Manual do usuário da etiqueta do sinalizador Bluetooth B002

General Introduction #

The B002 beacon is equipped with a three-axis acceleration sensor that can detect whether it is in motion. It can switch between two different advertising modes ( Periodic Mode e Autonomous Mode) by changing the Accelerometer Threshold value. It also supports detecting and advertising the battery level. In autonomous mode, it can advertise every 24 hours if it is not moved.

Intervalo de anúncio #

The interval of beacon advertisement is 5s in default, this means that the beacon advertises the advertising packet once every 5s. The maximum Advertisement interval is 10s.

	05000000	500
	…	…
	64000000	10,000

Accelerometer Threshold #

The Accelerometer threshold value is 0x00 by default which means that autonomous mode is disabled and the beacon advertises in the Periodic Mode. When the Accelerometer threshold value is greater than or equal to 0x10, the beacon advertises in the Autonomous Mode. The beacon is considered in motion when the accelerated speed is larger than the threshold. The default unit is 16mg, Accelerometer threshold = value * 16mg.

Advertise Mode #

Periodic Mode #

In the periodic mode, the beacon advertises the advertising packet at fixed intervals as configured until the battery power runs out.

Autonomous Mode #

In the autonomous mode, the beacon only advertises when it is in motion. When the acceleration is larger than the Accelerometer threshold, the beacon advertises with the Anunciar Interval value for the duration of the Advert Time.

For example, if the interval value is 5s and the advert time is 1min, the beacon will not advertise if it is stationary. When the acceleration is larger than the Accelerometer threshold, the beacon will advertise once every 5s and keep advertising for 1min.

Advert Time #

The duration of the beacon advertisement is 0000 by default, and the maximum advertise time is 65535s. This configuration only works in autonomous mode. If the beacon works in periodic mode, this configuration has no effect.

Table 5: Advert Time

Tipo de valor	Valor	Time (s)

Switch Configuration #

The B002 beacon has two switch functions: “Battery Level Advert” and “No Movement 24h Advert”. The “Battery Level Advert” function determines whether the beacon advertises with the battery level. The “No Movement 24h Advert” function determines whether the beacon advertises every 24 hours if it is not moved.

Table 6: Switch Configuration

Name	Valor	Description
Battery Level Advert	00:disabled, 01:enabled,the default value is 0.	This configuration determines whether the beacon advertises the battery level.
No Movement 24h Advert	00:disabled, 01:enabled,the default value is 0.	This configuration only works in autonomous mode, where the beacon advertises every 24 hours if it is not moved.In periodic mode, this configuration has no effect.

Recurso de publicidade #

Em Periodic Mode, the beacon advertises a 30-byte packet with a fixed 5s Intervalo de anúncio. In Autonomous Mode, the beacon only advertises with the advertise interval value for the duration of the Advert Time when it is in motion and will not advertise when it is stationary.

The beacon advertising packet is as follows.

Standard Advertising Packet #

The beacon advertises a standard advertising packet when the battery level feature is not enabled.

Note：

Regarding accuracy, several factors influence the accuracy of distance measurements with BLE RSSI.

1. Shadow effect: signals can be reflected by walls and glasses around many times during the transmission. Diffraction changes the signal path This results in receiving unstable signal strength.
2. There are many devices on 2.4G, Wi-Fi, Bluetooth, and Zigbee. The signal may overlap, making the received signal strength unstable.
3. Due to the semiconductor manufacturing limitation, TX power is not stable.

When using a beacon for positioning, please consider the following method for measuring the distance.

1. While the beacon is advertising, repeatedly sample the RSSI at a 1-meter distance for a minimum of 10 seconds.
2. Discard the highest 10% of the RSSI samples.
3. Discard the lowest 20% of the RSSI samples.
4. Calcule a média das amostras restantes para obter o valor da Potência Medida.

Recomendamos outros dois algoritmos para calcular a distância e a posição:

1. Moving average algorithm, Lansitec document number 930-00171.
2. Position Calibration, Lansitec document number 930-00172.
