Bluetooth Module Description and User Manual
June 1, 2008
John Gardner
The BT Module is designed to be used as a common BT element in Metrologic
products. The Class 2 BlueTooth module is designed to provide Class 2
BlueTooth performance for our Smartdongle product as a master BlueTooth unit
and for integration into the scanners as slave BlueTooth unit. The BlueTooth
module has been tested to meet FCC rules and regulation for the ISM band of
2.4Ghz to 4.48Ghz. The unit can not be modified without retesting All units that
use this module must contain the language “ Contains FCC ID LW5BT010M” for
this module.
The Module supports Bluetooth Serial Port Profile (SPP) control application
based on this BlueLab software stack. The BlueTooth module must be tested in
the final product to meet applicable FCC regulations for units that contain a
limited module approval. Our application implement a UART command set (AT
command set) to control the SPP together with I/O control and indicator. The
HOST MCU uses these commands and I/O to control the Bluetooth.
Bluetooth Features supported:
Besides making connection and data transmission, the module will provide following
Bluetooth features.

DATA/CMD in The incoming data to BT module is command or data.
WAKE UP

HOST SLEEP in Reserved
Implement the module in scanner:
1. On power up, Host reset the BT Module, and wait the BT Module self test by
checking the READY PIN status, The Module will be ready less than 1 second.
2. Host switch to CMD mode by set the DATA/CMD pin to HIGH.
3. Host configure the module:
• Change the communication baudrate if necessary.
• Read the BT module address.
• Set the BT Module device name.
• Set the class if needed.
• Set the security mode if necessary.
Host set the security mode with ATC command:
e.g. “ATC=3000” + 0x0D,
The Module will reply a ‘0’ + 0x0D after it configure correctly.
4. Host initiate the connection by the ATD command:
e.g. “ATD=00046184FB71”
The Module will reply a ‘0’ + 0x0D after it received correctly.
The host only needs to send this connect command for one time, the BT Module
will try the connection until it connected or it receives an “ATH” command.
Once send the connect command, the host only need to monitor the
CONNECTED pin status, once the connection is established, the CONNECTED
pin will be HIGH.
5. After the connection established, the BT Module will pull up the CONNECTED
pin and then present UART information “Y” + 0x0D if the UART connection
indicator is enabled.
6. The Host switch to the DATA mode by set the DATA/CMD pin to LOW. Then it
can send barcodes through the Bluetooth interface.
7. During the connection:
When the connection broken, the BT module will pull down the CONNECTED pin
and present a UART information “Z” + 0x0D, if the UART connection indicator is
enabled.
If the connection lost automatically such as the scanner is out of range, then the
CONNECT pin will be LOW, the Module will try reconnection by itself.
If the HOST switch to the command mode and send the “ATH” command to
disconnect the connection, the Module will not try reconnection by itself. The
HOST should send the ATD + ADDRESS + 0x0D command to restart the
connection process.
If the HOST need to switch to a new Bluetooth device, then it should send the
“ATH” command first, and then send the ATD + ADDRESS + 0x0D, the Module
will retry the connection with the new address.
b. Implement the module in cradle/dongle:
1. On power up, Host reset the BT Module, and wait the BT Module self test by
checking the READY PIN status, The Module will be ready less than 1 second.
2. Host switch to CMD mode by set the DATA/CMD pin to HIGH.
3. Host configure the module:
• Change the communication baudrate if necessary.
• Read the BT module address.
• Set the BT Module device name.
• Set the class if needed.
• Set the security mode if necessary.
Host set the security mode with ATC command:
e.g. “ATC=3000” + 0x0D,
The Module will reply a ‘0’ + 0x0D after it configure correctly.
4. Host monitor the CONNECT pin status, once the pin is HIGH, the MCU could
switch to the data mode and ready to receive the data.

• Set the security mode if necessary.
Host set the security mode with ATC command:
e.g. “ATC=3000” + 0x0D,
The Module will reply a ‘0’ + 0x0D after it configure correctly.
4. Host monitor the CONNECT pin status, once the pin is HIGH, the MCU could
switch to the data mode and ready to receive the data.
Integrators Responsibility
1) The BT Module has a limited module approval and should not be changed
without recertification.
2) The MPE calculations need to be checked based on the location of the unit with
reference to the user. See applicable FCC guidelines governing MPE and SAR
testing.
3) The end product needs to in clued “ This product contains FCC ID
LW5BT010M”
4) All applicable FCC warnings need to be in the end users manual.
FCC RF Radiation Exposure Statement for both module and OEM integrator:
1. This Transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
2. This equipment complies with FCC RF radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with a
minimum distance of 20 centimeters between the radiator and your body.
