What is a BLE low-power module?
The Bluetooth Low Energy Module (BLE) is a hardware module that integrates the BLE radio frequency chip, antenna, protocol stack and necessary peripheral circuits. Its core design objective is to conduct intermittent and small-data-volume wireless communication with extremely low power consumption.
In simple terms, it is like an "energy-saving messenger" designed for Internet of Things devices. It spends most of its time "sleeping" and is only "awakened" when it needs to send or receive data. Therefore, its energy consumption is extremely low, and a single button battery can sustain its operation for months or even years.
