Host Interfaces Network HTTP Client

Using the SpringCore device over HTTP

HTTP is the major client/server protocol of the Web.

The SpringCore device is a HTTP client that invokes a REST API from a HTTP server every time a tag or token is read. The script or program behind the REST API on the server may send a command to the reader in response.

HTTP is a nice feature to quickly set-up a demo, but has a few drawbacks:

  1. The communication channel between the reader and the server is not persistent, therefore the server can send a command to the reader only when a tag has just been read.
  2. Opening an HTTP channel for every event is costly in terms of CPU load and bandwidth, and the user may find that the reader is ‘too slow’.
  3. There is no security for HTTPS is not supported by the reader.

For any serial application, please consider using MQTT Client instead of HTTP.
