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, a copy of which is available from Stollmann.

3 Deployment
3.1 Startup
To deploy the BlueEva+C11/G2, connect it as follows.
Figure: BlueEva+C11/G2 as delivered
The USB connection may be used as an alternative to the 5 VDC mains adapter.
The USB port is exclusively used to supply the BlueEva+C11/G2 with power. It does
not serve any additional functions.
You may connect the RS232 connector to the COM port of a PC. This lets you use a
terminal emulation program such as HyperTerminal to perform the configuration and
control the Bluetooth connection.

3.2 Configuration
If the BlueEva+C11/G2 is correctly connected to the COM port of the PC, a terminal
emulation program can be used to read and modify the configuration settings.
For a more detailed description of the AT commands used for this purpose, please
consult our AT Command Reference.
With default settings, the BlueEva+C11/G2 works at 115,200 bps, using the 8N1
data format (8 data bits, no parity, 1 stop bit). Please configure your terminal
emulation program accordingly.
Figure: COM port configuration with HyperTerminal
Once you have successfully configured the emulation program, issuing the “AT”
command without parameters should prompt the BlueEva+C11/G2 to return OK.
Now you can readout information about the type of the connected device using the
“ATI” command.
Next you should issue the “ATI99” command to determine the firmware version
installed.

Finally you should use the “AT**BOAD” command to determine the Bluetooth
address of the BlueEva+C11/G2 and note it. The Bluetooth address is unique,
letting you identify the correct device for each Bluetooth address.

3.3 Getting Started
3.3.1 Establishing a Bluetooth Connection Between two BlueEva+C11/G2
Using the Serial Port Profile (SPP)
First of all, determine the Bluetooth addresses of the two BlueEva+C11/G2. To do
so, connect each of the BlueEva+C11/G2 to the COM port of the PC and readout
the Bluetooth address using the “AT**BOAD” command as described in Chapter 3.2
Configuration.
You can either use a single PC with 2 COM ports or two separate PCs with one
COM ports each.
Now you can establish a connection from one BlueEva+C11/G2 to another by
issuing the “ATD<Bluetooth Address>” command.
Figure: Establishing a Bluetooth connection between two BlueEva+C11/G2
If the connection was established successfully, the originating BlueEva+C11/G2 will
issue the message CONNECT. You can now send data transparently between the
two BlueEva+C11/G2.
To terminate the Bluetooth connection, click “Disconnect” in the terminal emulation
program. If the Bluetooth connection is disconnected successfully the remote
BlueEva+C11/G2 will issue the message NO CARRIER.

3.3.2 Automatically Establishing a Bluetooth Connection Between Two
BlueEva+C11/G2 Using “Auto Connect”
It is possible to configure the BlueEva+C11/G2 to automatically establish a
Bluetooth connection to a second (remote) device without having to take control
manually.
This requires that you store the Bluetooth address of the remote device on the
BlueEva+C11/G2.
The following figures describe the steps needed to run the BlueEva+C11/G2 in
“Auto Connect” mode.
The BlueEva+C11/G2 can be configured to different auto connect modes. In this
example we read out the Bluetooth address of BlueEva+C11/G2 (A) and set it to
command set 12 “incoming calls only”.
Figure: Configuration of the remote BlueEva+C11/G2 (A) with Auto Connect
Then BlueEva+C11/G2 (B) is configured to command set 8 „connect on DTR“.

Figure: Configuration of the master BlueEva+C11/G2 (B) with Auto Connect
Now the BlueEva+C11/G2 (B) will attempt to automatically establish a Bluetooth
connection to the remote device, which in our example is the second
BlueEva+C11/G2 (A).
If the connection was established successfully, the LED 2 indicates the successful
Bluetooth connection (ON: Bluetooth connection is established). You can now send
data transparently between the two BlueEva+C11/G2.

To terminate the Auto Connect mode, you will have to turn off the BlueEva+C11/G2
(B) device, configure your terminal emulation to 9,600 bps.
Figure: COM port configuration with HyperTerminal
Turn on the BlueEva+C11/G2 again and wait for the
“+++ Press <CR>, <CR>, <ESC>, <ESC> to enter BlueRS+ configurator“ message.

Now you can enter the configuration mode with “<CR> <CR> <ESC> <ESC>” within
2 seconds and load the default values of the module using the “defa 1” and “save”
command.
For the BlueEva+C11/G2 to retain the Auto Connect setting correctly, the unit will
have to be cycled off and back on.
For more information about “auto connect”, please consult our AT Command
Reference.

4.5 Serial Interface
The BlueEva+C11/G2 provides a serial interface which is used to connect a
communication device for transmitting data or a PC for controlling the
BlueEva+C11/G2. The serial interface corresponds to the V.24/RS-232 standard
and supports the following features:
• Transmission speed: 300 – 921.600 bps (asynchronous)
• Character representation: 7/8 bit, no/even/odd/mark/space parity, 1 or 2 stop bits
• Hardware flow control with RTS/CTS
The BlueEva+C11/G2 can be used in DTE or DCE mode. This requires a special
setting in the firmware. The selection of the appropriate D-SUB socket is made by
jumper J2.20.
