7 Design Concerns
7.1
Reset circuit
RN-42 contains a 1k pull up to VCC, the polarity of reset on the RN42 is ACTIVE LOW.
A power on reset circuit with delay is OPTIONAL on the reset pin of the module. It should
only be required if the input power supply has a very slow ramp, or tends to bounce or
have instability on power up. Often a microcontroller or embedded CPU IO is available to
generate reset once power is stable. If not, there are many low cost power supervisor
chips available, such as MCP809, MCP102/121, and Torex XC61F.
7.2
Factory reset PIO4
It is a good idea to connect this pin to a switch, or jumper, or resistor, so it can be
accessed. This pin can be used to reset the module to FACTORY DEFAULTS and is
often critical in situations where the module has been mis-configured. To set Factory
defaults start HIGH, then toggle times.
7.3
Connection status
PIO5 is available to drive an LED, and blinks at various speeds to indicate status.
PIO2 is an output which directly reflects the connection state, it goes HIGH when
connected, and LOW otherwise.
7.4
HCI mode
The RN42 module must be loaded with special firmware to run in HCI mode. When in
HCI mode the standard SPP/DUN applications are disabled.
7.5
Using SPI bus for flash upgrade
While not required, this bus is very useful for configuring advanced
parameters of the Bluetooth modules, and is required for upgrading the firmware on
modules. The suggested ref-design shows a 6pin header which can be implemented to
gain access to this bus. A minimum-mode version could just use the SPI signals (4pins)
and pickup ground and VCC from elsewhere on the design.

7.6
Minimizing radio interface
When laying out the carrier board
for the RN42 module the areas
under the antenna and shielding
connections should not have
surface traces, GND planes, or
exposed vias. (See diagram to right)
For optimal radio performance the
antenna end of RN42 module
should protrude 5mm past any
metal enclosure.
7.7
Soldering reflow profile
Lead-Free Solder Reflow
Temp: 230 degree C, 30-40 seconds, Peak 250 degree C maximum.
Preheat temp: 165 +- 15 degree C, 90 to 120 seconds.

Compliance Information
FCC Compliance Statement:
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. This device must
accept any interference received, including interference that may cause
undesired operation. Product that is a radio transmitter is labeled with FCC
ID.
FCC Caution:
(1) Exposure to Radio Frequency Radiation. This equipment must be
installed and operated in accordance with provided instructions and the
antenna(s) used for this transmitter must be installed to provide a
separation distance of at least 20 cm from all persons and must not be
collocated or operating in conjunction with any other antenna or
transmitter.
End-users and installers must be provided with antenna installation
instructions and transmitter operating conditions for satisfying RF exposure
compliance.
(2) Any changes or modifications not expressly approved by the grantee
of this device could void the user's authority to operate the equipment.
(3) This Transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter.
(4) Changes or modifications to this unit not expressly approved by the
party responsible for compliance could void the user authority to operate
the equipment.
(5) Outdoor Operations in the 5.15~5.25GHz band is prohibited.
NOTE:
(1) This device is approved for OEM installation with specified antennas as
listed in this Manual. It is the responsibility of the Installer to comply with the
separation distance for satisfying RF exposure compliance.
(2) This device only could work when being installed into “client devices”
which could not transmit automatically, such as Notebook P.C. , with the
software driver limit.
IMPORTANT NOTE: In the event that these conditions can not be met (for
example certain laptop configurations or co-location with another
transmitter), then the FCC authorization is no longer considered valid and
the FCC ID can not 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 a separate FCC authorization.
IC Radiation Exposure Statement for Canada
This equipment complies with IC radiation exposure limits set forth for an
uncontrolled enviroment. To maintain compliance with IC RF exposure
compliance requirements, Please avoid direct contact to the transmitting.
End users must follow the specific operating instructions for satisfying RF
Exposure compliance.
Caution: The device is incapable of transmitting in the band 5600-5650 MHz
band in Canada.
