Arduino UNO and HC-05

Hi friends wich is the correct diagram for configure the Arduino and HC-05 device?

i have a diagram similar to http://postimg.org/image/j82llapgj/

my cell phone detect the bluetooth, but cant type AT commands

i think my configuration is BAD.

wich programs in the cell phone do you recommend me?

and for send AT commands ?

Thanks for your help

i follow this steps:

http://www.instructables.com/id/Modify-The-HC-05-Bluetooth-Module-Defaults-Using-A/step1/Components-Wiring/

i am stopped here:

http://www.instructables.com/id/Modify-The-HC-05-Bluetooth-Module-Defaults-Using-A/step3/Steps-To-Switch-The-HC-05-Into-Command-Mode/

Disconnect the Usb Cable Right? Disconnect RED cable form HC-05 right? Connect the Usb Cable, Right?

Here the dude, unpair from any device right? (no device paired at this moment right?)

other dude:

Connect Arduino VCC cable, RED Cable right? (Not Disconnected the USB Cable?) right?

i connect to Arduino with SERIAL MONITOR to com7, it connect, i type: AT and click on Send button, not happen anythink, not answer an OK.

Wich is wrong?

Thanks for your help....

ThanksThanks....

Finally i can send AT commands from Arduino Serial Monitor here the program that i loaded:
The answers for all my Questions are YES,

Disconnect the Usb Cable Right?
Disconnect RED cable form HC-05 right?
Connect the Usb Cable, Right?

Here the dude, unpair from any device right? (no device paired at this moment right?)

 #include <SoftwareSerial.h>

 SoftwareSerial BTSerial(10, 11); // RX | TX

 void setup()
 {
   pinMode(9, OUTPUT);  // this pin will pull the HC-05 pin 34 (key pin) HIGH to switch module to AT mode
   digitalWrite(9, HIGH);
   Serial.begin(9600);
   Serial.println("Hecho por JAK.....");
   Serial.println("Enter AT commands:");
//   BTSerial.begin(38400);  // HC-05 default speed in AT command more
   BTSerial.begin(9600);  // HC-05 default speed in AT command more
 }

 void loop()
 {

   // Keep reading from HC-05 and send to Arduino Serial Monitor
   if (BTSerial.available())
     Serial.write(BTSerial.read());

   // Keep reading from Arduino Serial Monitor and send to HC-05
   if (Serial.available())
     BTSerial.write(Serial.read());
 }

Serial Monitor display:

Hecho por JAK…
Enter AT commands:

i downloaded on my Samsung S3 Bluetooth Terminal, i can connect to my device (before i pair my device with the HC-05 on Configuration phone), but never of never say:

Hecho por JAK…
Enter AT commands:

why? wich program for my android recommend me to install?
why not display any message when i connect to Bluetooth?
remeber with Arduino Serial Monitor i can test AT commands.

Thanks

I can't make sense of the parts of your post with the word "font" in them. Can you rewrite them in plain text.

Alas, it was not just the strange font command that were confusing me.

If I understand this correctly (and I may not) the "Hecho por ..." stuff appears correctly on the Serial Monitor but does not appear on your Samsung.

As far as I can see that is because it is produced by Serial.print() which is the command to send text to your PC, not to your Samsung.

Have you got Bluetooth on your PC? If so I suggest you forget about the phone for a while and open a terminal on your PC connected to its bluetooth transceiver. Then you can see both ends of the conversation on your PC - in the Arduino Serial Monitor and in the terminal connected to the Bluetooth device.

I also strongly suggest that you figure out how to send ordinary text using Bluetooth before you experiment with AT commands which might upset the settings.

I followed this instructable without any problem
