SIM800 + local server + failed connection

[PeteKnight]

It’s a different scenario - using Wi-Fi instead of SIM800 - but this code was developed to overcome exact the same issue.

Okay, here’s the code that I’ve been experimenting with recently, modified to use your sensors and virtual pins. The code expects a third display widget attached to pin V3, which will show how long (in seconds) your ESP device was awake for. Previously, the shortest wake time I was getting was around the the 5 second mark, when using Blynk.begin and an IP address assigned by DHCP. With this code I’m consistently getting wake times around the 1.2 second mark. This is without the two Dallas tem…

It might give a few pointers to get you started with Blynk.connect.
