The new wireless protocol Bluetooth Smart / Bluetooth Smart Ready is being implemented in an increasing number of devices, especially smart phones. This popularity is expected to lead to many embedded systems applications that draw on this wireless communication infrastructure. In most cases, batteries are foreseen as energy source. However, the low power nature of Ble makes it an attractive communication channel for applications powered by Energy Harvesting. After a review of the needed specification information, we will discuss issues that are relevant to the use of Bluetooth Smart with energy harvesting. Drawing on examples of practical systems that we have designed, built and tested, we will highlight the relevant weak points and show how the associated problems can be solved.
