Sendero Middleware

Introduction

It's a middleware (ẁritten in Python3) between an ArtNet Server (like Sendero Server) and the Sendero-Wireless-Module. In addition to translating ArtNet to Sendero-Wireless-Protocol, this middleware is responsible for the device management, the control server and a set of streaming tests.

It offers the following execution modes:

• devserver: Starts a straming session with device management. Allows an extra parameter to send a simulated streaming among sin|flash|artnet.

• prodserver: Starts a streaming session with device management, control and keep-alive servers. Allows an extra parameter to send a simulated streaming.

Stream modes:

• sin: Streams a sin-controlled lighting pattern.

• flash: Streams a flash pattern in broadcast mode.

• artnet: Receives, adapts and redirects ArtNet packets.

Modules

• config: Stores all the configurable settings.

• streaming: Module responsible of the translation and redirection of Art-Net packets.

• utils: A set of utilitary methods for the whole app.

• devices: Device manager, is responsible for all the actions related to a wireless device. (Registering, Controlling, etc...)

• networking: Used to manage multicast mode. The frame information can be sent in 2 modes: broadcast|multicast. In broadcast mode, UDP broadcast IP is used (255.255.255.255) and all frame data is sent in just 1 packet. For artworks containing a lot of pixels, the size of the packet can be divided using multicast. This can be enabled in config.py.

Settings

All configurations are commented in the config.py module.
