Note : This bluetooth module had tested for the connection between Arduino board and Android phone only. For using this module with iPhone or other smart phone/device. Please make sure you understand the connection method and coding.
Product Features :
1. The core module from the module using the HC-06 , leads interface includes VCC, GND, TXD, RXD, aside LED status output pin , the microcontroller can be connected via Bluetooth to determine whether the pin state , KEY pin on the slave is invalid.
2. Led indicate Bluetooth connection status , flashes to indicate there is no Bluetooth connection , Steady Bluetooth port is connected and turned on.
3. The board is 3.3V LDO, the input voltage is 3.6 ~ 6V, when unpaired current is about 30mA, the pairing is about 10mA, the input voltage must not exceed 7V!
4. The interface level is 3.3V, you can directly connect a variety of SCM (51, AVR, PIC, ARM, MSP430 , etc. ), 5V microcontroller can also be connected directly , but, without using MAX232 and can not go through MAX232!
5. 10 meters effective distance, over 10 meters are possible, but do not garranty the connection quality for over effective distance.
6. Using full-duplex serial port after successfully paired; without having to know any Bluetooth protocol, but only supports 8 data bits, 1 stop bit , no parity communication format , which is the most common communication format , not support other formats .
7. When not establish a Bluetooth connection, it support setting the baud rate , the name , the pairing password via AT commands , parameter set -down to save. After Bluetooth connected, it is automatically switched to transparent mode.
8. Small size (3.57cm * 1.52cm), chip production plant to ensure the quality of the patch . Using the transparent shrink tube to protect from dust, and there is some
anti-static capabilities.
9. Able to build the link from the machine, computer , Bluetooth with Bluetooth from a host with a variety of functions , most Bluetooth phones , PDA, PSP and other intelligent terminal pairing, but slave devices can not be paired .
=====================================
Linvor 1.5 also known as HC-06
This firmware offers a very limited set of AT
command.
By default the baud rate is 9600 8N1.
For this firmware you have to not send LF or CR
character at the end of your AT command.AT programming mode is up when your
board is not paired by bluetooth devices. For this firmware, you have to
copy/paste AT command since timings is important. You can send about one
command per second.

And that's it
!!! No other AT command.
TIPS : Because of the input timing, please use copy and paste to input
AT command.
=====================================
Tips:
TXD: the sending end, generally expressed as their transmitter, normal communication must be connected to RXD another device.
RXD: the receiving end, generally expressed as their receiving end, the normal communication TXD must be connected to another device.
Itself when normal communication TXD RXD devices connected forever!
