1, Tips ( very important ):
TXD: the sending end , generally played as their transmitter, normal communication must be connected to the RXD Pin of the other device .
RXD: the receiving end, generally played as their receiving end, the normal communication must be connected to the TXD Pin of the other device.
Loop Test (TXD Connect to RXD) :
In order to test whether the Bluetooth module has the normal data sending & receiving ability, can use the Bluetooth device(Smartphone) to connect to the Bluetooth module, and the Bluetooth module’s TXD Pin connect to the RXD Pin, send the data via Smartphone Bluetooth assistance app, if the received data is same as the data sent via Bluetooth assistance app, that means the Bluetooth module working in good condition.
2, Level Logic:
TTL level: typically binary data representation , +5 V equivalent to the predetermined logical 1, 0V is equivalent to logic 0, the system is called a TTL signal is positive logic.
RS232 level: -12V used to -3V, equivalent to a logic 0, +3 V to +12 V logic level is equivalent to logic 1 , negative logic
3, Main Features :
1)The using method for KEY Pin:
Assume that the present status is transparent transmission mode, set this pin as high level, will enter to AT Command Mode, can set the parameter and inquiry parameter information; Set this pin as low level, will back to transparent transmission mode.
Remarks: Status and Key Pin can be work as the flow control pin. Before using this specified functions, please confirm with our technical staff.
2)LED Bluetooth Connection Indicator: Pairing Mode—Slow Shinning, Searching Mode--Quick Shinning, Connected—Stable Lighting.
3).With Power Anti-Reverse Diode,3.3V LDO, Input Voltage 3.6~6V(mustn’t be more than 7V!!),under not paired mode, consumption current ~30mA,Paired mode ,consumption current ~20mA.
4).Interface Level is 3.3V,can directly connect to different kinds of SCM(Such as 51,AVR,PIC,ARM,MSP430, etc),also can directly connect to the 5V Interface Level SCM (Such as our FSC-BT826N)
5).Around 30M coverage in open area (Power Level Class 1.5),more than 30M distance, we are not guarantee for the connection stability.
6).After Pairing successfully, work as Full Duplex Serial port, support the baud rate from 4800bps~921600bps,no need any Bluetooth protocol knowledge, support multiple communication format, such as the 8 bit data bits ,1 bit stop bit, No Parity Checking, etc
7).Support to set the high level for KEY Pin ,can enter to AT Command Mode ,set parameter and inquiry data information anytime.
8).Mini Size(3.57*1.52cm),strict SMT Process, with transparent heat-shrinkable tube, anti-dust & anti-static.
9).Default Mode: Pairing Mode, can search and connect to designated device, please check our manual for more details.
10) The default mode for FSC-DB004 is without button, adding button option is available.
Here’s the brief introduction for the button using method:
1> If the present status is connected, short press this button, will disconnect the present status.
2> If the present status is disconnected, short press this button, will connect to the latest paired device at the fastest way.
3> Under any work status, long press this button 3 seconds, auto enter to the searching and connection mode, default mode is choose the strongest signal Bluetooth device(if already connected to other device, will disconnect it.)
Reminder : Do not connect the power to the signal pin, will burn the module.
After paired, can be used as the normal fixed baud rate serial port. Any devices with Fixed baud rate,8 bit data bits, no parity checking communication format, can replace the old serial port which with cable connection ,no need to modify the software. Mainly applied to data collection, smart car, serial port printer, outdoor dot matrix screen control, etc.
1> Pairing using with computer: Computer and Bluetooth devices start the communication via Bluetooth serial port, using method same as serial port communication.
2> Pairing using with Smartphone: Smartphone and Bluetooth devices start the communication via Bluetooth serial port, using method same as serial port communication.
3> Pairing using with Bluetooth host device: two devices start the communication via Bluetooth serial port, such as SCM to SCM, Serial port with cable to SCM, etc, using method same as serial port communication.
5, Flexible use:
1).Baud rate conversion: because the receiver and the sender module can choose their own baud rate, during small data transmission period, these modules can be work as baud rate conversion device.
2).Status and Key Pin can be work as the flow control pin. Before using this specified functions, please confirm with our technical staff.

Things You Need To Know For Bluetooth Modules:
1 What is Bluetooth 4.0:
Bluetooth 4.0 is consists of Bluetooth Basic Rate (BR)/Enhanced Data Rate (EDR), High Speed (HS) and Low Energy (LE), Bluetooth 4.0 covers the Bluetooth 2.0,2.1,3.0 Versions. Nowadays, there are a lot of devices powered by Bluetooth 4.0, such as Bluetooth Earphone, Speakers, Vehicle Electronic Equipment, OBD, Printer, Barcode Scanner, Mobile Medical Device, Bracelet, Pedometer, etc.
2 What is Bluetooth Dual Mode Module:
Bluetooth Dual Mode Module is a Single-Module Bluetooth Solution with Built-in Bluetooth Basic Rate (BR)/Enhanced Data Rate (EDR)/Low Energy (LE) Functions.
3 What is BLE Module:
BLE Module is a Single-Module Bluetooth Solution with Built-in Bluetooth Low Energy (LE) Function.
4 What are the Bluetooth Dual Mode Advantages:
There are two most frequently applied Bluetooth Profiles for the general data communication between Smart Device and Bluetooth Peripheral: BLE and SPP.
In iOS, SPP is Only Available after the Bluetooth Peripheral passed the MFi Certification, in view of the high cost and complex process of the MFi Certification, BLE is much good to use. In Android Camp, BLE is Only supported by Android 4.3 and later versions of the Android OS, this lead to the serious system fragmentation issues and make a lot of Android devices has the bad compatibility for the BLE, so SPP has a huge advantage for data communication in android.
In Summary, If one product need to support iOS and Android devices simultaneously, our Bluetooth dual mode modules are the best choice.
5 What is the transmission distance for Bluetooth Modules:
Class 2 : 10M Class 1: 100M
6 What is the transmission speed For Classic Bluetooth Module SPP & BLE 4.0
Under Ideal Condition:
SPP: About 80KBytes/s
BLE: About 8KBytes/s
(Remarks: When starts the audio transmission ,the transmission speed for both types will be decreased. When music on, BLE transmission speed is about 1~2KBytes/s )
