BluetoothTM protocol testing plug-in for Rohde & Schwarz
Testing the BluetoothTM protocol will become easier for
users of the Rohde & Schwarz PTW60 protocol tester thanks to a
plugin developed by Da Vinci Communications.
The plugin integrates two separate test system components when TTCN is
the test notation being used (the PTW60 user can also program the test
specifications in C).
The combined solution will save users cost, time and risk of error.
Overview of the Leonardo Synergy Solution
Rohde & Schwarz is a leading international communications
company that released the first Bluetooth Protocol Test System to the
With separate system components, testing was split into a TTCN
editing/debugging task on one machine and an execution task on
another. The error-tracking process could be made more efficient: Test
suite errors, which are reported by the PTW60 compilation process,
that transforms TTCN code to C code, were being written down and dealt
with separately on a machine holding the Leonardo Editor Pro, creating
a risk of inaccuracy and causing the process to be less efficient than
it needed to be.
The testing tools
- 1. PTW60 protocol tester
- The PTW60 has been developed to help manufacturers of Bluetooth
equipment during the development process as well as supporting the
TTCN test suites defined by the Bluetooth SIG. The PTW60 performs
protocol tests of protocol layers and profiles. It automatically
converts the TTCN test specifications into executable code.
2. Leonardo Editor Pro
- The Leonardo Editor Pro is a sophisticated tool that creates and
edits TTCN specifications. It combines a user-friendly interface with
powerful features and uniform handling across many different
The Pro version's interface is able to develop and run
plugins. This feature extends the functionality of the editor because
it makes it possible to access other tools from the editor's
Da Vinci's PTW60 Plugin combines the PTW60 and the Leonardo Editor
Pro into one integrated development environment.
The solution simplifies the editing and compilation of TTCN test
suites and enables the transparent handling of all transactions
between the Leonardo Editor Pro and the PTW60.
A "Build Manager" provides a tree view of the build
directory structure on the PTW60 tester. This enables users to view
PTW60 tester directories from the Leonardo Editor Pro, delete unwanted
versions or builds, view meta-information, and load test suite files
from the local machine or the PTW60.
- All TTCN development can be handled by the single interface of
the Leonardo Editor Pro.
- Rohde & Schwarz users can now remotely control the TTCN
compiler and checker on the PTW60 tester from within Leonardo Editor
- TTCN related errors reported by the PTW60's compiler are
intelligently fed back into the Leonardo Editor Pro's debugging
mode. Test specifications can then be edited and corrected immediately
from the same interface.
- Leonardo Editor Pro can be used for all TTCN testing and
development, including managing the PTW60 protocol tester's source
code and executable files, managing the building and compiling of
applications using the plugin's Build Manager.
