How send AT Command in HM10 Bluetooth Module?

I buy two HM10 Bluetooth Module from Amazon

https://www.amazon.in/dp/B07DDPD229/ref=cm_sw_r_cp_apa_i_mfCQBbAX88T38

. I make connection with Arduino mega.

Vcc - 5V
Ground - Ground
11Pin of Arduino(TX) by voltage divider to RX of Bluetooth Module
10 Pin of Arduino(RX) to TX of Bluetooth Module

I select default baud rate of HM 10 Bluetooth Module is 9600. I upload this code

#include <SoftwareSerial.h>
#define RX 10
#define TX 11
SoftwareSerial HM10(RX,TX);

void setup() {
  HM10.begin(9600);
  Serial.begin(57600);
  while (!Serial) {
  HM10.println("Connect Serial Commnication");
  }
Serial.println("Goodnight moon!");
HM10.println("Hello, world?");
}

void loop() {
  if (HM10.available()) {
     delay(100);
    Serial.write(HM10.read());
  }
  while (Serial.available()) {
    HM10.write(Serial.read());
  }
}

in Arduino mega using smartphone with Arduino droid IDE and I hold reset button of Bluetooth Module. And power it . try to send AT command. I send "AT" but I not received any response I try again and again but I not received any response from Bluetooth Module. I watch many video in YouTube. I find I need to connect Enable pin to 5V I try again same process circuit is same only change I connect Enable pin to 5V and upload code again and when uploading is finished I hold reset button and power Bluetooth Module and try to send AT command I send again "AT" but no response from Bluetooth Module. When I try to send and received data from Smartphone using Bluetooth Module so it work correctly but it not respond in "AT" Command.I search many website in Google I found "BT05 is clone version of HM10" but I want to pair with two HM10 Bluetooth Module so I need to send "AT" Command but in my both HM 10 Bluetooth Module "AT" Command not respond.

So help me how I send "AT" Command in my Bluetooth Module or How I pair my two Bluetooth Module.

I believe the enable pin and the button are both redundant. HM-10 is in AT mode by default, and baud rate for config is 9600.

What I do for pairing two Bluetooth Module together?

Finally after many research I successfully Send AT command. I find problem in my Arduino nano board. If you face same problem so
you check this page.http://forum.arduino.cc/index.php?topic=434951.0

OMg.... thank you so much i have been going through a very stressful two days trying to figure out how to send at commands but it finally worked, feels good thank you.
