1 What is Bluetooth?
페이지 5 / 12
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.

- STATUS port
To be used to monitor the status of FBL601BC_serial
It keeps LOW (0V) when the Bluetooth wireless section is connected smoothly and both devices can
communicate
In standby mode for connection with Bluetooth, or connection trial, or searching for around Bluetooth
device will repeat LOW and HIGH.

-FA_SET / CONFIG_SELECT
If you want to enter the configuration mode, turn on the power to the module while inputting LOW Signal
(0V) to Configuration Select (No. 4 pin).
If you want to change to the factory default value, enter the LOW Signal (0V) for more than 5 seconds into
the Factory Reset (Pin No. 4) after entering the configuration mode and all setting values will be changed to
the original purchase status.
- Power Save Control Port
Select FBL601BC_serial's Power Save ON/OFF Control When high is applied it operates as Power Save On
