No battery or wires, BLE reference design
A reference design has been introduced by ZF for an Energy Harvesting Bluetooth Low Energy Switch in a partnership with ON Semiconductor. The design combines ZF’s energy harvesting generator with the industry’s lowest power Bluetooth 5 radio RSL10 SIP from ON Semiconductor and is a well suited solution for the rapidly growing number of applications for BLE communication.
The generator, incorporated with the RSL10 SIP, enables designers to develop bespoke battery-free and wireless control solutions for a wide range of low cost, low-energy applications. The transmitter is designed for evaluation. For integration into an application the PCB wings can be cut to size.
The reference design works in Advertising Mode with uni-directional uplink communication and offers various pairing options. The operation can be shown via a smartphone app (IOS: Bluetooth Smart Scanner and Android: Bluetooth Low Energy Analyser) which displays all received telegrams.
A supporting demo kit based on the reference design for the Energy Harvesting Bluetooth Low Energy Switch, and ON Semiconductor’s Bluetooth IoT Development Kit (B-IDK) is also available from ON Semiconductor. The kit shows the capabilities of the battery-free and wireless switch in combination with an LED lighting application.
