Supported protocols

• MQTT C client
• MQTT client for Java™
• MQTT client for Android
• MQTT client for iOS

MQTT is a lightweight network protocol that is used for publish/subscribe messaging between devices. MQTT is ideal for use in constrained environments or low-bandwidth networks with limited processing capabilities, small memory capacities, and high latency.

• MQTT client for JavaScript

A WebSocket is similar to a TCP socket. The key difference is that a WebSocket provides MQTT support for web applications that run in a web browser. For more information about Websockets, see Websockets.

• IBM IoT MessageSight JMS client
• IBM IoT MessageSight JMS resource adapter

You might want to use JMS if you want the ability to develop and use Java EE applications. Additionally, you might want to use JMS if you have personnel with this skill, or if you want to use message browsing and message selection.

You can use protocol plug-ins to add industry-specific messaging protocols to IBM IoT MessageSight in a controlled way that does not compromise the security of the server environment. The protocol plug-in can also support legacy sensors that are not able to change to MQTT. You can write your own protocol plug-ins to use withIBM IoT MessageSight by using the IBM IoT MessageSight protocol plug-in SDK.
