Re: Newbee: Very general question wrt iot usage of the esp

But I think the issue is that you are leaving the client opened, it should be close it and reconnect new client for each transmission.
Also, BTW, I see that you are sending all the 10 timestamps on the same line, you should at least add a separator such a comma or space between each.
Hi martinayotte; thanks for your feedback.
I know that I am missing commas or similar - these got lost during trial and error hunting....
Also, I am not sure about the closing issue, as I send packets of ten - and for each packet the last is received.....
Here is the entire code - I hope this helps to nail it down - thanks again:
Code: Select all

int GasCounter = 0; // counter; 1 equals 0,01 m3
int timestamp[loopmaxcount]; // time stamp array for sending batches of #[loopmaxcount] to server
// Instantiate a Bounce object
Bounce debouncer = Bounce();
void setup() {
Serial.begin(115200);
delay(10);
// prepare GPIO2
pinMode(REED_PIN, INPUT_PULLUP);
// connect to WiFi
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);

delay(500);
Serial.print(".");

return;
}
// This will send the data to the server
for(int x = 0;x < loopmaxcount; x++) { // send batch of timestamps server
client.println(timestamp[x]);
// client.println();
}

// Read all the lines of the reply from server and print them to Serial
