Hi, everyone. I have some problems with send my GPS data to IOT sap hana cloud. When I try to do this,I have Exit value 22. So, it means thatthe curl received the bad request(400 status), but data is correct. If I try to send message without Tiny library, I send data, but It is not GPS data. How can I send data without library Process, and use HttpClient for send my data or maybe I can send the data other option.
There is my code.
#include <TinyGPS.h>
#include <SoftwareSerial.h>
#include <Process.h>
#include <HttpClient.h>
SoftwareSerial gpsSerial(8, 7); // create gps sensor connection
TinyGPS gps; // create gps object
void setup() {
Bridge.begin();
Serial.begin(9600); // connect serial
gpsSerial.begin(9600); // connect gps sensor
}
float lat, lon;
void loop() {
GET_GPS();
}
void GET_GPS()
{
while (gpsSerial.available()) { // check for gps data
if (gps.encode(gpsSerial.read())) { // encode gps data
//lol+= char(gpsSerial.read());
//Serial.write(char(gpsSerial.read()));
gps.f_get_position(&lat, &lon);
Serial.print("lat: "); Serial.print(lat, 6); Serial.print(" "); // print latitude
Serial.print("lon: "); Serial.println(lon, 6); // print longitude*/
pushToCloud1(lat, lon);
}
}
}
void pushToCloud1(float Lot, float Lat)
{
