picogw-plugin-mqtt v0.0.2
This package is no longer necessary, because MQTT support is unified into PicoGW core system.
MQTT plugin for PicoGW
This is a MQTT plugin package of PicoGW, developed by Shigeru Owada@Sony CSL.
PicoGW MQTT plugin allows calls of PicoGW API through MQTT broker. However, because of its early development stage, it currently does not support authenticated access. Please understand that this plugin can increase vulnerablility of your network. We do not take any responsibility.
Installation
npm i -g picogw # Install Picogw
npm i -g picogw-plugin-mqtt #Install MQTT pluginRunning
picogwUninstallation
npm un -g picogw-plugin-mqtt
npm un -g picogwHow to use
Boot PicoGW with MQTT plugin and open the frontend http://localhost:8080/. The mqtt object shows up under /v1/. Right click on it and then left click the Settings button to open Settings dialog.
By default, the first combobox is 'false', which means the plugin is not connected to MQTT broker yet. The MQTT broker address is defaulted to mqtt://test.mosquitto.org, and MQTT Quality of Service is 1. Please change the broker address (which can start with mqtts://) and QoS as desired, change the first item to true and press Apply button at the right-bottom. The plugin should connect to the broker.
The plugin subscribes to the topic whose name is the MAC address of the running machine plus '-Req' (eg. '11:22:33:44:55:66-Req'. The MAC address PicoGW knows (including itself) is listed under /v1/admin/net. Please check the MAC address which corresponds to the IP address of the machine.
The MQTT API client sends request to the topic [MAC ADDRESS]-Req, and receives the result at the topic [MAC ADDRESS]. Like websocket API, MQTT plugin provides both procedure call (that immediately returns the payloaded reply) and subscription (that returns the reply when published.) Concrete client example is in test-tool.js.
Testing feature
This plugin has two unnecessary APIs for testing purpose. One is a dummy procedure call /v1/mqtt/testProcedure The other is a dummy topic that publishes every two seconds /v1/mqtt/testTopic. These two APIs are used in client example test-tool.js.
