... Computer accessories Description The RN- small form factor, low power, class 2 Bluetooth radio for designer’s who want to add wireless capability to their products. The RN-42 supports multiple interface protocols, is simple to design in, and is fully certified, making it a complete embedded Bluetooth solution. The RN-42 is functionally compatible with the RN 41 ...

... After Two Walls After Three Walls The readings shown in Table 6 are approximate and may vary depending upon the RF environment. Bluetooth hops in a pseudo-random fashion over the 79 frequencies in the ISM band to adapt to the interference. Data throughput and range vary depending on the RF interference environment. ...

... MCP809, MCP102/121, and Torex XC61F. Factory Reset Using GPIO4 Roving Networks recommends that designers 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 ...

... 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 module’s flash at the factory. Is not upgradeable in the field. Roving Networks offers HCI mode in two hardware interfaces: HCI over UART • HCI over USB • ...

... Because the RN-42-N does not contain an antenna, it does not carry regulatory approvals. If designers use Roving Networks recommended design, they can file for a permissible antenna change and use Roving Networks’ regulatory approvals. The recommended antenna design for the RN- PCB trace antenna. To meet the regulatory compliance information, customers must use the trace pattern shown in Figure 6 ...
