    Hello,
    

    Currently I use an emStat pico module interfacing stm32f4 microcontroller. Initially, I tested to get firmware version of the module, then I get it correctly. Here is the initial results:
    

    EMSTAT_PICO Firmware Version: tespico1304#Oct 22 2021 14:3EMSTAT_PICO Firmware Version: tespico1304#Oct 22 2021 14:38:26
R*
    

    Then I try to send the MethodScript, I get "e!0009: Line 1, Col ", '\0' <repeats 29 times>" error. Do you have any suggestion to solve the problem? Here is my code:
    uint8_t firmware_version_response[36];
uint8_t response_buffer[50];
uint8_t firmware[2] = "t\n";
int isConnected = 0;

const char * dummy = "fs_dir /measurements\n";

void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
{
	HAL_UART_Receive_IT(&huart3, response_buffer, 5);
}


int main(void)
{

HAL_Init();
 SystemClock_Config();
 
 MX_USART2_UART_Init();
  MX_USART3_UART_Init();
  /* USER CODE BEGIN 2 */
  HAL_UART_Receive_IT(&huart3, firmware_version_response, 36);
  HAL_UART_Transmit(&huart3, firmware, 2, 0xffff);

while (1)
  {
  if(isConnected == 0)
    	  {
    		  if(strstr(firmware_version_response, "espico") != NULL)
    		  {
    			  uint8_t fresponse[] = "EMSTAT_PICO Firmware Version: ";
    			  HAL_UART_Transmit(&huart2, fresponse, sizeof(fresponse), 0xffff);
    			  HAL_UART_Transmit(&huart2, firmware_version_response, 36, 0xffff);
    			  isConnected = 1;
    			  HAL_UART_Transmit(&huart3, dummy, sizeof(dummy), 0xffff);
    		  }

    		  else
    		  {
    			  isConnected = 0;
    		  }
    	  }
    	  }
    	  }

        Hi AE104,
        

        This is a timeout error while waiting for a newline character. Either some data got lost in transmission, or the script is missing newlines. Are you giving the right size to your transmit function?
        

        Kind regards,
        Hielke

          Hi  

          Thank you for your response, here is my new results. So what is the problem with that?

          By the way here is my MethodScript that I sent:
          char const * sensor_data = "e\n"
"var c\n"
"var p\n"
"set_pgstat_mode 2\n"
"set_cr 100m\n"
"cell_on\n"
"meas_loop_lsv p c -1 1 10m 1\n"
"pck_start\n"
"pck_add p\n"
"pck_add c\n"
"pck_end\n"
"endloop\n"
"on_finished:\n"
"cell_off\n"
"\n";
          

          

          Here is the code callback and transmitting:
          void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
{
	HAL_UART_Receive_IT(&huart3, response_buffer, 40);
	HAL_UART_Transmit(&huart2, response_buffer, sizeof(response_buffer), 0xffff);
}


while (1)
  {
	  if(isConnected == 0)
	  {
		  if(strstr(firmware_version_response, "espico") != NULL)
		  {
			  uint8_t fresponse[] = "EMSTAT_PICO Firmware Version: ";
			  HAL_UART_Transmit(&huart2, fresponse, sizeof(fresponse), 0xffff);
			  HAL_UART_Transmit(&huart2, firmware_version_response, 36, 0xffff);
			  isConnected = 1;
			  HAL_UART_Transmit(&huart3, sensor_data, 151, 0xffff);
		  }

		  else
		  {
			  isConnected = 0;
		  }
	  }
	  }
