Hi, I am using a NodeMCU (ESP8266) as a garage opener. When I come close to my garage, I automatically connect to the Wifi of my ESP and can open the garage by entering a webpage (which is an "app" on my iPhone.
This actually works rather well. However, the time to connect to the wifi varies from 1-100 seconds which can be a pain when I am already late.
When I open system settings on my iPhone, I can already see that the WiFi is connected to my iPhone but it sometimes takes a minute to fully connect and be visible in the top bar of my iPhone which is needed to open the garage.
- The design is build to never restart the ESP.
- The WiFi provides only the connection for the garage, no internet or anything else.
- We are only using this with a limited number of phones (2). So using a static IP for these phones would be no problem.
- The code has been written and uploaded using the Arduino IDE
Is anyone having an idea for a quick fix?
I provide my code below. It is rather messy but might help for clarification.
