Linksprite-Yuki Posted September 4, 2016 Report Share Posted September 4, 2016 BLE4.0 Shield is an arduino shield which based on TICC2541. The AT instruction set integrated by BLE4.0 module is simple and effective to use, and greatly shorten your developing period. Based on the bluetooth standard specification, Bluetooth Low Energy (BLE) technology allows BLE4.0 to further reduce peak power to half, comparing with traditional Bluetooth devices. The single-mode chip of Blue tooth4.0 (BLE) enables to work for a long time (up to several months even years), powered by single button battery. Instead, traditional Bluetooth technology generally asks for at least two AA batteries, meanwhile at most works for several days or weeks. The main disadvantage of previous blue tooth version is extremely low startup speed. For example, Blue tooth 2.1 spends 4s to startup, but it’s only takes 3 ms for Blue tooth 4.0 to startup. If comparing Blue tooth 2.1 to a basic “feature phone”, then, Blue tooth 4.0 would be a “smart phone”.
