RN42/RN42N

1.0 DEVICE OVERVIEW

The RN42/RN42N module is a small form factor, low-

power, 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 3-

Mbps 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 micro-

controller unit (MCU) or host processor sends com-

mands 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 con-

figuration. Additionally, the module supports auto-con-

nect master, I/O pin (DTR), and character-based trigger

modes.

RN42/RN42N

2.0 APPLICATION INFORMATION

The following sections provide information on design-

ing with the RN42/RN42N module, including radio

interference, factory reset, solder reflow profile, con-

nection 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.

2.3 Connection Status

GPIO5 is available to drive an LED, and it blinks at var-

ious speeds to indicate status, see Table 2-1. GPIO2 is

an output that directly reflects the connection state as

shown in Ta b l e 2 - 2 .

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, respec-

tively. For optimal radio performance, the RN42 mod-

ule’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.

RN42/RN42N

FIGURE 2-5: RN42 HOST PCB EXAMPLE LAYOUT

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 con-

nector should be less than 0.2 inches (5 mm) for mini-

mum 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 on-

board 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 base-

band. The HCI provides a command reference inter-

face 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 pro-

cessor. The Bluetooth module is used as a radio, per-

forming 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.

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 con-

figured 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 J-

STD-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 recom-

mendations are given:

• Microchip Technology Application Note,” AN233

Solder Reflow Recommendation” (DS00233) pro-

vides solder reflow recommendations

• Do not exceed peak temperature (Tp) of 250 C°

• 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

The SPI Interface is primarily used for factory program-

ming, 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.

FIGURE 2-6: OPTIONAL SPI

INTERFACE

2.9 Bluetooth SIG QDID

The RN42 has a QDID registered with the Bluetooth

SIG. The manufacturer using the RN42 module in their

end product can reference this QDID when filing an

EPL (end product listing) to use Bluetooth® brand and

logo. For more information, please visit the Bluetooth

tions Commission (FCC) CFR47 Telecommunications,

Part 15 Subpart C “Intentional Radiators” modular

approval in accordance with Part 15.212 Modular

Transmitter approval. Modular approval allows the end

user to integrate the RN42 module into a finished prod-

uct without obtaining subsequent and separate FCC

approvals for intentional radiation, provided no

changes or modifications are made to the module cir-

cuitry. Changes or modifications could void the user’s

authority to operate the equipment. The end user must

comply with all of the instructions provided by the

Grantee, which indicate installation and/or operating

conditions necessary for compliance.

The finished product is required to comply with all appli-

cable FCC equipment authorizations regulations,

requirements and equipment functions not associated

with the transmitter module portion. For example, com-

pliance must be demonstrated to regulations for other

transmitter components within the host product; to

requirements for unintentional radiators (Part 15 Sub-

part B “Unintentional Radiators”), such as digital

devices, computer peripherals, radio receivers, etc.;

and to additional authorization requirements for the

non-transmitter functions on the transmitter module

(i.e., Verification, or Declaration of Conformity) (e.g.,

transmitter modules may also contain digital logic func-

tions) as appropriate.

3.1.1 LABELING AND USER
