Hi,
It´s a long time that i was trying to send data to Ubidots by SIM800L EVB module with example codes in Ubidots_arduino_GPRS library. But it didn´t work. I am not a programmer (that is a big problem 
) but i think that the issue is that library is for SIM900 module. So after that i found a code for sending data to Ubidots without library, just with AT commands, and it works! Problem is that to send data of 7 variables takes about 90 seconds, and it is really bad for my low-energy project. Can anyone please help with shorter code ? Or anyone know how to make example code MultiVariables working with SIM800L EVB?
There is code that i am using:
#include <SoftwareSerial.h>
#include <String.h>
SoftwareSerial mySerial(7, 8);
int value1;
int value2;
int value3;
int value4;
int value5;
int value6;
int value7;
String token = “// PLACE FOR YOUR TOKEN //”;
String id_value1 = “// PLACE FOR YOUR ID //”;
String id_value1 = “// PLACE FOR YOUR ID //”;
String id_value1 = “// PLACE FOR YOUR ID //”;
String id_value1 = “// PLACE FOR YOUR ID //”;
String id_value1 = “// PLACE FOR YOUR ID //”;
String id_value1 = “// PLACE FOR YOUR ID //”;
String id_value1 = “// PLACE FOR YOUR ID //”;
void setup()
{
mySerial.begin(19200);
Serial.begin(19200);
delay(10000);
}
void loop()
{
value1 = random(36, 39);
value2 = random(24, 30);
value3 = random(65, 75);
value4 = random(50, 60);
value5 = random(12, 13);
value6 = random(45, 48);
value7 = random(85, 87);
comunication_start();
send_value(value1, idvariable1);
send_value(value2, idvariable2);
send_value(value3, idvariable3);
send_value(value4, idvariable4);
send_value(value5, idvariable5);
send_value(value6, idvariable6);
send_value(value7, idvariable7);
comunication_end();
