www.rovingnetworks.com Version 3.43 5/21/13 page 6 RN41-DS2.0 APPLICATION INFORMATIONThe following sections provide information on design-ing with the RN-41/RN-41N module, including radiointerference, factory reset, solder reflow profile, con-nection status, etc.2.1 Reset CircuitThe RN-41/RN-41N contains a 1k pullup to VCC, andthe reset polarity is active low. The module’s reset pinhas an optional power-on-reset circuit with a delay,which should only be required if the input power supplyhas 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 oncepower is stable. If not, designers can use one of themany low-cost power supervisor chips currntly avail-able, such as the MCP809 or MCP102/121.2.2 Factory Reset Using GPIO4It is recommended to connect the GPIO4 pin to aswitch, jumper, or resistor so it can be accessed. Thispin can be used to reset the module to its factorydefault settings, which is critical in situations where themodule has been misconfigured. To reset the moduleto the factory defaults, GPIO4 should be high onpower-up and then toggle low, high, low, high with a 1second wait between the transitions.2.3 Connection StatusGPIO5 is available to drive an LED, and it blinks at var-ious speeds to indicate status (see Ta b l e 2 - 1 ). GPIO2is an output that directly reflects the connection state asshown in Table 2-2.2.4 Using the SPI Bus to Upgrade the Flash MemoryWhile not required, this bus is very useful for configur-ing the Bluetooth modules’ advanced parameters. Thebus is required when upgrading the module’s firmware.The typical application schematic shown in Figure 2-6shows a 6-pin header that can be implemented to gainaccess to this bus. A minimum-mode version mightsimply use the SPI signals (4 pins) and obtain groundand VCC from elsewhere in the design.2.5 Module Mounting DetailsFigure 2-1 and Figure 2-2 show the recommendedPCB 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, orexposed vias. Figure 2-3 and Figure 2-4 show the recommendedmounting details for the RN-41 and RN-41N, respec-tively. For optimal radio performance, the RN-41 mod-ule’s antenna end should protrude at least 31 mmbeyond any metal enclosure.

Pin 25 canconnect directly to a coaxial cable antenna or to anantenna connector such as a U.FL or reverse polaritySMA. 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 PCBtrace is longer, it should be a 50-ohm impedancemicrostrip trace. Connect adjacent ground pins 24 and26 to a low-impedance ground on the host PCB and theantenna connection. Figure 2-4 gives example hostPCB layout to a U.FL connector.Modular certification of the RN171 module was per-formed with the external antenna types listed inTable 2- 3 . Refer to Section 3.0, Regulatory Approvalfor specific regulatory requirements by country.2.7 HCI ModeRoving Networks offers the Host Controller Interface(HCI) mode in addition to the standard operationalmode of its Bluetooth modules (standard mode refersto the on-board stack running on the module).In HCI mode, the on-board stack is bypassed and themodule 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 controlregisters. This interface provides a uniform method foraccessing the Bluetooth baseband capabilities.In this mode, the Bluetooth stack is no longer on-boardthe 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 theapplication stack runs on the host processor.Using the module in HCI mode allows designers toimplement profiles that are not natively supported onthe Bluetooth module.No CopperIn these AreasRN-41OkayRN-41Best RN-41OkayRN-41OkayTABLE 2-3: TESTED EXTERNAL ANTENNA TYPESType Gain (dBi)Monopole 0.56Dipole 8 Yagi 15Note: HCI mode requires a separate firmwarebuild that must be loaded into the mod-ule’s flash at the factory.

www.rovingnetworks.com Version 3.43 5/21/13 page 9 RN41-DSRoving Networks offers HCI mode in two hardwareinterfaces:• HCI over UART (RN-41HCI-I/RM)• HCI over USB (RN-41U-I/RM)2.7.1 HCI OVER UARTIn this mode, the hardware interface between the hostprocessor and the Bluetooth module is the UART. Youmust interface the flow control signals between the hostprocessor 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 ofsync and break the Bluetooth link.2.7.2 HCI OVER USBIn this mode, the hardware interface between the hostprocessor and the Bluetooth module is the USB. In thisarchitecture, the Bluetooth module is the USB slaveand the host processor is the USB host.Using the USB interface offers the advantage of afaster data link between the Bluetooth module and thehost processor. With this architecture, it is possible toachieve Bluetooth’s theoretical maximum throughput of3 Mpbs.2.8 Solder Reflow ProfileThe lead-free solder reflow temperature and times are:•Temperature—230° C, 30 - 40 seconds, peak 250° C maximum•Preheat temperature—165° ± 15° C, 90 to 120 seconds•Time—Single pass, one time

L'exploitation est autorisée aux deux con-ditions suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.Under Industry Canada regulations, this radio trans-mitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the trans-mitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropi-cally radiated power (e.i.r.p.) is not more than that necessary for successful communication.Conformément à la réglementation d'Industrie Can-ada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Can-ada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante.
