1 What is Bluetooth?
Page 5 / 23
1 What is Bluetooth?
1.1 Features of Bluetooth
Objectives of Bluetooth : To Realize Wireless Communication for Short Distance with Low Power
Consumption, High Reliability, and Low Cost.
Frequency in Use: To Use ISM(Industrial, Scientific, Medical) Band which does not require any
permission to use.
-2.400 –2.4835 GHz, 79 channels
-2.465 –2.4835 GHz, 23 channels (in France)
Transmission Rate : 1Mbps ~ 3Mbps
Transmission Output : 1mW (10m, Class2), 100mW (100m Class1)
Network Configuration : Configured with Master and Slave relation. A Bluetooth unit shall allow
simultaneous connections up to 7 devices (in case of ACL).
Reliability : To Guarantee stable wireless communication even under severe noisy environment
through adopting the technique of FHSS (Frequency Hopping Spread Spectrum).
1.2 Operation of Bluetooth
<Feature 1-1 Bluetooth Operation>
Bluetooth operates based on the connection between “Master”and “Slave”.
Masters are simply supposed to do “Inquiry”and “Page”. Slaves are supposed to do “Inquiry Scan”
and “Page Scan”.
If a Master finds a Slave and so “inquiry”is successful, a Slave responds to the Master with its
information.
Interconnection between the Master and the Slave is achieved only if the information from the Slave is
corresponded with the Master, and the Slave sends data to the Master.

Connection Status
Signal Status
Description
When not Connected
HIGH (3V)
Shows the unconnected status in the standby mode
for AT Command
When Connected
LOW (0V)
Shows the connected status with the other
Bluetooth device. This status allows the HID Report
to be sent to the other device.
When Connecting
LOW –HIGH Repeat
Repeats LOW and HIGH at regular intervals and
shows the connecting status to the other Bluetooth
device.
<Table 5-1 status of the STATUS>
- HID STATUS (No. 6)
Show the status of the HID.
When the HID profile is connected, it repeats LOW - HIGH at regular intervals. If data is not input into the
UART, the HID enters the Sniff mode (low power), and the repetition of LOW - HIGH becomes slower.
When data is input into the UART, the repetition of LOW - HIGH becomes faster.
- MULTI FUNCTION (No. 4)
In MULTI FUNCTION, several functions are defined. Each operation is as shown in the following table.
No

10 How to Use - FB155BC(HID)
It is a device that operates as a keyboard or mouse by transmitting an HID Keyboard Report or HID Mouse
Report via UART when FB155BC(HID) is connected with the other Bluetooth device. To generate an HID
Report, external MCU or HID Report to UART program is required. Firmtech offers a test board and Smart
HID Interface Kit providing sample source as options.
The connection control method is the same as other devices of Firmtech. When connection is made with
other Bluetooth device, it can transmit keyboard and mouse status by transmitting the below HID Report
value.
