ST STDES-BLUEPLUG2 User manual

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.

1Safety information
FCC notices
Note: ST reference designs and evaluation boards are intended to help and facilitate development of products. Using
a direct copy of any of them does not waive the requirement for testing and certification of products mandated by
governing agencies and authorities.
This device compiles with part 15 of the FCC Rules. Operation is subject to the following two conditions:
1. This device may not cause harmful interference
2. This device must accept any interference received, including interference that may cause undesired
operation.
Electrical safety
Danger:
Due to the high voltage present on the non-isolated components, special care must be taken to
avoid the risk of electric shocks and burns.
There are no protections against accidental human contact with high voltage components.
Never touch live board components when the board is connected or immediately after the board is
disconnected, as the capacitors may still be charged.
Do not connect probes to any high voltage components if the board is not isolated from the mains
supply, as this may cause damage to equipment.
1. The board must be used only by qualified persons.
2. De-energize the board and all its interface outputs and electrical loads before performing any electrical or
diagnostic operations.
3. Only program and debug the board with the isolated JTAG in-circuit debugger/programmer to avoid
damaging the tools.
4. Use a mains insulation transformer when you perform any tests with spectrum analyzers or oscilloscopes.
Note: STMicroelectronics assumes no responsibility for accidents or injury caused by improper use of this
development tool.
Personal safety
1. Wear personal protective equipment such as latex gloves or safety glasses with side shields, or protect the
EVM in an adequate lucent plastic box with interlocks from accidental touch.

Figure 3. STDES-BLUEPLUG2 block diagram
The mains supply and loads are monitored by the STPM32TR standard metering IC, while the BLUENRG-M2SP
Bluetooth Low Energy module handles data and command interfacing for the ST BLE PLUG Android app
developed for the board, and can store data via the EEPROM connector.
The 12 A TRIAC acts as a switch for the load and phase controller for dimming.
The supplies for the ICs are regulated from the VIPER06XS buck converter output.
The board includes a manual switch to turn the load on and off, and LEDs to signal connectivity status.
2.4 Zero crossing detector circuit
A zero crossing circuit is an electrical circuit that begins operation with the AC load voltage at close to 0 V in the
AC cycle. Zero crossing detection is used for the dimming reference point to fire the TRIAC accordingly.
The circuit has three resistors connected to phase of the AC line to lower the resultant voltage and a resistor on
the base of a PNP transistor which acts as a pull up resistor: when the voltage at the base drops below the base
operating voltage, the transistor switches to output LOW.

Zero crossing detector circuit
UM2862 - Rev 2 page 5/25

The purpose of the circuit in our design is to start the TRIAC conducting very near the moment when the load
voltage crosses zero volts (at the beginning or the middle of each AC cycle represented by a sine wave), so that
the output voltage can be modified by changing the firing angle of TRIAC, which in turn will change the required
output waveform.

2.5 Power supply
For power supply, a non-isolated Buck converter using the VIPER06XS offline converter is used, with PWM
operation at 30 kHz and frequency jittering for lower EMI. Standby power is very low, at < 30 mW.
UM2862
Power supply
UM2862 - Rev 2 page 6/25

This type of supply is ideal for the ST BLE PLUG application, where large currents are not required, but a small
form factor is necessary.

The following events occur in the state machine figured above:
1. The peripherals are initialized, including:
– USART for STPM
– the timer for firing the TRIAC
– I2C for the NFC/RFID EEPROM
– GPIOs and System Clock.
2. In the RUN state, the API constantly checks for data packets from the BLE device.
3. Metering interrupts are performed at 1 Hz, and the data is sent to the BLE device, according to the user
settings.
4. An interrupt updates the data packet.
5. The TRIAC is fired according to the data packet.
