Set device name as “abcdefg”. Save and Rest.
4. Auto-connect the last paired device on power
\r\n+STAUTO=0\r\n
Auto-connect forbidden. Save and Rest.
\r\n+STAUTO=1\r\n
Permit Auto-connect. Save and Rest.
5. Permit Paired device to connect me
\r\n+STOAUT=0\r\n
Forbidden. Save and Rest.
\r\n+STOAUT=1\r\n
Permit. Save and Rest.
6. Set PINCODE
\r\n +STPIN=2222\r\n
Set pincode “2222”, Save and Rest.
7. Delete PINCODE(input PINCODE by MCU)
\r\n+DLPIN\r\n Delete pincode. Save and Rest.
8. Read local ADDRESS CODE
\r\n+RTADDR\r\n Return address of the device.
9. Auto-reconnect the device when they loss connection.
\r\n+LOSSRECONN=0\r\n
Forbid auto-reconnecting.
\r\n+LOSSRECONN=1\r\n
Permit auto-reconnecting.
Commands for Normal Operation:
1. Inquire
a) Master
\r\n+INQ=0\r\n Stop Inquiring
\r\n+INQ=1\r\n Begin/Restart Inquiring
a) Slave
\r\n+INQ=0\r\n Disable been inquired
\r\n+INQ=1\r\n Enable been inquired
When +INQ=1 command is successful, the red and green LEDS blink
alternatively.
2. Bluetooth module returns inquiring result
\r\n+RTINQ=aa,bb,cc,dd,ee,ff;name\r\n
Serial Bluetooth device with the address
“aa,bb,cc,dd,ee,ff” and the name
3. Connect device
\r\n+CONN=aa,bb,cc,dd,ee,ff\r\n Connect to a device with address of
"aa,bb,cc,dd,ee,ff”
4. Bluetooth module requests inputting PINCODE
\r\n+INPIN\r\n
5. Input PINCODE
\r\n+RTPIN=code\r\n
Example: RTPIN=0000, Input PINCODE which is four zero.
6. Return status \r\n+BTSTA:xx\r\n
xx status:
0 - Initializing

3 - Connecting
4 - Connected
(Note: This is not a command, but the information returned from the module after
every command)
Warning: Changes or modifications to this unit not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determined
by turning the equipment off and on, the user is encouraged to try to correct the interference by one
or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause
undesired operation.
OEM Installation Instruction
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment is installed and operated without distance limited between the radiator
& your body. This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter. This device is intended only for OEM integrators under the following
conditions:
The transmitter module may not be co-located with any other transmitter or antenna.
As long as the condition above are met, further transmitter test will not be required. However, the
OEM integrator is still responsible for testing their end-product for any additional compliance
requirements required with this module installed (for example, digital device emissions, PC
peripheral requirements, etc.).
Maximum antenna gain with this device is -1dBi.
IMPORTANT NOTE: In the event that these conditions cannot be met (for example certain laptop
configurations or co-location with another transmitter), then the FCC authorizations are no longer
considered valid and the FCC ID cannot be used on the final product. In these circumstances, the
OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and
obtaining separate FCC authorizations.
End Product Labeling
The final end product must be labeled in a visible area with the
following: “Contains Transmitter Module FCC ID: Z4T-BTSHIELD” or “Contains FCC ID:
Z4T-BTSHIELD” .
Manual Information That Must be Included
The user’s manual for end users must include the following in-formation in a prominent location.
IMPORTANT NOTE:
To comply with FCC RF exposure compliance requirements, the antenna used for this transmitter
must not be collocated or operating in conjunction with any other antenna or transmitter.
Other notes:
Bluetooth Shield modules have been built or under development for near body exposure
applications. Because absorption rate testing (commonly known as SAR or Specific absorption rate)
is not modularly transferable for FCC/IC. Thus, if the module is installed in the final device, the
end user is still responsible to evaluate RF exposure testing (for USA, please refer to the following):
• FCC Part 1.1307
• FCC Part 2.1091 Mobile Devices
• FCC Part 2.1093 Portable Devices
