Bluetooth low energy Device Roles

• A Bluetooth low energy device can operate in four profile roles:

– Peripheral • An advertiser that is connectable • Operates as a slave in a connection • Example: Heart Rate Sensor

– Central • Scans for advertisements and initiates connections • Operates as a master in connections. • Example: Smartphone

– Broadcaster • An advertiser that is non-connectable • Example: Temperature Sensor

– Observer • Scans for advertisements, but cannot initiate connections • Example: Temperature Display

10

Heart Rate Profile

Profiles and Services

• A Profile defines and describes

the use of Services necessary to

implement a given Application

• Bluetooth SIG adopted examples:

– Heart Rate Profile

• Heart Rate Service (HRS)

• Device Information Service (DIS)

– Proximity Profile

• Link Loss Service

• Immediate Alert Service

– Find Me Profile

• Immidiate Alert Service

Bluetooth low energy Q&A

Question Answer

Is dual mode Bluetooth

needed?

If you want to communicate with all devices on the market,

having backwards compatibility with Classic Bluetooth devices

- you’ll need dual-mode

Is it possible to upgrade the

firmware Over The Air?

Yes, we have several solutions to do so, including direct

update from a Smartphone/Tablet.

Can CC2540/41 use coin cell

batteries and how long would

the battery operate?

Yes, it can use coin cell. Depending on application, you can get

many years of lifetime (please note a coin cell could be limited

by self discharge rather than capacity)

Can I add BLE to my existing

product?

Using CC2540/41 as a network processor, TI supports any

micro on the market.

Do I have to pay any royalties

to Apple? No, BLE is the only solution for accessories to avoid MFI cost.

Is BLE supported by Android

too?

For the moment (Q1/13) no official support from Google. Some

devices from Samsung and Motorola have their own BLE

support, which would be solved by writing an individual app per

device.

Initial design considerations

Question Why is it important?

What datarate will your

application require?

Our BLE stack supports 8KB per second. Note that the

throughput is dependent on the peer device too.

What volume do you expect

on a yearly basis?

For Low volumes (10-100KU) we would recommend using

a module vendor. This would save you cost and time for

design and certification.

For high volumes we recommend using our reference

design - QFN chip on Board

Does your application need

to connect to a PC?

If yes, our CC2540 SoC has USB support for direct

connection to PC.

Will iOS be part of the eco

system?

TI can provide you source code examples to get you started

for free.

Would you need a officially

adapted profile, or would

you make you own?

We support all officially adopted profiles in addition to our

own proprietary profiles (like the Sensor Tag) which you can

use as a starting point.

• Direct control from Phone/Tablet

• Lowest cost connectivity

• Lowest power connectivity

Why TI BLE for Lighting?

• 125°C roadmap

Lighting Bluetooth Smart for Lighting already happening

Direct control over light from phone/tablet

53

• Control individual or a group of lights

– Control intensity and color combinations

– Set timing triggered events, smooth wake up to a slowely increasing

light or dim the lights slowely when going to bed

– Proximity based, turn lights on/off based on proximity to phone to

lower energy usage

• Enhance your product with a Software Development Kit (SDK)

– Allow other app developers interact with your light

Use light as notifier

54

• Let your light interact with your social life

– Blink or change color upon notifications: Message, Incomming call,

New Mail, Facebook Alert etc.

– Different notifications can have different blink patterns or colors

BLE Light Demo using TI BLE Multitool

55

• Individual intensity control over 4 LEDs (Red, Green, Blue and

White)

• Powered by USB micro

• TI BLE Multitool for iOS allows for control of 10+ lights

• Schematics, layout and embedded FW available upon request

CC2540T Worlds first 125ºC qualified SoC for Bluetooth Smart applications

• LED lights are usually designed to keep the

LED die junction below 125ºC(1)

• Consumer graded parts might not be

sufficient if used in close proximity to LEDs

• By using CC2540T, graded up to 125ºC, RF

and SoC performance is ensured for the

entire temperature range of the LED light

• Based on same technology as CC2530

shipped in millions into replacement light

bulbs for years

• CC2540T is highly suited for other industrial

applications as well

Bluetooth Smart Broadcaster

SW example for broadcast only applications on CC2541 and CC2543

Low Power RF

57

Why Bluetooth Smart Broadcaster?

58

• Reducing the power consumption

– A non-connectable Broadcaster eliminates the need for RX and the overall

radio duty-cycle is lowered

– A simple Broadcaster can be implemented directly on the Radio, by-passing

the need for full BLE Stack - simpler SW removes power consumption

related to heavy stack processing

• Can be implemented on CC2543 for lower cost and smaller size

– Smallest TI SoC implementation for a Bluetooth Smart device

• CC2541 soft bootloader allows switching between

– Lower powered Bluetooth Smart SW

– Standard BLE stack for connection events

Bluetooth Smart Broadcaster - examples

59

• Simplify a weather station

for quicker time to

market and lower cost

solution using CC2543

• Add flexibility and

lower power to products

• Use CC2541 to boot between:

• Connection based for OAD, Security and Bi-

Directionality

• Broadcast for more displays and lower power ++

• Proximity based

advertisment for retail/

directed campaigns

How does the Broadcast example work

60

• Simple broadcaster application example assimilating the BLE

ADV_NONCONN_IND (Bluetooth core spec 4.0) advertizing packets.

• The application will transmit an advertizing packet at a given interval.

For each event the same packet will be transmitted to all active

broadcast channels back2back.

• The application will enter PM2 between each advertizing event.

• Which channels that are active can easily be selected

How does the Broadcast example work

61

• advInterval is adjustable in the range 100 ms to 10.24 s.

• advDelay is added in addition (pseudo-random 0-10 ms).

Broadcast example Power Consumption

Measured on CC2541 Keyfob:
