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 the world's first test solution for this new test mode,
making its debut at embedded world 2025.
MUNICH and ROCKVILLE, Md. , March 5,
2025 /PRNewswire/
-- Rohde & Schwarz and Ceva today 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 closely 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.
OTA-Testing for small and highly integrated
Bluetooth® devices
Until now, wearables and other
small and highly integrated Bluetooth® devices required
testing using the Direct Test Mode which involves a control cable
between the test instrument and the device under test (DUT).
Especially encapsulated DUTs make it difficult or even impossible
to integrate a connection for this control cable. Hence,
sending test control messages over the air without any cabling
between tester and DUT as specified in the UTP mode will simplify
the test setup immensely.
Radio controlled testing powered by Ceva
The
Ceva-Waves Bluetooth® Low Energy platform
provides a fast, low-risk path for integrating low power and robust
Bluetooth® Low Energy connectivity into a
system on a chip (SoC). The suite of optimized, integrated hardware
IP and software has been deployed and
Bluetooth® SIG qualified in many customer
chips. It has been shipped in billions of devices across various
markets including consumer, automotive, industrial, mobile and
smart home. Ceva-Waves Bluetooth® Low Energy
IP stood out as the ideal choice for Rohde & Schwarz to
integrate it in their OTA UTP Tester, due to its maturity and
robustness, combined with the technical support Ceva provides its
customers throughout the development process.
Tal Shalev, vice president and
general manager of the wireless IoT business unit at Ceva,
commented: "Rohde & Schwarz has long been a leader in
Bluetooth® testing, and their highly respected
R&S CMW radio communication tester platform continues to
set industry standards. The introduction of
Bluetooth® OTA UTP Test Mode is a crucial
advancement for testing next-generation consumer
Bluetooth® products, and we congratulate them on
this timely innovation, powered by Ceva-Waves
Bluetooth® technology."
Unified Bluetooth® testing over-the-air
The
Bluetooth® UTP Mode on the R&S CMW radio
communication tester platform offers a simple and precise signaling
test solution, perfectly suited for Bluetooth® Low
Energy radio tests in development, pre-conformance and production
testing. All Bluetooth® Low Energy and
Bluetooth® Classic Radio measurements are unified and
can be performed with a single test setup over the air in a
signaling connection. Comprehensive test automation and the highly
accurate implementation of the Bluetooth® test cases are
crucial to ensure compliance to the Bluetooth®
specifications.
Christoph Pointner, Senior Vice
President for Mobile Radio Testers at
Rohde & Schwarz, says: "Thanks to our close
partnership with Ceva and their highly-proven
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 well-established R&S CMW platform.
This highly anticipated solution will enable vendors and
manufacturers of wireless chipsets, modules, and devices to test
their products over-the-air with greater ease. In addition, they
will be able to perform the testing for all Bluetooth®
radios with the same test setup."
Both partners are actively involved in defining the
specifications within the Bluetooth® Core Specification
Working Group, ensuring that the test solution will be in line
with the specifications of the upcoming Bluetooth®
release. In addition, the solution is compatible with the already
ratified Bluetooth® releases up to release 6.0
Channel Sounding, supporting the existing Direct Test Mode (DTM)
with the conducted control connection.
Rohde & Schwarz will showcase this ready-to-market
test solution from March 11 to 13,
2025 at Embedded World in Nuremberg in hall 4 at booth
4-218.

software.
