LoRa模块的ID [英] IDs for LoRa modules

问题描述

我使用两个SX1278 LoRa Ra-02模块进行通信.我不知道如何为这两个模块设置ID以拒绝与其他以相同频率工作的LoRa模块的干扰.

I use two SX1278 LoRa Ra-02 modules for communication. I wonder how I can set IDs for these two modules to deny an interference with other LoRa modules which work at the same frequency.

我的意思是，有没有一种类似于NRF24l01通信的管道地址的解决方案. 提前感谢.

I mean, is there a solution similar to pipe addresses of NRF24l01 communication. Thanks in advance.

推荐答案

加密是阻止对您的通信进行监听的答案.这可以是基本的 XOR加密，也可以是

Encryption is the answer to blocking snooping on your communication. This can be a basic XOR encryption, a Caesar cipher or even better rsa.

对于唯一ID问题:有多种解决方案可以解决此问题，它在很大程度上取决于您所使用的特定微控制器.在 arduino.stackexchange.com 上提供了一种解决方案.

For the unique ID problem: there are several solutions to this problem and it highly depends on the specific microcontroller you are using. A solution was offered on arduino.stackexchange.com.

例如，ESP8266有一个唯一的ID，可通过以下代码访问:ESP.getChipId().

For example the ESP8266 has a unique ID accessible through this piece of code: ESP.getChipId().

使用外部硬件的另一种选择是Maxim Integrated的 DS2401 .这是可通过单线接口访问的Silicon Serial Number芯片.

Another option which uses external hardware would be the DS2401 from Maxim Integrated. This is a Silicon Serial Number chip accessible trough a one-wire interface.
