Arduino Uno R3 + W5100: Using the sketch from Blynk Example, Blynk library is the most recent from GitHub. Programming Arduino via USB. The result is: despite the configuration as “connection type” ==> Ethernet, the device turns offline in Dashbord if I unplug the usb cable and/or I close the blynk-ser.bat script. So, the system becomes offline if without the usb connection. What can I do ? Many thanks in advance.
Personally, I’d suggest using the WiFi connection method instead of the ethernet connection method. I’d also suggest changing the hardware to a nodemcu or esp32 instead of the Arduino uno.
@rcgismondi I’ve turned your PM into a public post. Please don’t use PM’s in future.
If you’re using the blynk-ser.bat script then your sketch presumably has #include <BlynkSimpleStream.h> as the included Blynk connection library rather than…
I am using #include <BlynkSimpleStream.h>. Curious is that despite the option to ethernet as “connection type”, with an ethernet connection the dashboard becomes offline, but if the usb cable is installed and the script running, the dashboard turns online.
Dear Pete, you gave me some valuable insights about my project/sketch. I will study a bit more the libraries and language. If necessary, I will ask for help again. Many thanks.
