RN-BT-SRL-UM-1.0

CONFIGURATION

The Bluetooth adapter operates in two modes: data mode (default) and command mode. While in data mode, the module

is essentially a data pipe. When the module receives data, it strips the Bluetooth headers and trailers and passes the user

data to the UART. When data is written to the UART, the module constructs the Bluetooth packet and sends it out over the

Bluetooth connection. Thus, the entire process of sending/receiving data to the host is transparent to the end

microprocessor. See Figure 2.

Figure 2. Data & Command Modes

The default configuration for the Bluetooth adapter is:

• Bluetooth slave mode

• Bluetooth pin code 1234

• Serial port 115,200 Kbps baud rate, 8 bits, no parity, 1 stop bit

• Serial port flow control disabled

• Low power mode off

You configure the adapter by putting it into command mode and sending ASCII commands over a serial port or the

Bluetooth link. Once you change the configuration parameters, they persist until changed or you perform a factory reset.

There are two ways to configure the Bluetooth module:

• Local configuration using your computer’s serial port

• Via Bluetooth

You need a terminal emulator to complete the setup.

NOTE: Roving Networks suggests using either the TeraTerm (Windows OS) or CoolTerm (Mac OS-X) terminal emulator

program.
