ESP8266 D1 Mini - Cloud login port

Need Help With My Project
22

Thanks Dmitriy.

Guess I’ll have to wait until I return home (to Melbourne) this weekend as I’ve a fast net connection (fibre-to-the-home).

I can’t test at my client’s site as they use WPA2 Enterprise (something the D1 mini doesn’t support).

I’ll update all with my weekend test to see if ms network latency was the issue.

Ok, back in Melbourne. Retested using my fast fibre-to-the-home internet connection. Connecting via IP didn’t work but via DNS name resolution did.

So here’s the output using blynk-cloud.com IP address:

void setup()
{
  Serial.begin(115200);
  Blynk.begin(auth, ssid, pass, "45.55.96.14"); // blynk-cloud.com = 45.55.96.14
}

And with this code variation (DNS resolution):

void setup()
{
  Serial.begin(115200);
  Blynk.begin(auth, ssid, pass);
}

the output looked like this:

I’m about to jump on a plane and head back to Canberra. So will check this forum in around 5-6 hrs and re-test from mobile hotspot.

Cheers,

You’re posting snippets of code that make it very difficult to see what values you’re assigning to variables, or if there are other things that may be tripping you up.
However, from what you’ve posted it seems that there’s a mismatch between the IP address that’s returned when you ping blynk-cloud.com and the one that you’ve specified in one of your code examples:

Pete.

Thanks Pete. Oops, typo-slip-up. While domain name vs IP address isn’t the objective of the test (getting my device to log in to blynk cloud service with the standard ‘getting started’ script is, so there’s no special vars or anything else tripping me up - refer to my previous posts), I’ll correct the IP address and re-test from my mobile phone hot-spot. Back in a sec …

Ok, re-tested (both IP and DNS name resolution). Clearly the latency to blynk’s server from my 4G mobile hotspot is too great. So I’m fat out-of-luck testing Blynk while I’m away from home and my fast connection / lower network latency.
