Hello I have been using the WifiEsp to send and receive data from Thingspeak. All is well until I put my http request on the Void Loop() section.

My Goal: I want to receive data every loop not on only on setup. Here is my code

#include <WiFiEsp.h>
#include <WiFiEspClient.h>
#include <SoftwareSerial.h>
SoftwareSerial Serial1(6, 7); // RX, TX
WiFiEspClient  client; 
int status = WL_IDLE_STATUS; 

#define SSID "Benok4G"      
#define PASS "password"
char reply;
char server[] = "";

void setup() {
// put your setup code here, to run once:
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to WPA SSID: ");
// Connect to WPA/WPA2 network
status = WiFi.begin(SSID, PASS);
Serial.println("You're connected to the network");


void loop() {
Serial.println("Receiving Data...");
if (client.connect(server, 80)) {
Serial.println("Connected to server");
client.println("GET /channels/344468/fields/3/last?key=ABCDEFGH 
client.println("Host: api.thingspeak.com");
client.println("Connection: close");

while (client.available()) {
char c = client.read();

if (!client.connected()) {
Serial.println("Disconnecting from server...");

I can receive the letter "a" properly. However, I want it too loop and give me updated value every loop.

enter image description here

BUT! when I put the code from the void setup() to the the void loop(). I get this error.. enter image description here

Any ideas on how can I loop it without getting the error? I tried adding delays and putting it on another function, still the same. It will only work when I put in inside the void setup()


  • @MarkSmith Thank you for pointing that out. I have posted my complete code. The code i posted is when I put the request in the loop and gives the timeout error. – Duckbenok Oct 15 '17 at 7:58
  • By "this error", do you mean the timeout? It looks to be working regardless... What's the actual problem? – Mark Smith Oct 15 '17 at 10:11
  • When I put it in the loop.I don't see the picture with OK response. It's just blank and sometimes it returns the one with square. Is this normal? – Duckbenok Oct 15 '17 at 17:01
  • Could it be that your setup() is taking too long to execute and is timing out? – Code Gorilla Oct 16 '17 at 14:37
