Hello,

I am using gsm module to transmit a message using USART of stm32f303. I have used following commands for gsmAT+CMGF=1AT+CMGS=''+923046761738''at the end it requires CTRL+Z to send the message but usart is not sending the ctrl+z i am attacting my code please help me''char configuration[150];char configuration[]=''AT+CMGF=1\r\n\0'';char message[150];void RCC_Configuration(void){  /* Enable GPIO clock */  RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA, ENABLE);   /* Enable USART clock */  RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1, ENABLE);} /**************************************************************************************/  void GPIO_Configuration(void){  GPIO_InitTypeDef GPIO_InitStructure;   /* Connect PA9 to USART1_Tx */  GPIO_PinAFConfig(GPIOA, GPIO_PinSource9, GPIO_AF_7);   /* Connect PA10 to USART1_Rx */  GPIO_PinAFConfig(GPIOA, GPIO_PinSource10, GPIO_AF_7);   /* Configure USART Tx as alternate function push-pull */  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_2MHz;  GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;  GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP;  GPIO_Init(GPIOA, &GPIO_InitStructure);   /* Configure USART Rx as alternate function push-pull */  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;  GPIO_Init(GPIOA, &GPIO_InitStructure);} /**************************************************************************************/ void USART1_Configuration(void){  USART_InitTypeDef USART_InitStructure;   /* USART resources configuration (Clock, GPIO pins and USART registers) ----*/  /* USART configured as follow:        - BaudRate = 9600 baud        - Word Length = 8 Bits        - One Stop Bit        - No parity        - Hardware flow control disabled (RTS and CTS signals)        - Receive and transmit enabled  */  USART_InitStructure.USART_BaudRate = 115200;  USART_InitStructure.USART_WordLength = USART_WordLength_8b;  USART_InitStructure.USART_StopBits = USART_StopBits_1;  USART_InitStructure.USART_Parity = USART_Parity_No;  USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;  USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;   /* USART configuration */  USART_Init(USART1, &USART_InitStructure);   /* Enable USART */  USART_Cmd(USART1, ENABLE);}void gsm_message(char *ptr){  while(*ptr) { while(USART_GetFlagStatus(USART1, USART_FLAG_TXE) == RESET); // Wait for Empty USART_SendData(USART1, *ptr); ptr++; } }int main(void){   //   RCC_Configuration();    GPIO_Configuration();    USART1_Configuration();    //while(1)  //{ gsm_message(''AT+CMGF=1\r\n''); //Delay(1); gsm_message(''AT+CMGS=\''+923046761738\''\r\n''); //Delay(10); gsm_message(''hello''); while(USART_GetFlagStatus(USART1, USART_FLAG_TXE) == RESET); // Wait for Empty    USART_SendData(USART1,(char)0x1A); gsm_message(''\r\n''); //Delay(10);     //}    while(1); // Don't want to exit} #i2c #stm32f303vct6 #stm32f3
