Configuring Lansitec BLE Beacon with an iPhone #

Notice: all parameters are in hexadecimal coding.

Sてp 1: Search and download ‘LightBlue’ in App Store.

ステップ2: Power up. Open the beacon and turn it on. A red light will blink once it is on.

ステップ3: Open LightBlue, a beacon with “LS_Beacon” will show in the app, click the corresponding one to enter the configuration page. Please click the iBeacon within 1 minute after power on or it must be restarted to enter the configuration mode again.

Major Configuration:

1. Click “Major”;
2. Click “Write new value”;
3. Enter new Major value;
4. Click “Done” to save;
5. Click the Back sign (step 7) to return to the Peripheral page;
6. Click “Back” (step 8) to exit the configuration. The change will not be saved if no existing the configuration.

Use the same way to configure minor, UUID, TX power, or other parameters. Please exit LightBlue after configuration. The light stops blinking after configuration.

Advertising Feature #

The beacon broadcasts the entire 30-byte advertising packet in all advertising frequencies using a fixed 100 ms advertising interval.

About accuracy, several factors influence the accuracy distance measuring with BLE RSSI.

1. Shadow effect: signals can be reflected by walls and glasses around many times during the transmission. If there is an object moving due to diffraction, the signal path will be changed. This results in receiving unstable signal strength.
2. There are many devices on 2.4G, Wi-Fi, Bluetooth, Zigbee. The signal may overlap with each other which makes the received signal strength unstable.

When using a beacon for positioning, please consider the follow 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. 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, refer to document number 930-00171.
2. Position Calibration, refer to document number 930-00172.
