The Web Gateway (WG) communicates with the Connection Layer (CL) using the osvgateway protocol over a websocket. The WG initiates the websocket when it boots, and initiates any messages.

Commands are case-sensitive. This is version 1 of the protocol

A typical conversation would go like this, more details below:

From To Message
WG CL STOCK:<MAC address>:<hopper>
CL WG STOCK:<hopper>:<status>
WG CL VEND:<vend id>:<MAC address>:<hopper>
CL WG VEND:<vend id>:ACK
CL WG VEND:<vend id>:<status>:<reason>
