I am currently working on a project that transfers data and saves it directly to google sheets, however most of the other projects utilizes boards like NodeMCU and ESP32. Can the ESP8266-01 WiFi Module do the same?
I tried using this code
#include <Arduino.h>
#include <ESP8266WiFi.h>
#include "HTTPSRedirect.h"
// Enter network credentials:
const char* ssid = "network";
const char* password = "password";
// Enter Google Script Deployment ID:
const char *GScriptId = "AKfycpwCtWuN3BNIO5CR9BtZJAMaRNUgusldcAz6V7rtGCg1L5srZ5iAEZumVeb- 1ea5Y6mg3Q";
// Enter command (insert_row or append_row) and your Google Sheets sheet name (default is Sheet1):
String payload_base = "{\"command\": \"insert_row\", \"sheet_name\": \"Sheet1\", \"values\": ";
String payload = "";
// Google Sheets setup (do not edit)
const char* host = "script.google.com";
const int httpsPort = 443;
const char* fingerprint = "";
String url = String("/macros/s/") + GScriptId + "/exec";
HTTPSRedirect* client = nullptr;
// Declare variables that will be published to Google Sheets
int value0 = 0;
int value1 = 0;
int value2 = 0;
void setup() {
Serial.begin(9600);
delay(10);
Serial.println('\n');
// Connect to WiFi
WiFi.begin(ssid, password);
Serial.print("Connecting to ");
Serial.print(ssid); Serial.println(" ...");
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.print(".");
}
Serial.println('\n');
Serial.println("Connection established!");
Serial.print("IP address:\t");
Serial.println(WiFi.localIP());
// Use HTTPSRedirect class to create a new TLS connection
client = new HTTPSRedirect(httpsPort);
client->setInsecure();
client->setPrintResponseBody(true);
client->setContentTypeHeader("application/json");
Serial.print("Connecting to ");
Serial.println(host);
// Try to connect for a maximum of 5 times
bool flag = false;
for (int i=0; i<5; i++){
int retval = client->connect(host, httpsPort);
if (retval == 1){
flag = true;
Serial.println("Connected");
break;
}
else
Serial.println("Connection failed. Retrying...");
}
if (!flag){
Serial.print("Could not connect to server: ");
Serial.println(host);
return;
}
delete client; // delete HTTPSRedirect object
client = nullptr; // delete HTTPSRedirect object
}
void loop() {
// create some fake data to publish
value0 ++;
value1 = random(0,1000);
value2 = random(0,100000);
static bool flag = false;
if (!flag){
client = new HTTPSRedirect(httpsPort);
client->setInsecure();
flag = true;
client->setPrintResponseBody(true);
client->setContentTypeHeader("application/json");
}
if (client != nullptr){
if (!client->connected()){
client->connect(host, httpsPort);
}
}
else{
Serial.println("Error creating client object!");
}
// Create json object string to send to Google Sheets
payload = payload_base + "\"" + value0 + "," + value1 + "," + value2 + "\"}";
// Publish data to Google Sheets
Serial.println("Publishing data...");
Serial.println(payload);
if(client->POST(url, host, payload)){
// do stuff here if publish was successful
}
else{
// do stuff here if publish was not successful
Serial.println("Error while connecting");
}
// a delay of several seconds is required before publishing again
delay(5000);
}
When I use this code it gives an error of invalid head of packet (0x00)
If there is already a code please do tell thank you for your time! (Please be merciful if I made a mistake im still new to this:)
