BLE TI SensorTag CC2650

I'm trying to get the Button Presses from the Sensor via the SensorTag BLE script provided in the LM.
I'm getting Data like Humidity etc, but no matter what i tried the button values don't update on button press.

Code:

return {
  manufacturer = 'TI',
  description = 'SensorTag',
  default_name = 'SensorTag',
  version = 2,
  objects = {
    {
      id = 'temp',
      name = 'Temperature',
      datatype = dt.temperature
    },
    {
      id = 'hum',
      name = 'Humidity',
      datatype = dt.scale
    },
    {
      id = 'button1',
      name = 'Button 1',
      datatype = dt.switch
    },
    {
      id = 'button2',
      name = 'Button 2',
      datatype = dt.switch
    }
  },
  init = function(device)
    local objects = device.objects

    if not objects.button1 and not objects.button2 then
      device.profile.step = nil
    end

    if not objects.temp and not objects.hum then
      device.profile.read = nil
    end
  end,
  setbutton = function(device, button, value)
    local key = 'button' .. button

    if device[ key ] ~= value then
      device.writeobject(key, value)
      device[ key ] = value
    end
  end,
  step = function(device)
    local sock, res, data, err, setbutton

    sock = device.sock
    setbutton = device.profile.setbutton

    if not sock then
      sock = ble.sock()
      ble.settimeout(sock, 1)

      -- try connecting
      res = ble.connect(sock, device.mac)
      if not res then
        ble.close(sock)
        device.setactive(false)
        os.sleep(5)
        return
      end

      -- enable button notification
      ble.sockwritecmd(sock, 0x60, 1, 0)
      device.sock = sock

      setbutton(device, 1, false)
      setbutton(device, 2, false)
    end

    res, data = ble.sockreadnotify(sock, 1)
    -- read ok
    if res then
      data = data:byte(1)

      setbutton(device, 1, bit.band(data, 1) == 1)
      setbutton(device, 2, bit.band(data, 2) == 2)

      device.setactive(true)
    -- timeout or disconnect
    else
      res, err = ble.check(sock)

      -- disconnect
      if not res or err ~= 0 then
        ble.close(sock)
        device.sock = nil
      end
    end
  end,
  read = function(device)
    local sock, res, status, values, rssi

    if device.profile.step then
      sock = device.sock
      res = sock
    else
      sock = ble.sock()
      ble.settimeout(sock, 1)
      res = ble.connect(sock, device.mac)
    end

    -- connect ok, enable sensor, wait for conversion to finish, read the result
    if res then
      ble.sockwritecmd(sock, 0x3C, 1)
      os.sleep(0.1)
      res = ble.sockreadhnd(sock, 0x38)

      -- read ok
      if res then
        status = true
        values = {}

        rssi = ble.getrssi(device.mac)

        -- convert temperature
        tmp = bit.bor(bit.lshift(res:byte(2), 8), res:byte(1))
        tmp = -46.85 + 175.72 / 65536 * tmp;
        values.temp = math.floor(tmp * 10) / 10

        -- convert humidity
        tmp = bit.bor(bit.lshift(res:byte(4), 8), res:byte(3))
        tmp = -6.0 + 125.0 / 65536 * bit.band(tmp, 0xFFFC)
        values.hum = math.floor(tmp + 0.5)
      end

      -- disable sensor
      ble.sockwritecmd(sock, 0x3C, 0)
    end

    if not device.profile.step then
      ble.close(sock)
    end

    return status, values, rssi
  end
}

Might be bug somewhere, BLE has not been updated for some time. What is your use case for BLE? We are going to have ZigBee support in LM soon if you need wireless buttons/sensors.

Might be bug somewhere, BLE has not been updated for some time. What is your use case for BLE? We are going to have ZigBee support in LM soon if you need wireless buttons/sensors.

The main use case for BLE would be to detect via magnetic key (which this sensor is capable of) if the door to a server room is open or closed.

Is there an ETA on ZigBee support?

ZigBee is still in development. If you want to test then we can provide a USB dongle for LM. ZigBee door/window sensors are not supported yet but will be added soon.
