Multi-Tech Systems, Inc. Quick Start Guide
Using AT Commands to Set Parameters
Parameters, such as the Bluetooth Name, Service Name, Device Class,
and Serial Port settings can be viewed and configured. This can be done
locally through the serial port UART or from a remote Bluetooth RF link.
To configure the Bluetooth adapter, it must be in command mode; issue
the +++ command to switch to command mode. While in command
mode, the adapter will accept ASCII bytes as commands.
The communications settings should match the settings used when the
Bluetooth adapter connects. For example, the defaults are:
9600bps, 8 bits, no parity, 1 stop bit, hardware flow control enabled.
