The working principle of the RN4871-V/RM118 is based on the integration of two main components: the Bluetooth radio and the MCU. The Bluetooth radio is responsible for giving the device the capability to communicate wirelessly, while the MCU coordinates communication tasks and performs the required automation and control tasks.

The Bluetooth radio uses frequency modulation to transmit data. The radio receives data from a base station and transmits it in the form of packets. These packets are received by the other Bluetooth radio and decoded. The MCU processes the data and performs the tasks according to the application code. The data is processed and stored in the device memory. The MCU then sends a control signal to the Bluetooth radio, which then transmits the response back to the base station.

The radio and the MCU also provide diagnostic and management features. The radio can be programmed to report errors, while the MCU can track the performance of the device and report errors. Additionally, the MCU provides the ability to set up security measures, such as PINs, passwords and others.

In conclusion, the RN4871-V/RM118 is a high-performance ultra-low power transceiver module with integrated Bluetooth 4.2 and a variety of front-end features. It has been designed to enable robust and reliable data transmission for remote control and wireless applications, and is the ideal solution for low-power applications with long range, low latency, and reliable data transmission.
