RN41/RN41N 1.0 DEVICE OVERVIEW FIGURE 1-1: RN41/RN41N TO MCU INTERFACE
The RN41/RN41N 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 RN41/RN41N supports multiple interface protocols, is simple to design in, and is fully certified, making it a complete embedded Bluetooth solution. With its high-performance, chip antenna (RN41) or external antenna (RN41N), and support for Bluetooth EDR, the RN41/RN41N delivers up to a 3-Mbps data rate for distances up to 100 meters.
1.1 MCU Interface
The RN41/RN41N module is managed through ASCII commands via the UART and/or PIO signals. A MCU Table 1-1, Table 1-2, Table 1-3, Table 1-4, and Table 1- (micro-controller-unit) or host processor sends com- 5 provide the module’s environmental conditions, elec- mands to module to configure features, read status, trical characteristics, dimensions, radio characteristics, and manage Bluetooth data connections. and digital I/O characteristics. As shown in Figure 1-1, the UART TX and RX are required to communicate with module and transfer data

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.
