ST STDES-BLUEPLUG2, User Manual

Page: 1 / 25

Introduction
The STDES-BLUEPLUG2 is a reference design for home-automation and Internet of Things (IoT) applications.
The on-board BLUENRG-M2SP is compliant with Bluetooth Low Energy (BLE) specification 5.2 to allow secure communication
of metering data from specific electrical loads to a smart phone with BLE support.
It supports multiple roles simultaneously and can act at the same time as Bluetooth smart master and slave device.
The device current consumption on AC mains is 3 to 7 mA.
The device acts as BLE peripheral device which can be connected to any smart device using the Android ST BLE PLUG app
(available for free download on Google Play) to control and monitor the load and its energy parameters.
The app features load ON/OFF turning, scheduling, dimming and metering parameters.
The STDES-BLUEPLUG2 embeds an STPM32 metering chip for high accuracy measurement of power and energy in power
line systems using shunt current sensors, a three-terminal TRIAC which controls the current through AC switching for various
electrical system applications, and a non-isolated buck converter supply based on the
VIPER06XS . This type of supply is ideal
for the applications (like ST BLE PLUG ) where a large amount of current is not needed and a small form factor is required.
The STDES-BLUEPLUG2 is a fully assembled board developed for performance evaluation only, not available for sale.
