About BLE Bluetooth Remote Control
BLE (Bluetooth Low Energy) remote control is a low-cost, short-range, interoperable, robust wireless technology that operates in the unlicensed 2.4GHz ISM radio frequency band. It was designed from the outset as an ultra-low-power (ULP) wireless technology. It employs various smart techniques to minimize power consumption.
Bluetooth Low Energy technology uses variable connection intervals, which can be set from a few milliseconds to several seconds depending on the specific application. Additionally, because BLE technology employs a very fast connection method, it can remain in a “disconnected” state most of the time (saving energy), where both ends of the link are aware of each other, only establishing the link when necessary and closing it as quickly as possible.
