CC2541 Bluetooth AT Commands not work for any Commands sended from Serial

Question

i bought the HM 10 Bluetooth controller (CC2541), i got connect on this device through Serial Bluetooth Terminal (Android App) with Serial BLE menu this method not requires any pass and "Connected" state is showed and the led on CC2541 is always HIGH now, but... any command sended from terminal or sended from serial arduino is not show and "AT+NAME" or "AT+NAME?" returns null everytimes, this is my code to run Bluetooth on Arduino Mega2560:

#include <SoftwareSerial.h>

SoftwareSerial mySerial(26, 27); // RX, TX

void setup()
{
  // Open serial communications and wait for port to open:
  Serial.begin(9600);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only
  }

  Serial.println("Goodnight moon!");

  delay(500);

  // set the data rate for the SoftwareSerial port
  mySerial.begin(9600);
  mySerial.print("Wake up wake up wake up wake up wake up! Wake up wake up wake up wake up wake up!");
}

void loop() // run over and over
{
  if (mySerial.available()) {
    String s = "";
    char c;
    while((c = mySerial.read()) != -1) {
      s += c;
      delay(10);
    }

    Serial.println("Received: " + s);
  }

  if (Serial.available()) {
    String s = "";
    char c;
    while((c = Serial.read()) != -1) {
      s += c;
      delay(10);
    }

    delay(10);

    Serial.println("Sent: " + s);

    mySerial.print(s);
  }
}

Example of output serial monitor:

Sent: AT+DEFAULT

Sent: AT+BAUD9600

Sent: AT+HELP

I never receive "Received" status...
