无线模块使用方法

无线模块可以用于无线通信、传输数据等方面，具体使用方法如下：

1. 准备好所需的无线模块和相关配件（如电源、天线等）。

2. 将无线模块连接到电源，确保电源与模块匹配。

3. 安装天线，确保天线与无线模块匹配。

4. 配置无线模块，包括设置无线频率、无线通信协议等。

5. 把需要传输的数据通过串口、SPI等方式发送到无线模块。

6. 接收端收到数据后进行相应的处理，可以通过串口、SPI等方式接收数据。

使用无线模块时需要注意以下事项：

1. 使用无线模块时应严格遵守无线电管理条例，遵循频率规定，避免干扰其他无线设备。

2. 安全使用无线模块，避免电源过大、天线位置不当等导致的安全事故。

3. 根据不同的应用场景，选择不同的无线模块，保证通信距离、稳定性等关键指标的满足。

1产品概述

E47(2G4T12S）是一款基于SEMTECH公司SX1280射频芯片的无线串口模块（UART），透明传输方式，工作在2.4GHz频段，具有LORA、FLRC和GFSK三种调制解调技术，TTL电平输出，兼容3.3V与5V的IO口电压。LoRa直序扩频技术将带来更远的通讯距离，且具有功率频谱较宽，抗干扰能力强的优势。模块具有硬件FEC前向纠错算法，其编码效率较高，纠错能力强，在突发干扰的情况下，能主动纠正被干扰的数据包，大大提高可靠性和传输距离。模块具有数据加密和压缩功能。模块在空中传输的数据，具有随机性，通过严密的加解密算法，使得数据截获失去意义。而数据压缩功能有概率减小传输时间，减小受干扰的概率，提高可靠性和传输效率。E47(2G4T12S）系列产品为硬件平台，无法独立使用，用户需要进行二次开发。产品型号载波频率发射功率参考距离(PCB/IPX)封装形式天线形式E47(2G4T12S）2.4GHz12dBm3000m贴片IPX/PCB目录

1. 将测试用节点（CC2530）烧写coordiantor程序(测试可执行文件\SerialAppCoordinator.hex)：

2、将待测节点（mini2530）烧写Enddevice程序(测试可执行文件\SerialAppEndDevice.hex)：

3、将测试用节点（CC2530）通过串口线连接PC，打开串口调试助手发送数据，设置参考下图即可（发送区，不要勾选16进制）

4、A8安装serialDemo程序，可以把serialDemo.apk复制到SD卡里，通过SD卡安装该程序，也可以通过数据线一端插入A8的J8口，一端连接PC，通过360手机助手等安装该程序。serialDemo程序通过jni底层接收来自串口的数据，通过udp模式通过网络wifi发送出去，其中ip默认192.168.1.199，可以根据实际情况填写IP，务必保证A8连入的wifi与PC的IP在同一网段。

5、A8串口接收数据：打开A8连上wifi，然后打开serialDemo软件

6、PC端接收数据

7、

说明：

192.168.1.186为本地IP，不需要更改，serialDemo的IP与本地IP一致即可；

8001为设定端口，不需要更改。
