1.0 Introduction

This manual is only applicable to PCBA COMMUNICATION MODULE.

2.0 General

The main components of the Bluetooth receiver include Bluetooth module, RF chips (CMT2210LH),

MCU, antenna and antenna circuits.

Bluetooth receiver is mainly composed of RF receiving IC, microprocessor and bluetooth module.

The microprocessor is the main body of bluetooth receiver, which is used to process and control signals.

RF receiving IC can realize the ook demodulation of the wall control signal and output the control

signal after analysis and processing by the microprocessor.The application of bluetooth module realizes

the convenient network connection between devices within a short distance.People can control the

devices by moving them within a certain distance. The bluetooth module sends and receives signals in

this way.

The following is a detailed description of these components

2.1 Bluetooth module Description

design. The product's 26MHz crystal provides the PLL's reference frequency and digital clock, supports OOK demodulation output with data rate of 1.0-5.0Ksps, and supports time-configurable periodic reset to avoid crashes caused by various external causes. The CMT2210LH supports two voltage range operating scenarios, which can be used in 5V system applications or as a 3V system application.

Real Designs CSR recommends keeping metal objects as far away from the antenna as possible. Keeping metallic objects out of the near field is usually adequate. Dielectric materials (like plastic or FR-4) detune an antenna by lowering its resonant frequency. The effect is not as serious as placing an antenna next to metal objects and can be corrected by reducing the length of the antenna. Therefore it is important for the antenna to be tuned when it is in the product.

The host product with the module installed must be evaluated for simultaneous transmission requirements. The user’s manual for the host product must clearly indicate the operation requirements and conditions that must be observed to ensure compliance with current FCC/ISEDC RF exposure guidelines. To comply with FCC/ISEDC regulations limiting both maximum RF output power and human exposure to RF radiation, use this module only with the included onboard antenna.
