RN42/RN42N

1.0 DEVICE OVERVIEW

The RN42/RN42N module is a small form factor, low­power, class 2 Bluetooth radio that is ideal for
designers who want to add wireless capability to their
products without spending significant time and money
developing Bluetooth-specific hardware and software.
The RN42/RN42N supports multiple interface
protocols, is simple to design in, and is fully certified,
making it a complete embedded Bluetooth solution.
With its high-performance, PCB trace antenna (RN42)
or external antenna (RN42N), and support for
Bluetooth EDR, the RN42/RN42N delivers up to a 3­Mbps data rate for distances up to 10 meters.

1.1 MCU Interface

The RN42/RN42N module is managed through ASCII
commands via the UART and/or PIO signals. A micro­controller unit (MCU) or host processor sends com­mands to configure module features, read status, and
manage Bluetooth data connections.

As shown in Figure 1-1, the UART TX and RX are
required to communicate with module, and transfer
data across Bluetooth SPP connection.

Connecting the hardware flow control lines CTS and
RTS is highly recommended for applications that
transmits a continuous stream of data.

The module can be configured locally via the UART or
over-the-air. To support instant cable replacement,
auto-discovery/pairing does not require software con­figuration. Additionally, the module supports auto-con­nect master, I/O pin (DTR), and character-based trigger
modes.

2.0 APPLICATION INFORMATION

The following sections provide information on design­ing with the RN42/RN42N module, including radio
interference, factory reset, solder reflow profile, con­nection status, and so on.

2.1 Reset Circuit

The RN42/RN42N contains a weak internal pull-up to
VCC, and the reset polarity is active low. The module’s
reset pin has an optional Power-on Reset circuit with a
delay, which 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 I/O is available to generate the reset
once power is stable. If not, designers can use one of
the many low-cost power supervisor chips available,
such as the MCP809 or MCP102/121.

2.2 Factory Reset Using GPIO4

It is recommended to connect the GPIO4 pin to a
switch, jumper, or resistor so it can be accessed. This
pin can be used to reset the module to its factory
default settings, which is critical in situations where the
module has been misconfigure d. To reset the module
to the factory defaults, GPIO4 should be high on
power-up and then toggle between low and high twice
with a 1 second wait between the low-high transitions.

2.4 Module Mounting Details

Figure 2-1 and Figure 2-2 show the recommended

PCB footprint for the RN42 and RN42N, respectively.
When laying out the carrier board for the RN42 module,
the areas under the antenna and shielding connections
should not have surface traces, ground planes, or
exposed vias.

Figure 2-3 and Figure 2-4 show the recommended

mounting details for the RN42 and RN42N, respec­tively. For optimal radio performance, the RN42 mod­ule’s antenna end should protrude at least 31 mm
beyond any metal enclosure.

Figure 2-5 shows examples of good, bad, and accept-

able positioning of the RN42/RN42N on the host PCB.

2.5 External Antenna Types (RN42N)

The RN42N module’s antenna pin (pin 26) provides a
50-ohm impedance to external antennas. Pin 25 can
connect directly to a coaxial cable or to an antenna
connector such as a U.FL or reverse polarity SMA.

The PCB trace from pin 26 to the coaxial cable or con­nector should be less than 0.2 inches (5 mm) for mini­mum loss and the best impedance match. If the PCB
trace is longer, it should be a 50-ohm impedance
microstrip trace. Connect adjacent ground pins 25 and
27 to a low-impedance ground on the host PCB and the
antenna connection. Figure 2-4 gives example host
PCB layout to a U.FL connector.

2.6 HCI Mode

Microchip offers the Host Controller Interface (HCI)
mode in addition to the standard operational mode of its
Bluetooth modules (standard mode refers to the on­board stack running on the module).

In HCI mode, the on-board stack is bypassed and the
module is put in a state that runs the Bluetooth base­band. The HCI provides a command reference inter­face to the baseband controller and the link manager,
and provides access to the hardware status and control
registers. This interface provides a uniform method for
accessing the Bluetooth baseband capabilities.

In this mode, the Bluetooth stack is no longer on-board
the module. It is offloaded to the interfacing host pro­cessor. The Bluetooth module is used as a radio, per­forming the lower level MAC functionalities, while the
application stack runs on the host processor.

Using the module in HCI mode enables designers to
implement profiles that are not natively supported on
the Bluetooth module.

Note: HCI mode is only available by ordering

part RN42HCI and RN42HCI for UART
interface; or RN42U and RN42U for USB
interface.

Microchip offers HCI mode in two hardware interfaces:

• HCI over UART (RN42HCI-I/RM)

• HCI over USB (RN42U-I/RM)

2.6.1 HCI OVER UART

In this mode, the hardware interface between the host
processor and the Bluetooth module is the UART con­figured at 115.2Kbps. The UART hardware flow control
signals are required between the host processor and
the Bluetooth module for the HCI interface to work.
Failure to do so can cause the host processor and the
Bluetooth module to become out of sync and break the
Bluetooth link.

2.6.2 HCI OVER USB

In this mode, the hardware interface between the host
processor and the Bluetooth module is the USB. In this
architecture, the Bluetooth module is the USB slave
and the host processor is the USB host.

Using the USB interface offers the advantage of a
faster data link between the Bluetooth module and the
host processor. With this interface, it is possible to
achieve Bluetooth’s theoretical maximum throughput of
3 Mpbs.

2.7 Soldering Recommendations

The RN42/RN42N wireless module was assembled
using standard lead-free reflow profile IPC/JEDEC J­STD-020.

The module can be soldered to the host PCB using
standard leaded and lead-free solder reflow profiles.

To avoid damaging the module, the following recom­mendations are given:

• Microchip Technology Application Note,” AN233
Solder Reflow Recommendation” (DS00233) pro­vides solder reflow recommendations

• Do not exceed peak temperature (T

• Refer to the Solder Paste data sheet for specific
reflow profile recommendations

• Use no-clean flux solder paste

• Do not wash as moisture can be trapped under
the shield

• Use only one flow. If the PCB requires multiple
flows, apply the module on the final flow.

2.8 SPI Interface

) of 250 C°

p

The SPI Interface is primarily used for factory program­ming, test, and diagnostics. Although not required, the
SPI interface is useful for restoring a corrupted flash
image or enabling test modes required for certification
testing.

When module is installed in a final product that requires
European type approval, see Section 3.3 “Europe”, it
is recommended that the SPI interface should be
accessible via 6-pin header as shown in Figure 2-6.

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.

INCLUDING BUT NOT LIMITED TO ITS CONDITION,
