Can't connect to api.asksensors.com...

Post by imagination *-* » Fri Sep 18, 2020 12:07 pm

Hi,

I've been trying for hours but I just can't get connected to the server using the test codes given by asksensors for ESP8266.

Help please :cry:

This is the code:

Code: Select all

/*
Connect Arduino WiFi to AskSensors
* Description: This sketch connects the Arduino to AskSensors IoT Platform (https://asksensors.com) using an ESP8266 WiFi.
* Author: https://asksensors.com, 2018-2020
* github: https://github.com/asksensors/AskSensors-Arduino-WiFi
*/
#include <SoftwareSerial.h>


// serial config
#define RX 10
#define TX 11
SoftwareSerial AT(RX,TX);
// TODO: change user config
String ssid = "Galaxy s10e"; //Wifi SSID
String password = "james1234"; //Wifi Password
String apiKeyIn = "dx5JGwaidzyQjPnmANRiuGfqWnMNvXDw"; // API Key
String host = "api.asksensors.com"; // API host name
String port = "80"; // port
int AT_cmd_time;
boolean AT_cmd_result = false;


void setup() {
Serial.begin(9600);
// open serial
Serial.println("*****************************************************");
Serial.println("********** Program Start : Connect Arduino WiFi to AskSensors");
AT.begin(9600);
Serial.println("Initiate AT commands with ESP8266 ");
sendATcmd("AT",5,"OK");
sendATcmd("AT+CWMODE=1",5,"OK");
Serial.print("Connecting to WiFi:");
Serial.println(ssid);
sendATcmd("AT+CWJAP=\""+ ssid +"\",\""+ password +"\"",20,"OK");
}
void loop() {
// Create the URL for the request
String url = "GET /write/";
url += apiKeyIn;
url += "?module1=";
url += random(10, 100);
Serial.println("*****************************************************");
Serial.println("********** Open TCP connection ");
sendATcmd("AT+CIPMUX=1", 10, "OK");
sendATcmd("AT+CIPSTART=0, \"TCP\",\"" + host +"\"," + port, 20, "OK");
sendATcmd("AT+CIPSEND=0," + String(url.length() + 4), 10, ">");
Serial.print("********** requesting URL: ");
Serial.println(url);
AT.println(url);
delay(2000);
sendATcmd("AT+CIPCLOSE=0", 10, "OK");
Serial.println("********** Close TCP Connection ");
Serial.println("*****************************************************");
delay(20000); // delay
}
// sendATcmd
void sendATcmd(String AT_cmd, int AT_cmd_maxTime, char readReplay[]) {
Serial.print("AT command:");
Serial.println(AT_cmd);
while(AT_cmd_time < (AT_cmd_maxTime)) {
AT.println(AT_cmd);
if(AT.find(readReplay)) {
AT_cmd_result = true;
break;
}
AT_cmd_time++;
}
Serial.print("...Result:");
if(AT_cmd_result == true) {
Serial.println("DONE");
AT_cmd_time = 0;
}
if(AT_cmd_result == false) {
Serial.println("FAILED");
AT_cmd_time = 0;
}
AT_cmd_result = false;
}

This is the result,

I've tried with https://api.asksensors.com/write/
&
http://api.asksensors.com/
&
https://asksensors.com/api.asksensors/write/

Also when compiling & uploading have these warnings of which I do not know how to solve. I wonder if this is the root cause :?

Hi,

Please try to connect to another site for verifying wifi connection. Try also to send data to your sensor directly by using browser : https://api.asksensors.com/write/apiKeyIn?module1=value1

Thanks

Hi AskGuru,

I got this in my browser. I don't quite understand what it's supposed to do.

That's mean that your Apikey In is correct and your sensor has successfully received the value 'value1'.

The code on the Github has been tested many times and it's worked without problem. If your wifi ids are correct so the problem can only come from hardware.
