Reversing Orthoplay

Tested on OD-11 running V0.9.11

Endpoints

Communication to the OD-11 goes through Websockets. The OD-11 is running AutobahnPython 0.5.14 twice:

• PROD: http://od-11.local/ws
• DEV: http://od-11.local:8081

##Initiating communication To start communicating with the device, send the global_join message along with the protocol version you are going to use. At the time of writing this, 0.4 seems to be the newest.

The message will look like this: {"protocol_major_version":0,"protocol_minor_version":4,"action":"global_join"}

##Registering/configuring your remote Next you will need to register your remote with the following message: {"color_index":0,"name":"guest","realtime_data":true,"uid":"YOUR_REMOTE_UID","action":"group_join"}

In the js implementation, a unique ID for the remote is generated with the following code

var uid = "uid-" + Math.floor(1e8 * Math.random());

##Staying Connected In order to stay connected, it is required to send a ping with a timestamp every once in a while (The web client does this every 5 seconds)

var createPing = function() {
	return {
		value: (new Date).getTime() % 1e6,
		action:"speaker_ping"
	}
}

The ping message will look like this {"value":913577,"action":"speaker_ping"}

###Changing the Volume You can change the volume of your speaker group by sending the group_change_volume message along with the amount by which the volume should change

{"amount":-1,"action":"group_change_volume"}
