MQTT server for Lambdaspace's members


What is MQTT?

MQTT is a light-weight Machine-2-Machine (M2M) messaging protocol based on the “publish-subscribe” architecture.

Usign Tech Ministry’s MQTT server.

MQTT servers are generally called brokers. In order to connect to Tech Ministry’s MQTT broker a member needs:

  • An MQTT client
  • A set of credentials (username, password)
  • The CA’s public key (since the communication is encrypted)

Obtaining credentials and CA’s public key

  • For the time being in order for someone to obtain a set of credentials, he has to request the from a member of the MQTT working group.
  • The CA’s public key can be obtain here.
  • Any MQTT client using MQTT protocol version 3.1.1 can be used.
  • Broker’s hostname and port can be obtain here

Tested MQTT clients:

Note: When implementing an MQTT client don’t forget to catch disconnects and try to reconnect automatically.

Each user can publish/subscribe to all topics under the member/userName topic.
