how can i send the file form?

[kim-hyeonjun]

When you do Iridium satellite communication by sbdsend in the code above,i can only receive the first line above.

The above is a simple example, and to be exact, I want to call up the csv file stored on the sd card and save it in variable a and see it on my computer using Iridium satellite communication, but I can't receive the first line whenever I communicate. Can't we get an entry from iridium communication? Or I'd appreciate it if you could give me an answer. There is a code below.

`#include

define IridiumSerial Serial3

define DIAGNOSTICS false // Change this to see diagnostics

include

include

File myFile; int CS_PIN = 53 ; // CS pin String inputString; int count = 1; int i; // Declare the IridiumSBD object IridiumSBD modem(IridiumSerial);

void initializeSD() { Serial.println("Initializing SD card..."); pinMode(CS_PIN, OUTPUT); if (SD.begin()) { Serial.println("SD card is ready to use.");

} else { Serial.println("SD card initialization failed"); return; } } // =============================

void Read_Data() { myFile = SD.open("Sample.txt"); if (myFile) {

while (myFile.available()) {
 char Data = (char)myFile.read() ;
 inputString += Data; 
 count++;
// read file until no more
}
Serial.println("save OK!");
myFile.close();   // close the file:

} else { // if the file didn't open, print an error: Serial.println("error opening test.txt"); } } // =================

void setup() { int signalQuality = -1; int err;

// Start the console serial port Serial.begin(115200); while (!Serial);

pinMode(CS_PIN, OUTPUT); initializeSD(); // 1 단계 Read_Data() ; // 2 단계

i=count;

char h[i] = {0}; inputString.toCharArray(h,i);

Serial.println(h);

// Start the serial port connected to the satellite modem IridiumSerial.begin(19200);

// Begin satellite modem operation Serial.println("Starting modem..."); err = modem.begin(); if (err != ISBD_SUCCESS) { Serial.print("Begin failed: error "); Serial.println(err); if (err == ISBD_NO_MODEM_DETECTED) Serial.println("No modem detected: check wiring."); return; }

// Example: Print the firmware revision char version[12]; err = modem.getFirmwareVersion(version, sizeof(version)); if (err != ISBD_SUCCESS) { Serial.print("FirmwareVersion failed: error "); Serial.println(err); return; } Serial.print("Firmware Version is "); Serial.print(version); Serial.println(".");

// Example: Test the signal quality. // This returns a number between 0 and 5. // 2 or better is preferred. err = modem.getSignalQuality(signalQuality); if (err != ISBD_SUCCESS) { Serial.print("SignalQuality failed: error "); Serial.println(err); return; }

Serial.print("On a scale of 0 to 5, signal quality is currently "); Serial.print(signalQuality); Serial.println(".");

// Send the message Serial.print("Trying to send the message. This might take several minutes.\r\n"); err = modem.sendSBDText(h); if (err != ISBD_SUCCESS) { Serial.print("sendSBDText failed: error "); Serial.println(err); if (err == ISBD_SENDRECEIVE_TIMEOUT) Serial.println("Try again with a better view of the sky."); }

else { Serial.println("Hey, it worked!"); } }

void loop() { }

if DIAGNOSTICS

void ISBDConsoleCallback(IridiumSBD *device, char c) { Serial.write(c); }

void ISBDDiagsCallback(IridiumSBD *device, char c) { Serial.write(c); }

endif
