So, I am trying to create a project with a sketch on the ESP8266 and the Blynk app on my iPhone that simply turns an LED on pin 7 of the NodeMCU ESP8266 board On and OFF.
From the examples.Blynk.cc page, I selected I have selected the
Connection: ESP8266 WiFi
Example: Blynk Blink
I have amended the code to reflect my SSID and password, and I have added the Auth token. So far so good!
Next, building the Blynk project on my iPhone. I created a new project, and added a button, assigned it to digital pin 7.
I have built the circuit with and LED across Pin7 and Gnd.
I have uploaded the sketch.
Now the issue - nothing happens. I see 'iPhone LED' (the name I gave my project) is offline.
What am I doing wrong please?
