Live Communication

With Live Communication, the Lisa makes a persistent connection to the Live Communication URL.
When this connection is broken, the Lisa will try to reconnect. The connection can be used to

·

change settings

·

start actions

·

retrieve status and diagnostic information*

This is done by sending commands to and receiving the responses from the Lisa.

*Sending self-test commands is not recommended.

For Live Communication to work, both the Lisa and an end-user/client application need to connect to a
platform that supports Live Communication. This platform can be the Streamit Live Communication
Gateway.

You can also develop your own platform to handle Live Communication. See

Your own custom-built

for more information

15.1

The Streamit Live Communication Gateway

The Streamit Live Communication Gateway is a platform to which the Lisa and end-customer/client
applications can connect for Live Communication.

You can build your own applications for 'live' interaction with Lisa devices anywhere in the world, using
the API of the Streamit Live Communication Gateway.

To use the fully documented API of the Streamit Live Communication Gateway a subscription is
required, please contact

[email protected]

for more information.

Streamit does not provide an end-user/client application to use Live Communication. The wide range of
use cases for Live Communication and the vast number of potential target platforms (from PCs to all
types and versions of smartphone operating systems) makes this impossible.

A minimum working example of an end-user/client application for the Streamit Live Communication
Gateway is available for testing and reference. This simple example application is provided free of
charge and 'as-is'.

15.2

Enable Live Communication on the Lisa

To use Live Communication with the Lisa, the following is needed:

·

The Live Communication URL should point to a platform that supports Live Communication

·

The Live Communication feature should be enabled on the Lisa (selective use of this feature can help
to prevent overload on a platform)

These setting can be enabled via the configuration and via a
