Note
This device was developed for the purpose of communication in an office environment. It is
intended solely for our industrial clients for physical integration into their own technical products
after careful examination by experienced technical personnel for its suitability for the intended
purpose. The device was not developed for or intended for use in any specific customer
application. The firmware of the device may have to be adapted to the specific intended modalities
of use or even replaced by other firmware in order to ensure flawless function in the respective
areas of application. Performance data (range, power requirements, etc.) may depend on the
operating environment, the area of application, the configuration, and method of control, as well as
on other conditions of use; these may deviate from the technical specifications, the Design Guide
specifications, or other product documentation. The actual performance characteristics can be
determined only by measurements subsequent to integration. Variations in the performance data of
mass-produced devices may occur due to individual differences between such devices. Device
samples were tested in a reference environment for compliance with the legal requirements
applicable to the reference environment. No representation is made regarding the compliance with
legal, regulatory, or other requirements in other environments. No representation can be made and
no warranty can be assumed regarding the suitability of the device for a specific purpose as
defined by our customers. Stollmann reserves the right to make changes to the hardware or
firmware or to the specifications without prior notice or to replace the device with a successor
model. Of course, any changes to the hardware or firmware of any devices for which we have
entered into a supply agreement with our customers will be made only if, and only to the extent
that, such changes can reasonably be expected to be acceptable to our customers. No general
commitment will be made regarding periods of availability; these must be subject to individual
agreement. All agreements are subject to our Terms and Conditions for Deliveries and Payments,

1.2 Applications
The BlueMod+SR can be used in different applications. Regardless if the application requires high
throughput or low energy consumption, BlueMod+SR offers the best of both worlds. Some typical
applications are described in this chapter.
Supported profiles are:
BR/EDR:
SPP
LE:
Terminal IO
any GATT based LE-profile
Support for any additional profile is possible on request.
1.2.1 General Cable Replacement
The Serial Port Profile (SPP) on the BlueMod+SR can be used for UART data transfer. The
connection is transparent for the user application and supports Secure Simple Pairing, making the
pairing process easy and the connection secure.
1.2.2 Industry
Typical Bluetooth application include scanner, printer as well as automation controls. In the
automation application area Bluetooth is mainly used for transport of I/O signals. Bluetooth low
energy can be used to monitor and control motors, actuators, values and entire processes.
1.2.3 Automotive
Modules are mainly used in aftermarket application like personal navigation devices, head units or
audio applications. These applications are typically Bluetooth BR/EDR only.
1.2.4 Healthcare and Medical
The healthcare and medical market offers a lot of possible application for Bluetooth BR/EDR and
Bluetooth Low Energy. Usage of Bluetooth is aimed mainly at devices that are used for monitoring
vital data. Typical devices are blood glucose meter, blood pressure cuffs and pulse ox meters.
Bluetooth BR/EDR and low energy were chosen by the Continua Health Alliance as transports for
interoperable end to end communication.

1.2.5 Sports and Fitness
In the sports and fitness segment Bluetooth is used in devices for positioning as well as monitoring
vital data. Typical devices in this market are heart rate monitors, body temperature thermometers,
pedometers, cadence meters, altimeter, positioning / GPS tracking and watches displaying
information from sensors.
1.2.6 Entertainment
Bluetooth technology is already used in a wide variety of devices in the entertainment sector,
namely set-top boxes / gaming consoles. Bluetooth low energy is expected to further increase the
use of Bluetooth technology in devices like TV / DVD / STB / Media Player, remote controls,
gaming controller, wireless mouse/keyboard.
