  • Page 5: Chapter 1 - Introduction

    Chapter 1 – Introduction Overview This document describes the protocol used to control and configure the Multi-Tech Systems, Inc. SocketWireless Bluetooth device. 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 are make/break connections and inquiry.
