I have 3 NANO ESP32 boards that I am connecting to a PC using UDP. Everything was working last week but now all 3 boards show No Shield error from the WiFi.begin call.
Any ideas?
Welcome to the forum
What changed since last week ?
The answer is not "nothing"
For instance, have you updated any libraries or board definitions ?
I reloaded the program.
I have also run one of the examples for the UDP async - same error.
I think a lot of the ESP 32 libraries were updated but I;m not sure which ones.
Hello @anon14454047,
What board library version are you using for the Arduino ESP32 boards?
Are you using the example codes or a custom one?
