Bluetooth Services

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

RedBear Beacon Service  UUID: B0702980-A295-A8AB-F734-031A98A512DE

- for Beacon settings, more details in next section

Device Information Service  UUID: 180A

There are two characteristics you should pay attention to.
1. UUID: 2A28, Software Revision String
- this represents the software revision for the Beacon software within B1, the latest version is "20131128"
2. UUID: 38837046-FE96-4335-B751-D4826198F337, Device Name String
- you can rename the broadcasting device name of your B1

Battery Service  UUID: 180F
- 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: E6775403-F0DD-40C4-87DB-95E755738AD1
- for Over-The-Air firmware upgrade

RedBear Beacon Service

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

1. Beacon UUID  UUID: 0xB0702881-A295-A8AB-F734-031A98A512DE
- a unique 16-bytes value in HEX for advertising

2. Major identity ID  UUID: 0xB0702882-A295-A8AB-F734-031A98A512DE
- a 2-bytes value, ranging from 0 to 65535 (0xFFFF)

3. Minor identity ID  UUID: 0xB0702883-A295-A8AB-F734-031A98A512DE
- a 2-bytes value, ranging from 0 to 65535 (0xFFFF)

4. Measured Power  UUID: 0xB0702884-A295-A8AB-F734-031A98A512DE
- 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 Beacon

5. LED Switch  UUID: 0xB0702885-A295-A8AB-F734-031A98A512DE
- a 1-byte value used to control the on-board green LED, either OFF (0x00) or ON (0x01)
- default is ON

6. Advertising Interval  UUID: 0xB0702886-A295-A8AB-F734-031A98A512DE
- a 2-bytes value, ranging from 100ms (0x0064) to 10000ms (0x2710) on a incremental of 5ms unit
- default is 250ms

- the time between each Beacon 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. Output Power  UUID: 0xB0702887-A295-A8AB-F734-031A98A512DE
- 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.
