# B003 & B004 Bluetooth Beacon User Manual

## General Introduction

The [B003](https://www.lansitec.com/products/mini-smart-bluetooth-tracker-beacon-tag/) and [B004](https://www.lansitec.com/products/smart-bluetooth-tracker-beacon-tag) beacon support detecting and advertising the battery level and advertises BLE packages according to a fixed interval. It supports a low battery alert and a panic button.

![Mini Smart Bluetooth Tracker Beacon Tag](https://www.lansitec.com/wp-content/uploads/2024/03/B003-Bluetooth-Beacon.png)
The mini smart bluetooth tracker beacon tag is a device that helps you find your personal belongings quickly and easily. You can attach the beacon to anything you want to keep track of, and it will buzz when it communicates with the gateway.

## Function Description

### On/Off Status

1. Turn on: Press the button for 3s and the LED flashes 10 times.
2. Turn off: Press the button for 3s, and the LED flashes 3 times quickly.

### Low Battery Alert

The beacon checks the voltage every hour. If the battery power is below 20%, the beacon will beep every minute as a warning. To stop the alarm, press the button three times. The alarm will resume after the next voltage check if the battery power is still low.

### Panic Button

When the panic button is enabled, the Major field's high bit (binary 1) signifies the panic state. The beacon advertises the status 10 times with the set interval. For example, if the Major is 0x0010 and the Minor is F1BC. Major becomes 0x8010.

0x02 01 06 1A FF 4C 00 02 15 F2 A5 2D 43 E0 AB 48 9C B6 4C 4A 83 00 14 67 20 00 10 F1 BC B3 (panic button not pressed)

The panic button is enabled by default. Please get in touch with Lansitec if you do not need it.

### TX Power

The signal strength sent by the beacon. The default value 06 (0dBm)

******Note******:

*Regarding accuracy, several factors influence the accuracy of distance measurements with BLE [RSSI](https://www.lansitec.com/ko/blogs/rssi-실내-위치-측정/).*

1. *Shadow effect: Signals can be reflected by walls and glasses many times during transmission.**D**iffraction changes the signal path, Which 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](https://www.lansitec.com/ko/blogs/iot-추적을-위한-tx-전력-최적화-범위-개선-배터리-수명-규/) 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](https://www.lansitec.com/ko/blogs/rssi-실내-위치-측정/) at a 1-meter distance for a minimum of 10 seconds.*
2. *Discard the highest 10% of the [RSSI](https://www.lansitec.com/ko/blogs/rssi-실내-위치-측정/) samples.*
3. *Discard the lowest 20% of the [RSSI](https://www.lansitec.com/ko/blogs/rssi-실내-위치-측정/) samples.*
4. *Average the remaining samples to obtain the Measured Power value.*

*We recommend another two algorithms for calculating the distance and position:*

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