Bluetooth Low Energy (BLE) – Applications

Building automation

Bluetooth low energy (BLE) technology is ideal for building automation applications. With smartphone interoperability and consumer convenience, Bluetooth low energy has gained tremendous traction in the home automation market. Discover more about TI's Bluetooth low energy solutions to differentiate your building automation designs.

Smart Door Locks

With Bluetooth® low energy (BLE) technology door locks can be controlled from a smartphone or tablet. Users can receive alerts if the front door is left unlocked and even create personalized schedules to fit a busy lifestyle. Choosing Bluetooth low energy technology is easy based on the ultra-low power consumption which enables longer battery lifetime and with a standard's based protocol there is always interoperability with smartphones. Bluetooth low energy supports low power continuous connectivity and Wi-Fi can also be included for cloud connectivity.

Key benefits of TI's Bluetooth low energy for smart locks:   

  • Range   
  • RF performance   
  • 1uA sleep current with full memory retention   
  • Enhanced security with fully certified Bluetooth 4.2 software stack   
  • Small package size

Beacons

As Bluetooth low energy (Bluetooth low energy) advances beyond personal electronic applications, beacon deployments are increasing across many other industries. Imagine a phone application with directions to navigate a large department store or retail discounts when walking through the product aisle. There are endless use cases for beacons and Bluetooth low energy technology is ideal for these applications based on low active current consumption which provides very long battery lifetime. The Bluetooth 4.2 specification also enables richer data to be transmitted over a beacon with the Data Length Extension feature and there is increased privacy to ensure devices aren't being tracked. To learn more about using TI's Bluetooth low energy products in a beacon design check out the additional information below.

Key benefits of TI's Bluetooth low energy for beacons:   

  • Supports iBeacon and Eddystone formats   
  • Low TX/RX and standby current   
  • High degree of freedom to set advertising parameters   
  • Small package size   
  • Supports Bluetooth 4.2 Data Length Extension & enhanced privacy

Automotive

Bluetooth low energy (BLE) is an emerging technology within automotive and can be used in many applications such as in car access, car sharing, piloted parking and cable replacement systems allowing a new level of innovation among connected devices such as smartphones, smartwatches etc.

Car Access

Benefits of Bluetooth low energy in a Passive Entry Passive Start (PEPS) system

In addition to Interoperability with smartphones and wearables, Bluetooth low energy technology could be used to grant you access to your vehicle. Within car access systems, Passive Entry Passive Start (PEPS) solution offers you the possibility to lock/unlock your car and start/stop it without any manual interaction with your key fob. TI's CC2541-Q1 enables Bluetooth low energy connectivity from The Body Control Module (BCM) to multiple access devices such as key fob or a smartphone. Key benefits of TI's CC2541-Q1:
