YIO is providing several API Services. To find out more about the different APIs follow the documentation beneth.

YIO Config API
YIO Dock API
YIO Remote API

The configuration is stored in config.json on the boot partition of the SD card.

The configuration class has the following methods:

config.read gives a JSON object. You can also access specific keys within this object: config.read.settings.darkmode for example.

config.write needs a JSON object to write. Example: config.write = newconfig; Please note, that this has to be the full configuration. If you want to change part of a config, do the following:

  var tmp = config.read;
  tmp.settings.darmkmode = false;
  config.write = tmp;

config.readConfig(<path to config file>) reads the config file from a file.

config.writeConfig() saves the config to the config file.

From C++ side, you can access the same methods:

• include the header file:

  #include "config.h
  

• call a function

  Config::getInstance()->read();
  

There's a websocket based API for communicating with the dock, running on port 946 ws://<IP>:946. The API is used to configure the dock, let it know the remote needs charging and for sending / receiving infrared signals.
Messages are sent in JSON format.

When a client connects, the remote sends a JSON message:

  {
    "type":"auth_required"
  }

The client needs to respond with:

  {
    "type":"auth",
    "token": "<token>"
  }

If you don't provide a token or the token is invalid, you get an error message:

  {
    "type":"auth",
    "message": "Invalid token"
  }

or

  {
    "type":"auth",
    "message": "Token needed"
  }

Default authentication token is "0"

  {
    "type":"auth",
    "token": "0"
  }

After successful authentication the client is flagged to be able to communicate with the API.

Configure dock friendly name:

  {
    "type":"dock",
    "command":"set_friendly_name",
    "friendly_name":"<Preffered Name>"
  }

Configure dock LED brightness:

  {
    "type":"dock",
    "command":"led_brightness_start",
    "brightness":100
  }

Stop LED animation:

  {
    "type":"dock",
    "command":"led_brightness_stop"
  }

Receive IR Signals:

  {
    "type":"dock",
    "command":"ir_receive_on"
  }

Stop receiving IR Signals:

  {
    "type":"dock",
    "command":"ir_receive_off"
  }

Send IR Signals:

  {
    "type":"dock",
    "command":"ir_send",
    "code":""
  }

  The code can either be comma seperated RAW signals or PRONTO Hex.

Reset dock configuration do default and reboot:

  {
    "type":"dock",
    "command":"reset"
  }

Inform the dock that the remote battery is low and needs charging (for LED indication)

  {
    "type":"dock",
    "command":"remote_lowbattery"
  }

Inform the dock that the remote battery is charged.

  {
    "type":"dock",
    "command":"remote_charged"
  }

There's a WebSocket based API for communicating with the remote, running on port 946(YIO). Mainly used by the web configurator tool and the YIO Dock.
See YIO WebSocket API for more information.

The API automatically starts on power up and is always running in the background. The API is stopped, before wifi is turned off and started, after wifi is turned on.
Messages are sent in JSON format.

You can access the API from the QML side:

  api.start();

or from C++ side:

• include the header file:

  #include "yioapi.h
  

• call a function:

  YioAPI::getInstance()->start();
  

When a client connects, the remote sends a JSON message:

  {
    "type":"auth_required"
  }

The client needs to respond with:

  {
    "type":"auth",
    "token": "<token>"
  }

If you don't provide a token or the token is invalid, you get an error message:

  {
    "type":"auth",
    "message": "Invalid token"
  }

or

  {
    "type":"auth",
    "message": "Token needed"
  }

After successful authentication the client is flagged to be able to communicate with the API.

When a message arrives from a flagged client, it gets emitted via the messageReceived signal. You can connect to this signal from QML or C++ to further process the message.

You can send messages to all authenticated clients with the sendMessage(QString msg) method. The message should be stringified JSON.
