HC-05 is in AT mode but not responding to any command

-

good evening,

like said in title, i'm not getting response hc-05 module when in @ mode.
pairing phone working. led on module indicating states correctly (at mode, paired, discovery).

i followed tutorial , used code provided there. wiring correct according said tutorial.

tutorial:
http://www.instructables.com/id/modify-the-hc-05-bluetooth-module-defaults-using-a/all/

wiring:


code:

#include <softwareserial.h>

softwareserial btserial(10, 11); // rx | tx

void setup()
{
  pinmode(9, output);  // pin pull hc-05 pin 34 (key pin) high switch module @ mode
  digitalwrite(9, high);
  serial.begin(9600);
  serial.println("enter @ commands:");
  btserial.begin(38400);  // hc-05 default speed in @ command more
}

void loop()
{

  // keep reading hc-05 , send arduino serial monitor
  if (btserial.available())
    serial.write(btserial.read());

  // keep reading arduino serial monitor , send hc-05
  if (serial.available())
    btserial.write(serial.read());
}

baudrate in serial monitor set correctly , new line set \r\n

after see "enter @ commands:" in serial monitor type at, send , nothing happens.

i tried use bluetooth in different project , failed configure module programatically, discovered source of evil module not responding @ commands , i'm trying figure out why.


thanks in advance help

second module tried didn't response aswell

hello, first post asking in forum patient if dont correctly   well, im trying make robot evades obstacles , uses interrupts in order distances. ive used flexitimer2 run void function each 5ms, problem whe try verify program says me there error in use of flexitimer.    code: [select] flexitimer2::set(1, 1.0/1000, rastreodistanciamin()); i copy code below, please can tell error , how solve it, ive been loking dont know do. thank you code: [select] #include <flexitimer2.h> #include <servo.h> //motor a int ena = 7; int in1=6; int in2 = 5; //motor b int in3=11; int in4=10; int enb=9; servo cabeza; //hc-sr04 device int echo = 13; int triger = 12; //it use hc-sr04 determine , return distance in front of him int calculodistancia(){   volatile int tiempo;   volatile int distancia;   digitalwrite(triger,low); /* por cuestión de estabilización del sensor*/   delaymicroseconds(5);   digitalwrite(triger, high); /* envío del pulso ultrasónico*/   delaymicroseconds(10);   tiem

LED Strip Code

i downloaded code. here have several single leds flashing music microphone. in project, instead of single rgb leds, have 5 rgb led strips. need change in code? led strip 10m supernight rgb strip cut 5 equal strips. // arduino pin numbers const int do_pin = 2; const int ao_pin = 0; int sound; int led1 = 8; int led2 = 9; int led3 = 10; int led4 = 11; int led5 = 12;   void setup() {   pinmode(do_pin, input);   pinmode(led1, output);   pinmode(led2, output);   pinmode(led3, output);   pinmode(led4, output);   pinmode(led5, output);   serial.begin(9600); }   void loop() {     if (sound > 31) {     digitalwrite(led1, high);   }     if (sound < 31) {     digitalwrite(led1, low);   }     if (sound > 35) {     digitalwrite(led2, high);   }     if (sound < 35) {     digitalwrite(led2, low);   }     if (sound > 40) {     digitalwrite(led3, high);   }     if (sound < 40) {     digitalwrite(led3, low);   }     if (sound > 45) {     digitalwrite(led4, high);   }     if
