Hi みやかわ,

We have developed it and testing now.
I think, it will release in one or two week.

When it release, I will tell you in this thread.

Hi みやかわ,

obniz sdk version 1.9.5 released and it includes BLE notifications.
The document is here

You can use like this.
Don't forget to set CCCD descriptor (0x2902).

var characteristic = new obniz.ble.characteristic({
  uuid: 'FFF1',
  data: [0x0e, 0x00],
  properties : ["read","write","notify"],  // add notify properties
  descriptors: [
    {
      uuid: '2902', //CCCD
      data: [0x00, 0x00],  //2byte
    }, 
  ],
});

var service = new obniz.ble.service({
  uuid: 'FFF0',
  characteristics: [characteristic],
});
obniz.ble.peripheral.addService(service);


// after central connected
characteristic.notify();

If you want to notify when someone change value,

characteristic.onwritefromremote = function(address, newvalue){
   characteristic.notify();
}
