MQTT protocol

MQTT is a lightweight publish/subscribe messaging protocol which probably makes it the most suitable for IoT devices Learn more about MQTT.
iotBind platform integrates with MQTT.one services to publish messages to Your devices by Your mqtt.one account.
what you need:
1. Pro iotBind Account To activate the MQTT feature
2. Registration  in MQTT.one (MQTT Service) to get and use the Broker and Topic Data  

To generate a API key for device, click on the key icon After adding the device And Click on the refresh icon To generate a new key Any time.  

After registration in MQTT.one, Add topics you need to use, and back to account in iotBind.
comin main menu Click on "MQTT Service" enter you mqtt.one email and password and Click "link" button,
After successful linking Then you'll see all your Broker and topic data  

Now your account is ready to publish (messages) and subscribe (topic) by mqtt protocol

  

connect the sensors with iotBind by MQTT protocol:
- Broker Domian: Same Broker Domian in your MQTT.one account
- Port: Same Port in your MQTT.one account
- User : Same User in your MQTT.one account
- Password: Same Password in your MQTT.one account
- Client ID: iotbind-XXXXXXXXX"

Important!

replace XXXXXXXX with device UniqueID"  

publish data from sensors devices or application to iotBind platform:
After link your account with MQTT.one you will see the iotbind/sensors/ Topics where you can publish data message to iotBind

publish sensor data update from iotBind to any subscribes:
iotBind paltform can use any topic has permission to publishing a message by your MQTT.one account to Your Any subscribes that subscribe in the same topic After any update of the sensor data
if you need send mqtt data message After any update of the sensor data go to Sensors page and in the sensor Click in "edit" icon to show the device Setting and enable the "MQTT" publish messages feature and Select the topic you want the iotBind platform to publish messages to 

 "You can manage your list topics from your MQTT.one account"

  

Sending and receiving data messages format:

Text Message format: json  

ParameterValueDescription
uidUniqueIDDevice UniqueIDAlways use it When you want to send an update or get data
keyEncrypted keyDevice API secret keyAlways use it When you want to send an update or get data
cmdOne of these:"get""ping"only use one of these commands when you send message to iotbind"get" If you need get all device data frome iotBind platform"ping" If you need send ping Command to iotBind platform to learn that the device is connectedNote: When the device is connected by MQTT protocol, the connection status will be updated directly by server
data1Text or numbersUse it only for update data1
data2Text or numbersUse it only for update data2
data3Text or numbersUse it only for update data3

Examples:
After setup your device to contact the MQTT Broker and set publish to sensors Topics in iotBind Platform After any update , For Example:
if you need to send the update data by publish MQTT data message to iotBind platform, you need to send a txt json message to the special iotbind/sensor/ topic show in your iotBind account>MQTT Service like:

json
{
    "uid":"Device UniqueID",
    "key":"Device API secret key",
    "data1":"Anything",
    "data2":"Anything",
    "data3":"Anything"
}

* data1,data2,data3 is an any data you need to update

  

if you need to get Sensor data by publish MQTT message to iotBind platform, you need to send a txt json massege to the special iotbind/sensor/ topic show in your iotBind account>MQTT Service like:

json
{
     "uid":"Device UniqueID",
     "key":"Device API secret key",
     "cmd":"get"
}

iotBind platform publish a json data message to the same topic set on the sensor Edit page like:

json
{
    "uid":"UniqueID",
    "name":"DeviceName",
    "data1":"Anything",
    "data2":"Anything",
    "data3":"Anything"
}

If you want send ping Command to iotBind platform to learn that the device is connected by publish MQTT message to iotBind platform, you need to send a txt json massege to the special iotbind/sensor/ topic show in your iotBind account>MQTT Service like:  

json
{
     "uid":"Device UniqueID",
     "key":"Device API secret key",
     "cmd":"ping"
}

Note: When the device is connected by MQTT protocol, the connection status will be updated directly by server
