2.4. Switching on for the first time
The Bluetooth RS232 Mini Adapter is equipped with a high-performance rechargeable battery, so an external
power source is not required. This makes the adapter particularly suitable in mobile applications.
We recommend charging the batter before using the device for the first time (see section 2.3).
A Bluetooth connection between two devices is always in the form of a Master-Slave connection, i.e. one device
always initiates the connection. The new Bluetooth RS232 Mini Adapter can be operated in both Master and in
Slave mode, i.e. the Bluetooth RS232 Mini Adapter can also establish a connection with another Bluetooth device
and is not restricted to waiting for a connection request from an external piece of equipment.
The only condition is that the partner device supports the Bluetooth serial port profile (SPP).
When the Bluetooth* RS232 Mini Adapter is switched on for the first time, it is in Slave mode. You can then select
between two operating modes: Normal mode and Configuration mode.
In Normal mode a data connection is set up to the Bluetooth* Adapter; the Configuration mode is used to
configure the settings for the Bluetooth* Adapter either via the Bluetooth connection or the serial interface.
The standard configuration of the LinTech Bluetooth* RS232 Mini Adapter is as follows:
Baud rate
: 115200 Bit/s
Stop bit
: 1
Parity :
None
Data bits
: 8
Bluetooth* PIN
: 1234
Before the configuration of the Bluetooth connection can be changed, the device must be switched to
configuration mode and a connection must exist to a Bluetooth device (for further information please see the
corresponding section of the manual).
If you want to create a connection from another Bluetooth device to the RS232 Mini Adapter without changing the
configuration, continue as outlined in the following sections.
