¶ MQTT Client
MQTT is the most widely used messaging protocol for the Internet of Things (IoT). With the MQTT client, you can connect the Divako network to another network to receive data or publish data to the outside world for the Divako network. This is a very powerful tool to listen to different types of networks, because we have
the ability to define what your payload looks like, and then we can use most of your data as if it were on our network.
¶ MQTT Publish
MQTT publish mode is for sending data to other servers that support MQTT stream.
¶ MQTT Subscribe
MQTT subscription mode is for listening and collecting data from other servers that support MQTT stream.
¶ Data Settings
Data settings gives possibility to define for Divako where is needed data in payloads.
If you notice that the MQTT Integration is receiving payloads but not creating a device under Divako, it could be due to incorrect mapping or missing data in the required fields.
¶ Required fields
- Topic - Can filter out topics what MQTT Client going to listen
- Payload Path - Where is RAW hex payload locating in payload.
- EUI Path - Path to device EUI
- Serial Path - Path to device Serial
- Type Path - Path to payload data type aka fPort
¶ Optional fields
- RSSI Path - Path to RSSI
- DR/SF Path - Path to Data Rate or Spreading Factor
- Gateway EUI Path - Path to Gateway EUI
- Device location Path - Path to location data where Divako can find Longitude and Latitude
- Gateway RX Info Path - Path to rxInfo
- Gateway location path insider rxInfo - Path to Gateway location
- Frequency Path - Path to Frequency data
¶ MQTT Client V2
MQTT Client V2 can only subscribe, but it includes significant stability enhancements that make MQTT Stream more reliable and compatible with the latest MQTT Servers. Additional reasons to adopt this new engine include its simplicity.
¶ Key Advantages
- Automatic Handling of Self-Signed Certificates: Eliminates the need for manual updates.
- Multiple Topic Listening: Reduces the need for multiple connections on a single server.
- Advanced Mappings: Incorporates more complex mappings and automatically detects many parameters.
- Data Rate Calculation: If the payload lacks a Data Rate (DR) but includes a Spreading Factor, the engine calculates the DR for you.
In version one, paths were defined using slashes
/, whereas in version two, path subparameters are separated by dots.
