I can't receive from ESP8266 - wifi

Question

I am using ESP8266 with STM32F103. The ESP receives the AT-command correctly and executes it, and I can receive the echo characters, but when it comes to the ESP response I can't receive anything.
Here is a pic to demonstrate the issue:

For instance: I send ATE0 to stop the echo, the ESP executes the command and there is no echo anymore, but I can't receive "OK" or "WIFI CONNECTED" or any other response.
I have tried putty and it worked without any problems in sending or receiving, so the ESP is fine.
I am using 115200 Baud rate, and this is my code:
main:
void main(void)
{
/* Init RCC */
RCC_voidInitSysClock();
/* Enable Clock For GPIOA & UART1 */
RCC_voidEnableClock(RCC_APB2,GPIOA_BUS);
RCC_voidEnableClock(RCC_APB2,14);
/* Set TX and Rx Directions */
MGPIO_voidSetPinDirection(GPIOA, PIN9 ,OUTPUT_SPEED_2MHZ_AFPP); /* TX */
MGPIO_voidSetPinDirection(GPIOA, PIN10 ,INPUT_FLOATING); /* RX */
/* Set Direction For Pin 0 To power Led */
MGPIO_voidSetPinDirection(GPIOA, PIN0 ,OUTPUT_SPEED_10MHZ_PP);
/* Enable UART1 Interrupt */
MNVIC_voidEnableInterrupt(USART1_ID);
/* Init UART1 */
MUART_voidInit();
/* Init ESP */
HESP_voidInit();
/* Connect To WIFI Network */
HESP_voidConnecttoWifi("Androidap","111112222");
//HESP_voidConnectToServerTCP("162.253.155.226","80");
//HESP_u8ReceiveResponse("Abdullaharm.freevar.com/status.txt","47");
while(1)
{
}
}
Implementation of ESP_init and connect to WIFI functions:
void HESP_voidInit(void)
{
//MUART_voidTransmitSynch("AT\r\n");
/* Stop Echo */
MUART_voidTransmitSynch("ATE0\r\n");
/* Set Station Mode */
MUART_voidTransmitSynch("AT+CWMODE=1\r\n");
MSYSTICK_voidSetBusyWait(1000);//microseconds
}
void HESP_voidConnecttoWifi(uint8* Copy_u8SSID , uint8* Copy_u8Pass)
{
/* Connect to WIFI network */
MUART_voidTransmitSynch("AT+CWJAP_CUR=\"");
MUART_voidTransmitSynch(Copy_u8SSID);
MUART_voidTransmitSynch("\",\"");
MUART_voidTransmitSynch(Copy_u8Pass);
MUART_voidTransmitSynch("\"\r\n");
}
Implementaion of UART_TransmitSynch:
void MUART_voidTransmitSynch(uint8 arr[])
{
uint8 i=0;
while(arr[i] != '\0')
{
UART1 -> DR = arr[i];
/* wait till transmission is complete */
while (!(UART1->SR & (1<<6)));
i++;
MSYSTICK_voidSetBusyWait(2000); //microseconds
}
}
I am using interrupt to receive from the ESP and this is the code inside ISR:
void USART1_IRQHandler(void)
{
if(GET_BIT(UART1 -> SR , 5))
{
static uint8 Data_Counter=0;
if(UART1 -> DR !='\0')
{
Data_Received_int[Data_Counter]=UART1 -> DR;
Data_Counter++;
}
else
{
Data_Counter=0;
}
CLR_BIT(UART1 -> SR , 5);
}
//UART_CallBackPtr();
}
