1 Objective
This DesignGuide documents how BlueRS+I can be integrated into customer
systems. It addresses developers of hardware and software environments for
BlueRS+I. For detailed information about technical data refer to the manual.
Since BlueRS+I is under permanent further development, some information might
alter. The following documentation is therefore meant to provide an overview.
Stollmann expressly declares that this DesignGuide is no basis for a layout.
This documentation is a recommendation to the best of our knowledge. Stollmann
does not assume any liability for the information in this documentation nor for any
damages related to or caused by the use of this Design Guide.
2 Product Description
BlueRS+I connects an asynchronous serial interface with TTL level with the
Bluetooth interface.
2.1 Product Versions
2.1.1 Power Supply
The BlueRS+I is supplied through the double row connector. It can be configured for
5V (default) and 3,3V supply.
2.2 Operation Modes
BlueRS+I runs in three modes:
2.2.1 AT-Mode
The Bluetooth connection is controlled by AT commands of the end device. You
have full control over configuration and initiation of the serial link.
2.2.2 Autoconnect
For some legacy applications or cable replacement, it may be difficult to actively
establish a serial connection before sending the data over the serial link. If you do
not want to program the host device, the BlueRS+I automatically establishes the
serial connection to a previously configured Bluetooth address.
2.2.3 Autoconnect DTR
With the activation of the DTR line, the BlueRS+I Bluetooth connection is set up
automatically. No adaptation of the integrating device is required since the BlueRS+I
is meant to be a transparent serial cable replacement.
