and precise signaling test solution, ideal for Bluetooth Low Energy radio tests in development, pre-conformance, and production stages.
All Bluetooth Low Energy and Bluetooth Classic Radio measurements are unified and can be performed wirelessly in a signaling connection. Comprehensive test automation ensures compliance with Bluetooth specifications.
Industry Perspectives
Tal Shalev, VP and General Manager of the Wireless IoT Business Unit at Ceva, commented:
“The introduction of Bluetooth OTA UTP Test Mode is a crucial advancement for testing next-generation consumer Bluetooth.”
Christoph Pointner, Senior VP for Mobile Radio Testers at Rohde & Schwarz, stated:
“Thanks to our close partnership with Ceva and their Bluetooth Low Energy IP, we were able to implement the new Bluetooth UTP Test Mode in line with the specifications of the Bluetooth Core Specification Working Group on our platform.”
Both companies actively contribute to defining the specifications within the Bluetooth Core Specification Working Group. The solution is compatible with previously ratified Bluetooth releases up to Release 6.0 Channel Sounding and supports the existing Direct Test Mode (DTM) with a conducted control connection.
