How to program the XS3868 bluetooth audio module through arduino? Answered

I just want to know if I can connect a mic to it and have a two way bluetooth radio. Actually I have a HAM gear and I want to connect it to Spk/Mic and be able to Rx and Tx audio from it

Hi buddy ... ;)

do you know how to send a character by xs3868 ?
I have found a command (AT#ST) that can send char...

I have installed an bluetooth terminal in my phone and wrote this code :
AT#STdata ( "data" is the string that I wanna send )
but there was nothing in my phone ...
what is wrong with it ???????????
:(

I have written an instructable for the entire process:

Hi I want pairing tow xs3686 module together?Please help me

you would probably have to have an arduino library installed

and it would probably have to have an arduino controller to store the code

and other stuff like that

i have a problem! my phone connects to the BT but disconnects after 4-5 seconds. any idea?

Dear LazyH,

I am sure you have already solved this problem. However, I will publish my modest results here, because I myself spent quite a lot of time trying to work this small piece of hardware, I mean, xs3868 module based on the OVC3860 chip, and I could never find any sensible description.

I sent the AT commands from my Win 7 PC through the serial port using the USB-UART bridge based on the CP2102 chip. It is now really cheap. See, for example, "NEW CP2102 USB 2.0 to UART TTL 5PIN Module Serial Converter for Arduino YP",

http://www.ebay.com/itm/NEW-CP2102-USB-2-0-to-UART-TTL-5PIN-Module-Serial-Converter-for-Arduino-YP-/151761367424?hash=item2355aeb180:g:XBMAAOSw9N1VuJNd

I used Python, specifically IPython environment which is as convenient as Matlab, if you know it. Just key in a command and instantly get the response from the device. I used the PySerial Python module.

Here is a Python script where I gathered the AT commands I sent to xs3868 today.

#

# Sending AT commands via the serial port to the Blurtooth transceiver

import serial

ser = serial.Serial(port='COM5', baudrate=115200, timeout=.01)

print 'ser.isOpen() = ', ser.isOpen()

# Enter pairing

ser.write("AT#CA\r\n"); print '"AT#CA" -> ', ser.read(128)

# Cancel pairing

ser.write("AT#CB\r\n"); print '"AT#CB" -> ', ser.read(128)

# Query status

ser.write("AT#CY\r\n"); print '"AT#CY" -> ', ser.read(128)

# Reset

ser.write("AT#CZ\r\n"); print '"AT#CZ" -> ', ser.read(128)

# Query status

ser.write("AT#CY\r\n"); print '"AT#CY" -> ', ser.read(128)

# Play/Pause

ser.write("AT#MA\r\n"); print '"AT#MA" -> ', ser.read(128)

# Stop

ser.write("AT#MC\r\n"); print '"AT#MC" -> ', ser.read(128)

# Connect to av source

ser.write("AT#MI\r\n"); print '"AT#MI" -> ', ser.read(128)

# Disconnect from av source

ser.write("AT#MJ\r\n"); print '"AT#MJ" -> ', ser.read(128)

# Query avrcp status

ser.write("AT#MO\r\n"); print '"AT#MO" -> ', ser.read(128)

# Start FF

ser.write("AT#MR\r\n"); print '"AT#MR" -> ', ser.read(128)

# Start Rewind

ser.write("AT#MS\r\n"); print '"AT#MS" -> ', ser.read(128)

# Stop FF/Rewind

ser.write("AT#MT\r\n"); print '"AT#MT" -> ', ser.read(128)

# Query A2DP Status

ser.write("AT#MV\r\n"); print '"AT#MV" -> ', ser.read(128)

# Decrease Volume

ser.write("AT#VD\r\n"); print '"AT#VD" -> ', ser.read(128)

# Increase Volume

ser.write("AT#VU\r\n"); print '"AT#VU" -> ', ser.read(128)

# Read a byte from memory

ser.write("AT#MX08001AC4\r\n"); print '"AT#MX08001AC4" -> ', ser.read(128)

# Print 64 bytes of memory starting from 0x08000000

for a in xrange(64):

addr = 0x08000000 + a

ser.write("AT#MX"+hex(addr)+"\r\n")

r = ser.read(128)

i = r.find('MEM:') # Index of first letter of "MEM:" in r

r = r[i+4:] # Cut away up to end of 'MEM:'

i = r.find('\r') # Index of first letter "\r" in r

# In hexadecimal, 2 digits with leading zero:

print '%08x: %02x ' % (addr, int(r[:i], base=16))

ser.close()

If you have any questions, please do not hesitate to ask me.

Hey I am also a little curious whether you where able to change the password as well as the name?

Try connecting Tx-Tx and Rx-Rx. BTW use a level shifter. There is some problem with Tx Rx pins on Arduino Uno. I did the same on my ESP8266 and Tx-Tx connection works. But when I was using hardware serial with atmega328 plugged in with HC05 module, Tx-Rx connection worked. Just put a voltage divider on Rx pin of arduino Uno connect Tx-Tx Rx-Rx and see if it works

this video has the correct connections, in time 1:47

using the serial in different pins TX / RX Arduino (10 and 11 example)

commands at: http://labdegaragem.com/forum/topics/hc-06-comando...

I connected to the same video, loaded the software and sent commands smoothly. I could not receive data. Probably do voltage divider as similar HC05

boards are different (v1.2 X v2.0)

Hi,

Nice post. Do you have some news or updates ?

I 'm trying to do exactly the same.

It was for a friend birthday and i started to build diffrents king of speaker's.

The bithday was in November and he is still waiting for it ;-)

I couldn't change the name on the BT controleur.

I tried with an HC-05 & 06 i could change the name but couldn't use it as a Bluetooth audio receiver.

I also bought a BT usb audio receiver stick with rt/tx but couldn't talk to it.

I don't have a lot of knowledge and experience at this anyway and got an Arduino Uno fiew month ago.

Did you find any solutions or alternatives ?

Did you aske the resseller if they know how to do that ?

Than

Hard to say. The datasheet is in Mandarin. Its HIGHLY unlikely to be anything but 3v3 logic - NOT TTL, which is 5V. You'll need to create RS232 for your USB interface, unless you are using one of FTDI's interface cables, with 3v3 logic out.
