• Remotely configurable Beacons

IEEE802.15.4 (e.g.mesh network)

based back-end to configure

BLE beacon content

Use-case: Managed BLE Beacon Network • Locationing, broadcasting information and advertising

• Use IEEE802.15.4 mesh network as a backbone system to connect outside world

• Dynamically change the content of the beacons

Real World Implementation

• 6LoWPAN IEEE802.15.4 mesh network with managed BLE beacon realized using Open Source Contiki

1. Edge Router, Beaglebone Black + CC2531 USB dongle

– 6LBR Edge Router based on enhanced Contiki

• 6LBR is deployment-ready for industrial use-cases; no need to be a Contiki expert to get started.

• Webserver for configuration and visualization of nodes

– Standard NAT64 translate between IPv6 (6LoWPAN) and IPv4 for connection to standard Internet (IPv4)

2. Mesh Device, CC2650 SensorTag running Contiki

– Multiple apps running;

1. MQTT client, connect to cloud server and push sensor data.

2. Net UDP UART, use UART to send/receive data to/from any IP address

3. COAP server, exposing it’s resources (sensors etc), use SET & GET etc to interact

4. HTTP Web server, view resources using browser.

5. UDP 6lbr client, show network topology on 6LBR web sever

6. BLE ADV (beacons) packets sent out periodically,

configurable over COAP.

– Total: 105kB Flash, 18kB RAM on SensorTag

2. Interaction

1. Discovery

Use-case: Discover and interact 1. A smartphone application detects the precense of a device via it’s beacon

ID and want to send data to it

2. The smartphone application then sends the beacon ID to the network

backend via the Internet together with data

3. The backend authenticates the access rights of the user and validates the

changes

4. The data is then propagated out to the device via the Internet and the

IEEE802.15.4 mesh network to the device

Pros over connected Bluetooth® Smart

- The back-end server authenticates and monitor all transactions

- Device only have to contain one communication stack

Cons

- Device and smartphone needs Internet access

- Lower transfer bandwidth

TI

• Role Switching

Device is either in IEEE802.15.4

or Bluetooth® Smart Connected

Mode

• Use button to switch mode

– Single button interface to make it

Bluetooth® Smart connectable

Use-case: OTA Firmware update

• OTA firmware update over a multihop mesh can be slow and consumes a lot of power

• Installation and service of devices in the field is usually done using non-standard

dedicated expensive hardware, wire-connected or wireless

• An alternative is to upload it locally using a standard consumer device (e.g. a smartphone

or tablet) through Bluetooth® Smart

• The high datarate of Bluetooth® Smart will reduce the power consumption and no special

tools are needed. The update can potentially also be done by a local person (i.e. no need

for a trained technician)
