The advent of Bluetooth Low Energy (BLE) has revolutionized the concept of the Internet of Things (IoT) and has helped take it from concept to commercial reality. The biggest reason for the proliferation of BLE has been its presence in smartphones, tablets and off-late, laptops too.
Figure 3 shows the implementation of the Smart Light Controller using PSoC 4 BLE.

This device not only implements all three of the above mentioned system features (sensor interface, light control unit, BLE communication), but also makes the implementation easy by providing the BLE Component, that creates BLE GAP Central and GAP Peripheral products in minutes. Cypress application note AN91162 provides information on implementing BLE-compatible Profiles for such custom applications that are not supported by the BLE Standard-Adopted Profiles from the Bluetooth SIG.

 

Conclusion

BLE has played a key role in making the IoT successful and has become the de-facto standard for IoT applications. It is not only used for wearable applications but is also proving to be a useful standard for home automation applications. BLE’s current limitations in network topologies can be overcome by using novel approaches such as dynamic reconfiguration of GAP roles between Central and Peripheral. Cypress’ PSoC 4 BLE provides a solution that integrates all requirements for IoT applications while also making it very easy-to-implement by providing free software tools, low-cost development kits and hundreds of design examples to get you started with.
