Scope: This ATMP (Multi-Point) Command Set document along with BlueRadios
to enable developers and integrators an opportunity to evaluate wireless networks using Bluetooth technology.
The goal is to make the transition to Bluetooth wireless networks as seamless and easy as possible for our clients.
This document will explain how to establish Bluetooth communications between two or more BlueRadios for both
data and voice applications in a point-to-point network (i.e., cable replacement, slave/master communications
only).
“Our technology delivers a dynamic experience that comes out of the wireless delivery mechanism and
the freedom to connect others.”
This document describes the hardware interface of BlueRadios Intelligent Serial Module. The Module is
designed to be built into an embedded device and to provide a simple and low cost Bluetooth API interface.
The module is designed to integrate with a wide range of applications and platforms with a simple electrical
and software interface using AT commands.
Background: The BlueRadios evaluation board is designed to accommodate the Companies Class1
or Class2 Bluetooth radio modem serial modules with 2.4GHz RF ceramic chip antenna (pictured
right). The BlueRadios SMT modules are Bluetooth ver2.0 compliant and use the BC04 Base band
processor from CSR. The evaluation board enables a stable platform environment to test serial RS-
232 cable replacement and audio communications over Bluetooth RF links before going directly to an
embedded printed circuit board design and layout.
AT Commands: This document describes the protocol used to control and configure BlueRadios Bluetooth
Serial Modules. The protocol is similar to the industry standard Hayes AT protocol used in telephone modems due
to the fact that both types of devices are connection oriented. Appropriate AT commands have been provided to
make the module perform the two core actions of a Bluetooth device, which is make/break connections and
Inquiry. Additional AT commands are also provided to perform ancillary functions.
The CSR (Cambridge Silicon Radio) BC04 base band processors are used in the BlueRadios modules. Memory
resources are limited therefore it is NOT proposed that there be full implementation of the AT protocol similar to
an AT modem. But in fact, the protocol is similar enough so the existing source code written for modems can be
used with very little modifications with this serial module. Also because of the same resource limitations the Multi-
Point modules support connections up to 4 remote devices.
Just like telephone modems, the serial module powers up into an unconnected state and will respond to inquiry
and connection requests. Then, just like controlling a modem, the host or client can issue AT commands which
map to various Bluetooth activities. The command set is extensive enough to allow a host to make connections
which are authenticated and encrypted or not.
commanded, and controlled through simple ASCII strings through the hardware serial UART or over a remote
Bluetooth RF connection.
HEX vs. Decimal – When writing or entering integer AT Command string values these are typically in Decimal
format, when reading values from memory they are returned in HEX (hexadecimal).

1. All commands have the following format: “command”<cr>. Where “cr” represents carriage return 0x0D
2. Valid commands respond with a “<cr,lf>OK<cr,lf> or “<cr,lf>ERROR<cr,lf>. Where “lf” represents linefeed
3. All response data after the command response have the following format <cr,lf>data<cr,lf>.
