请注意,本教程假设您使用的是 Linux PC。
这个项目建立在这个项目中开发的云基础设施之上。
1-您必须遵循以下步骤:
2-您必须安装 Git。如果没有安装 Git,可以在这里下载。
1- 打开终端并运行以下命令来设置网关:
> git clone -b experiment https://github.com/eclipse/paho.mqtt-sn.embedded-c
> cd paho.mqtt-sn.embedded-c/MQTTSNGateway
> make SENSORNET=udp6
> make install
> make clean
2-打开gateway.conf
文件并以这种方式编辑内容:

基本上,您必须配置 MQTT 部分(我们将与之交互的代理,在我的情况下它是一个localhost
并在1884
端口中运行)。
另一件重要的事情是您必须绑定 upd6 地址(fec0:affe::1/64
与您在 RIOT-OSREADME
文件中看到的用于 MQTT-SN 连接的地址相同)和端口(1885
是允许您从 RIOT 接收消息的端口实例)。
3- 要执行网关,请从安装 Paho 的目录打开终端并运行以下命令:
> ./MQTT-SNGateway
1- 安装 Mosquitto 代理。你可以在这里下载。
2- 现在,您需要配置网桥,以便 Mosquitto 代理可以创建到 AWS IoT 的连接。为此,您必须创建一个新mosquitto_bridge.conf
文件并在其中写入以下行:
# =================================================================
# Bridges to AWS IOT
# =================================================================
# AWS IoT endpoint
connection awsiot
address a6as4ru7uhh5u-ats.iot.us-east-1.amazonaws.com:8883
# Specifying which topics are bridged
# topic awsiot_to_localgateway in 1
# topic localgateway_to_awsiot out 1
# topic both_directions both 1
topic sensor/values both 1
# Setting protocol version explicitly
bridge_protocol_version mqttv311
bridge_insecure false
# Bridge connection name and MQTT client Id,
# enabling the connection automatically when the broker starts.
cleansession true
clientid bridgeawsiot
start_type automatic
notifications false
log_type all
# =================================================================
# Certificate based SSL/TLS support
# -----------------------------------------------------------------
#Path to the rootCA
bridge_cafile ./AWS-certs/rootCA.pem
# Path to the PEM encoded client certificate
bridge_certfile ./AWS-certs/fc278d0e63-certificate.pem.crt
# Path to the PEM encoded client private key
bridge_keyfile ./AWS-certs/fc278d0e63-private.pem.key
用您自己的端点替换此部分很重要:
在这里你必须插入你的证书的路径:
请记住,您已在此步骤中下载并保存了证书:
3- 要在端口上运行 Mosquitto 代理1884
,请从配置文件的根目录打开终端,然后执行以下命令:
> sudo mosquitto -c ./mosquitto_bridge.conf –p 1884
初步要求
您必须已安装:
