EdgeSense Southbound Service Development

Introduction

This guide will help you build an EdgeSense Southbound service.

You can develop WISE-Agent plugin (a.k.a Northbound plugin) by SRP-Plugin.

And your plugin (built with SRP-Plugin) also can be running as a Southbound service.

At first, please refer to below documenation to develop a plugin.

• How to Develop Customized Plugin Step by Step

After the completion of your plugin development, you will need EdgeSense Device SDK to pack your plugin as a Southbound service.

To accellerate the development of EdgeSense southbound service, you will need to install EdgeSense Device SDK.

This is very helpful to shorten the time for integratoin, to build a flexible and powerful EdgeSense device service in fastest and most stable way.

Run EdgeSense Southbound service

Requirement

To build and run Southbound Service, please setup below softwares:

• Compiler Tools
• MQTT Broker
• WISE-Agent

1. Compiler Tools

For Windows development,

• Please install Visual Studio 2008 or above. Visual Studio is available at official website.

For Ubuntu 16.04 development, please install below software,

$ sudo apt install autoconf autotools-dev libtool libmosquitto1 sqlite3 libxml2-dev libcurl4-openssl-dev libx11-dev libxtst-dev libxext-dev libmosquitto-dev libssl-dev

2. MQTT Broker

MQTT Broker For Windows

• download

MQTT Broker for Ubuntu 16.04

• download

$ sudo chmod +x MQTTBrokerSetup-1.0.5-Ubuntu_16.04-x86_64.run
$ sudo ./MQTTBrokerSetup-1.0.5-Ubuntu_16.04-x86_64.run

3. WISE-Agent

WISE-Agent for Windows

• Download from WISE-PaaS/EdgeSense Portal, Settings Page.

WISE-Agent for Ubuntu 16.04

• Ask support AE to get latest WISEAgent.

Download EdgeSense Device SDK

Download Agentlite for Windows development

git clone https://github.com/ADVANTECH-Corp/agentlite.git

Download Agentlite for Ubuntu 16.04 development

git clone -b Ubuntu-16.04 https://github.com/ADVANTECH-Corp/agentlite.git

Run EdgeSense device service on Windows

1. Copy HandlerSample.dll to agentlite\prebuilt\module folder.

When we download agentlite, it looks like this picture:

Copy HandlerSample.dll to agentlite\prebuilt\module folder.

2. Modify agentlite\prebuilt\module\module_config.xml

<ModuleNum>1</ModuleNum>
<ModuleName1>HandlerSample</ModuleName1>
<ModulePath1>\module\HandlerSample.dll</ModulePath1>
<ModuleEnable1>TRUE</ModuleEnable1>

3. Modify agentlite\prebuilt\agent_config.xml

<DeviceName>HandlerSample</DeviceName>
<DevID>HandlerSample</DevID>
<SN>HandlerSample</SN>
<DevType>Service</DevType>
<WorkDir></WorkDir>
<ServiceName>Agent_HandlerSample</ServiceName>

4. Run Southbound service.

cd agentlite\prebuilt
CAgent.exe -n  

Run EdgeSense device service on Ubuntu 16.04

1. Build SRP-Plugin and HandlerSample service

$ cd SRP-Plugin
$ sudo ./pre-install_ubuntu.sh
$ ./build-srpplugin.sh

2. After build is complete, HandlerSample service is generated in SRP-Plugin/Release/module folder.

$ ls -1 SRP-Plugin/Release/module/
HandlerSample.so
HandlerSample.so.0
HandlerSample.so.0.0.0
ModbusSample.so
ModbusSample.so.0
ModbusSample.so.0.0.0
module_config.xml

3. Copy HandlerSample to agentlite/prebuilt/module folder.

cp -af HandlerSample.so* agentlite/prebuilt/module

4. Modify agentlite/prebuilt/module/module_config.xml

<ModuleNum>1</ModuleNum>
<ModuleName1>HandlerSample</ModuleName1>
<ModulePath1>/module/HandlerSample.so</ModulePath1>
<ModuleEnable1>TRUE</ModuleEnable1>

5. Modify agentlite/prebuilt/agent_config.xml

<DeviceName>HandlerSample</DeviceName>
<DevID>HandlerSample</DevID>
<SN>HandlerSample</SN>
<DevType>Service</DevType>
<WorkDir></WorkDir>
<ServiceName>Agent_HandlerSample</ServiceName>

6. Run Southbound service.

$ cd agentlite/prebuilt
$ ./cagent -n

Then you will see HandlerSample is loaded.

$ ./cagent -n
HandlerLoader loaded
DllInitializer
DllFinalizer
DllInitializer
GeneralHandler loaded
 general> Initialize
DllInitializer
Load HandlerSample Successful

 HandlerSample> InitializeSADataSync_Initialize()

> HandlerSample StartAgent Initialized
Agent_HandlerSample no-service is start successfully!

Demo on WISE-PaaS/EdgeSense

In WISE-PaaS/EdgeSense , HandlerSample service is listed in Device Monitoring page.

In WISE-PaaS/EdgeSense, you can  read sensor data in Get/Set Sensor Data page.
