ing with the RN-41/RN-41N module, including radio interference, factory reset, solder reflow profile, con-
nection status, etc. Reset Circuit 2.1 The RN-41/RN-41N contains a 1k pullup to VCC, and the reset polarity is active low. The modules 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 insta-
bility on power up. Often a microcontroller or embed-
ded 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 currntly avail-
able, such as the MCP809 or MCP102/121. Factory Reset Using GPIO4 2.2 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 misconfigured. To reset the module to the factory defaults, GPIO4 should be high on power-up and then toggle low, high, low, high with a 1 second wait between the transitions. 2.4 Using the SPI Bus to Upgrade the Flash Memory While not required, this bus is very useful for configur-
ing the Bluetooth modules advanced parameters. The bus is required when upgrading the modules firmware. The typical application schematic shown in Figure 2-6 shows a 6-pin header that can be implemented to gain access to this bus. A minimum-mode version might simply use the SPI signals (4 pins) and obtain ground and VCC from elsewhere in the design. Module Mounting Details 2.5 Figure 2-1 and Figure 2-2 show the recommended PCB footprint for the RN-41 and RN-41N, respectively. When laying out the carrier board for the RN-41 mod-
ule, the areas under the antenna and shielding connec-
tions should not have surface traces, ground planes, or exposed vias. Figure 2-3 and Figure 2-4 show the recommended mounting details for the RN-41 and RN-41N, respec-
tively. For optimal radio performance, the RN-41 mod-
ules antenna end should protrude at least 31 mm beyond any metal enclosure. FIGURE 2-1:
RN-41 RECOMMENDED PCB FOOTPRINT
Connection Status 2.3 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 Table 2-2. TABLE 2-1:
GPIO5 STATUS GPIO5 Status Toggle at 1 Hz Toggle at 10 Hz Low Description The module is discoverable and waiting for a connection. The module is in command mode. The module is connected to another device over Bluetooth. TABLE 2-2:

Pin 25 can connect directly to a coaxial cable antenna or to an antenna connector such as a U.FL or reverse polarity SMA. The PCB trace from pin 25 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 24 and 26 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. Modular certification of the RN171 module was per-
formed with the external antenna types listed in Table 2-3. Refer to Section 3.0, Regulatory Approval for specific regulatory requirements by country. TABLE 2-3:
TESTED EXTERNAL ANTENNA TYPES Type Gain (dBi) Monopole Dipole Yagi 0.56 8 15 HCI Mode 2.7 Roving Networks 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 allows designers to implement profiles that are not natively supported on the Bluetooth module. Note:
HCI mode requires a separate firmware build that must be loaded into the mod-
ules flash at the factory. Is not upgrade-
able in the field. www.rovingnetworks.com Version 3.43 5/21/13 page 8 RN41-DS Roving Networks offers HCI mode in two hardware interfaces:
HCI over UART (RN-41HCI-I/RM) HCI over USB (RN-41U-I/RM) HCI OVER UART 2.7.1 In this mode, the hardware interface between the host processor and the Bluetooth module is the UART. You must interface the flow control signals between the host processor and the Bluetooth module for the HCI inter-
face to work. Failure to do so can cause the host pro-
cessor and the Bluetooth module to become out of sync and break the Bluetooth link. HCI OVER USB 2.7.2 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 architecture, it is possible to achieve Bluetooths theoretical maximum throughput of 3 Mpbs. Solder Reflow Profile 2.8 The lead-free solder reflow temperature and times are:

(1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation 3.0 REGULATORY APPROVAL This section outlines the regulatory information for the RN-41/RN-41N module for the following countries:
United States Canada Europe Australia New Zealand United States 3.1 The RN-41/RN-41N module has received Federal Communications Commission (FCC) CFR47 Telecom-
munications, Part 15 Subpart C Intentional Radiators modular approval in accordance with Part 15.212 Mod-
ular Transmitter approval. Modular approval allows the end user to integrate the RN-41/RN-41N module into a finished product without obtaining subsequent and sep-
arate FCC approvals for intentional radiation, provided no changes or modifications are made to the module circuitry. Changes or modifications could void the users authority to operate the equipment. The end user must comply with all of the instructions provided by the Grantee, which indicate installation and/or oper-
ating 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. www.rovingnetworks.com Version 3.43 5/21/13 page 11 A users manual for the product should include the fol-
lowing statement:
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 equip-
ment generates, uses and can radiate radio fre-
quency 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 follow-
ing 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 con-
nected. Consult the dealer or an experienced radio/TV technician for help. Additional information on labeling and user information requirements for Part 15 devices can be found in KDB Publication 784748 available at the FCC Office of Engi-
neering and Technology (OET) Laboratory Division Knowledge Database (KDB) http://apps.fcc.gov/oetcf/
kdb/index.cfm. RF EXPOSURE 3.1.2 All transmitters regulated by FCC must comply with RF exposure requirements. OET Bulletin 65, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields, provides assistance in determining whether proposed or existing transmitting facilities, operations or devices comply with limits for human exposure to Radio Frequency
(RF) fields adopted by the Federal Communications Commission (FCC). The bulletin offers guidelines and suggestions for evaluating compliance. If appropriate, compliance with exposure guidelines for mobile and unlicensed devices can be accomplished by the use of warning labels and by providing users with information concerning minimum separation dis-
tances from transmitting structures and proper installa-
tion of antennas. RN41-DS The following statement must be included as a CAU-
TION statement in manuals and OEM products to alert users of FCC RF exposure compliance:
To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons dur-
ing operation. To ensure compliance, operation at closer than this distance is not recommended. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. If the RN-41/RN-41N module is used in a portable application (i.e., the antenna is less than 20 cm from persons during operation), the integrator is responsible for performing Specific Absorption Rate (SAR) testing in accordance with FCC rules 2.1091. 3.1.3 APPROVED EXTERNAL ANTENNA TYPES To maintain modular approval in the United States, only the antenna types that have been tested shall be used. It is permissible to use different antenna manufacturer provided the same antenna type and antenna gain
(equal to or less than) is used. Testing of the RN-41N module was performed with the antenna types listed in Table 2-3. HELPFUL WEB SITES 3.1.4 Federal Communications Commission http://www.fcc.gov FCC Office of Engineering and Technology (OET) Lab-

The RN-41N module can only be sold or operated with antennas with which it was approved. Transmitter may be approved with multiple antenna types. An antenna type comprises antennas having similar in-band and out-of-band radiation patterns. Testing shall be per-
formed using the highest gain antenna of each combi-
nation of transmitter and antenna type for which approval is being sought, with the transmitter output power set at the maximum level. Any antenna of the same type having equal or lesser gain as an antenna that had been successfully tested with the transmitter, will also be considered approved with the transmitter, and may be used and marketed with the transmitter. When a measurement at the antenna connector is used to determine RF output power, the effective gain of the device's antenna shall be stated, based on mea-
surement or on data from the antenna manufacturer. For transmitters of output power greater than 10 milli-
watts, the total antenna gain shall be added to the mea-
sured RF output power to demonstrate compliance to the specified radiated power limits. Approved external antenna types for the RN-41N mod-
ule are listed in Table 2-3. www.rovingnetworks.com Version 3.43 5/21/13 page 13 RN41-DS ANTENNA REQUIREMENTS 3.3.2 From R&TTE Compliance Association document Tech-
