Introduction
The Multi-Tech Systems, Inc. SocketWireless® with Bluetooth®-enabled technology allows developers to establish cellular
networks using a special set of AT commands. The SocketWireless with Bluetooth technology makes the cable-replacement
transition to cellular networks seamless and easy.
This chapter explains how to establish Bluetooth communication between two serial devices for data applications in a point-
to-point network. Bluetooth-enabled devices create communication-ready devices by integrating data functionality into a
single, universal socket design. This complete, ready-to-integrate device dramatically reduces development time and costs for
system designers.

Notes about Byte Gaps and Data Latency
Because of the way Bluetooth is designed and operates, random byte gaps of 5 ms to 20 ms are common. Packet size
will vary from transmission to transmission.
Although the serial band frequency operates up to 920K bps, effective data throughput in fast streaming mode is
approximately 200K bps. Effective data throughput in regular data mode is 60K bps. The reason for the slower speed
in regular mode is due to the AT parser, which looks at each character for ASCII valid command scripts in the regular
mode's data stream.
The SocketWireless RX has very limited buffering, so if you do not use hardware flow control and are transmitting
further distances, you will quickly overflow the 50 byte buffer because of RF retransmissions, etc.
When a Bluetooth connection is made, the SocketWireless device goes into regular data mode per the power-up
factory default settings. This enables the user to configure the SocketWireless settings remotely via a remote RF
Bluetooth connection. Basically, you can setup the SocketWireless device so no commands are required to be sent
from the embedded side of the device. This allows seamless interfacing with legacy systems without the need to
modify the host device
