Custom Update Logic

To convert specific configuration needs you can define JavaScript functions that are called during the widget usage.

Writer Function

This JavaScript function is called each time a characteristic must be written. In this way, you can implement your custom write login, for instance by transforming the value to write, or by splitting it among multiple calls.

var bleCustomWrite = function(device, characteristic, value, widget) {
  return new Promise((resolve, reject) => {
     console.log(device);
     console.log(characteristic);
     console.log(value);
     resolve();
  });
};

See the Writer Function property on each characteristic. 

Update Callback

This JavaScript function is called after the Update button is pressed, so you can implement you custom post-update logic, for instance by calling an external service API, or by setting another characteristic to reboot the device or similar.

var bleCustomUpdate = function(device, context, widget) {
  return new Promise((resolve, reject) => {
     console.log("UPDATED");
     console.log(device);
     resolve();
  });
};

See the Update Callback property on the widget.

Configuration
