Complete Discovery Flow

Page({
  data: {
    devices: []
  },

  startScan() {
    my.onBluetoothDeviceFound((res) => {
      const newDevices = res.devices.filter(
        d => !this.data.devices.find(existing => existing.deviceId === d.deviceId)
      );

      if (newDevices.length > 0) {
        this.setData({
          devices: [...this.data.devices, ...newDevices]
        });
      }
    });

    my.startBluetoothDevicesDiscovery({
      allowDuplicatesKey: false,
      success: () => {
        this.setData({ scanning: true });
        // Stop after 10 seconds
        setTimeout(() => this.stopScan(), 10000);
      }
    });
  },

  stopScan() {
    my.stopBluetoothDevicesDiscovery();
    this.setData({ scanning: false });
  }
});
