بسم الله الرحمن الرحيم ٱللَّٰهُمَّ صَلِّ عَلَىٰ مُحَمَّدٍ وَعَلىٰ آلِ مُحَمَّدٍ Try using different pins other than Rx and Tx. I was having an issue of my hc-05 doesn't reply to AT commands. So I used following code,
Now instead of Tx and Rx use Arduino's pins 2 and 3. Now check AT commands, After configuring you may use Tx and Rx pins again.

Code:
#include <SoftwareSerial.h>
SoftwareSerial Bluetooth(2,3);
char c=' ';
void setup()
{
Serial.begin(9600);
Serial.println("ready");
Bluetooth.begin(38400);
}
void loop()
{
if(Bluetooth.available())
{
c=Bluetooth.read();
Serial.write(c);
}
if(Serial.available())
{
c=Serial.read();
Bluetooth.write(c);
}
