1 General Script Demo

1.1 Address Operation:Write/Read data from address A to B

Depend on diffferent format of data.V-Box use different script functions.
for example. addr_setshort(addr,num) Function: Write 16-bit signed decimal address
addr_getshort(addr) Function:Read 16-bit signed decimal address
addr_getword(string addr)Function: Read 16-bit unsigned decimal address
More script function are in the second section of  “V-BOX Script Interface Manual”

1.2 Arithmetic

1.3 Set 100 to D0--D19

1.4 Short message

When the alarm condition is reached: temp1 > 5 & temp2 >10 & temp3 < 20(lasts more than 5 seconds) , then send an "alarm trigger" sms. 

When the alarm condition is released，then send an "alarm release" sms.

Script is as below:

1.5 Telegram notification

This example shows how to use the Bot API to send message into Telegram group or channel. When monitoring bit "@HDX" changes, it will trigger and send the message. Please replace with your own Token and chat id.

2 V-Box connect with third part server

V-Box have two mode.One is for V-Net,User need to use WECON server to store data.We call this V-NET platform.

1.Europe server:eu.v-box.net 

2.Asean server:asean.v-box.net

Second is for OpenCloud mode.It means V-Box data will transfer to third part server and do not want to store data to WECON server.We call OpenCloud paltform

OpenCloud platform is used in configuring the script.Then V-Box can connect with third part server.

Both mode can support script  to connect with third part server.the difference:

1.If you want to store in WECON server ,please use V-NET.

2.If your server requires SSL certificate to log in,please use OpenCloud.Because only OpenCloud platform can support to upload certificate

2.1 V-Box connect with customer server:grouprobotinfo.com

This demo does not use SSL certification. Script is as below

2.2 V-Box connect with Azure platform

In this demo,V-Box connects with Azure by SSL certification.

2.3 How to configure the Huawei platform?（✎Note: Huawei IOT DA function is only in China area.If you want this function,you need to use chinese mobile to register）

1.Register a account: https://www.huaweicloud.com/intl/en-us/s/JUlPVERNJQ

2.log in the Huawei IOTDA

https://console.huaweicloud.com/iotdm/?region=cn-north-4&locale=en-us#/dm-portal/home

3.Create product

4.Product name,manufacturer,device type and industry,set according to your own needs.

Protocol: MQTT

Data Type: JSON

After finishing configuration,please click "OK"

5.Device

After product register,continue to configure "individual register".Click "Device"-->"individual register"

Notes for registering device:

Product: Previous product registration.

Node ID, Device Name: set according to your own needs.

Secret: need to be configured, will be used when connecting later

After configuration, click OK to generate a device ID and password, which will be used for device access later.

6. Connection authentication (use MQTT.fx tool to access the IoT platform)

(1)Open mqttClientIdGenerator tool Java(TM) Platform SE binary

Download

(2)Fill in the device ID and secret (deviceid and secret generated when registering the device) to generate connection message

Client ID, user name, password

(3) Download certificate file"North-Beijing4"

https://support.huaweicloud.com/en-us/devg-iothub/iot_02_1004.html

7.Run MQTTfx tool to connect with Huawei

Download link: http://mqttfx.jensd.de/index.php/download

(1)Click on the setting ICON

(2)Fill in IIOT MQTT device access address, and configure authentication parameters.
First: It is the server and port connected to Huawei IOT, which can be viewed through the overview of the interface.

Domain name:iot-mqtts.cn-north-4.myhuaweicloud.com

Port: 8883

Client ID: check step 6

(3)Upload SSL certificate file,check step 6

Select folder java-->DigiCertGlobalRootCA.crt.pem and click OK or apply button

(4)Connect and test publish and subscribe

Huawei publish topic format: $oc/devices/{device_id}/sys/properties/report

Huawei subscribe topic format: $oc/devices/{device_id}/sys/commands/#

(5).How to configure to view the received data format intuitively, multiple products (Huawei) are required to configure the model. The specific steps are as follows:
①Select the corresponding product from Huawei products to view

②Custom model: used to display the service ID name of the configuration report.

③Add property, ID of monitoring point, and data format:

④After the configuration is complete, check the received data on the device

2.4 V-Box connect with Huawei platform

In this demo,V-Box connects with Huawei by SSL certification.

1.Create a project access for Huawei IOT

2.configure MQTT configuration

3.Create a script with the demo as below.

 Script is as below

4.Download project access into V-Box to test in debug page 

2.5 V-Box connect with AWS platform

Log in AWS

Login aws account and click“Connect an IoT device”

Create policy

Click “Secure”--->“Policies”--->“Create policy”--->Click “Create”

Name the policy--->Click “JSON”--->Copy the following content--->Click “Create”

1. Create things

Click “Manage”--->“Things”--->“Create things”--->“Create single thing”

Name the thing--->Click “Next”

Select the way to create certificate

Select policy

1. Test with MQTT.fx tool

Click “View Setting” to get the “Broker Adress”

Create one connection in MQTT.fx tool, set broker port as 8883.

Upload the CA File, Client Certificate File, Client Key File

Publish message to topic “TEST”

Click”Test”--->”MQTT test client”--->”Subscrible to a topic”, to get message publish from MQTT.fx tool.

And we can also send message form AWS platform to MQTT.fx tool.

1. Configurate in CloudTool

Copy the same setting in MQTT.fx to MQTT configuration

 Add a lua script and copy the lua demo into it.

sprint = print

    if g_mq then

        g_mq:on("message", mymqtt_msg_callback) -- Register to receive message callbacks

        sprint("mqtt init success")

    else

        sprint("mqtt init failed:", err)

    end

end

-- Connect to MQTT server

function mymqtt_connect()

    sprint("mqtt connecting...")

    local stat, err = g_mq:connect(MQTT_CFG,MQTT_LWT, MQTT_CART)

    if stat == nil then

        sprint("mqtt connect failed:", err)

        return

    else

        sprint("mqtt connected")

    end

    g_mq:subscribe(TEST, 0)

end

-- Receive MQTT message callback function

function mymqtt_msg_callback(topic, msg)

    print("topic:",topic)

    print("revdata:",msg)

    local revData = json.decode(msg)

    print (revData)

 if topic == Subscribe_RE_TOPIC1 then --Process topic information subscribed from the cloud

if string.match(topic,Subscribe_RE_TOPIC1) then

    --if revData ~= nil then

        for k,v in pairs (revData) do

            print("printing revdata after kv here")

            print (k,v)

        end

        print ("current state is",fanstate)

    --end

end

end

end

--Get real-time data

    local jdata = {}

    local addr = bns_get_alldata()

    print(json.encode(addr))

    for i,v in pairs(addr) do

        if v[2] == 1 then

           jdata[v[3]] = v[4]

        end

    end

    return jdata

end

--send data

function send_Data()

    local pub_data =

    {

}

sprint(json.encode(pub_data))

print("..........",pub_RE_TOPIC)

    return g_mq:publish(pub_RE_TOPIC, json.encode(pub_data), 0, 0)
