... Asset tracking • Description The RN-41 module is a small form factor, low power, class 1 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 RN-41 supports multiple interface protocols, is simple to design in, and is fully certified, making it a complete embedded Bluetooth solution ...

... 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-41-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. Roving Networks recommends the Yageo chip antenna for the RN-41-N module. For detailed information on this antenna, refer to the Yageo chip antenna data sheet on the Support page of the Roving Networks website at http://www ...
