Bluetooth Raw Serial Module Technical Specification

Document#: 6410-00195 A Revision 0.7

Commands that return payload data use the format:

<command character> is one character from the set: [a-z]

<command type> is one character for the set: [0-9]

<command payload> is variable in length.

<CR> is the command terminator.

The command character is the "lower case" version of the local host command.

6.1. User configuration methods

The user can interface with the Raw Serial Module in three distinct ways:

· Dumb Terminal – debug environment or field updates

· Windows GUI/Application – debug mode or field upgrade

· Batch mode – manufacturing environment usage

6.2. Operating Modes

The module interface has two modes:

· BT Link Active state: In this case the Serial Interface looks like a raw serial port

(TxD,RxD,CTS, etc. and GND). There is no intelligence in the BT module

present from the Serial Interface perspective. This mode does not support the

command and control modes described below.

· BT Link Inactive state

: this mode exists when a BT link is not existent: In this

case the Serial Interface looks like a serial port that supports a number of

command and control modes.

Upon reset the unit comes up in “BT Link Inactive State”. After the first Bluetooth

connection, the unit goes into “BT Link Active State”. It will stay in this state until the link is

lost because the Master shuts it down, or there is an out-of-range condition. At this point it

will return to the “BT Link Inactive State”.

6.3. Command and Control Modes

Note that these commands are only available over the serial link, not over the air and are not

available when the device is in the BT Link Active state.
