Beacon B1 Instruction

Under maintenance mode, there are four Bluetooth Low Energy services available.

RedBear Beacon Service  UUID: 

Device Information Service  UUID: 

There are two characteristics you should pay attention to.
1. UUID:

, Software Revision String

- this represents the software revision for the Beacon software within B1, the latest version is “20131128”
2. UUID: 

, Device Name String

- you can rename the broadcasting device name of your B1

Battery Service  UUID: 

- showing the remain battery life as a percentage

- please noted that the Red LED light on B1 will keep flashing when battery level fall to 30% or below

Firmware Upgrade Service  UUID: 

- reserved for Over-The-Air firmware upgrade

Under RedBear Beacon Service, there are seven Bluetooth Low Energy characteristics.

1. iBeacon UUID  UUID: 

- a unique 16-bytes value in HEX for advertising

2. iBeacon Major identity ID  UUID: 

- a 2-bytes value, ranging from 0 to 65535 (0xFFFF)

3. iBeacon Minor identity ID  UUID: 

- a 2-bytes value, ranging from 0 to 65535 (0xFFFF)

4. iBeacon Measured Power  UUID: 

- a 1-byte signed value, ranging from -100 to 0

- This is an average RSSI (Received Signal Strength Indication) of the beacon measured at approximately one meter 

from an iOS device. This is a reference value in order for iOS to determine the distance between an iOS device and 

a beacon.

- Please refer to Apple’s AirLocate sample about how to obtain Measured Power for your iBeacon

5. LED Switch  UUID: 

- a 1-byte value used to control the on-board green LED, either OFF (0x00) or ON (0x01)

- default is ON

6. iBeacon Advertising Interval  UUID: 

- a 2-bytes value, ranging from 100ms (0x0064) to 10000ms (0x2710) on a incremental of 5ms unit

- default is 250ms

- the time between each iBeacon signal broadcasted; shorter time will have better response time and accuracy, however 

this will increase the power consumption due to more broadcasting in the same period of time.

7. iBeacon Output Power  UUID: 

- a 1-byte value, four available settings: -23dBm (0x00), -6dBm (0x01), 0dBm (0x02) or 4dBm (0x03)

- default is 0dBm (*our beacon is optimized to run at 0dBm.)

- the output power setting of the Texas Instruments CC254x IC; higher power should mean longer range and higher 

power consumption.
