I've build several projects, using a NodeMCU (Esp8266) some years ago
Last month i've switched to another Internet provider and changed my internal Wifi network
Therefore its nessesary i re-program the NodeMCU to the new Wifi settings
But, even if i load the sketch and just Verify the sketch, at the end i get some "error" notifications i can't explaine ??
If i try to upload the sketch, at the and i've got several errors messages and a error saying that the program can't find the used COM Port ??
I already tryed to use other Virtual Com Port drivers, but no success
All my projects, using a Arduino Nano, Uno or a ESP32 i have modified to the new wifi parameters without any problems. Its Just the one using a NodeMCU (esp8266) that is causing the troublems.
Below the notifications after using Verify
No i also think its not a error, but something missing ??
The NodeMCU V3 (esp8266) are using a CH340G driver, but again... the problem appears already in Verify mode of the Arduino IDE
And the sketch has worked for more than 4 years without any problems
Its just i have to modify the Wifi Parameters in the sketch and upload again
Those don't indicate any problem at all. They indicate the code has successfully been compiled, and indicate how much of various resources it will consume. The messages that come after would indicate what the problem was with the upload, but you didn't share those.
Please don't post images of the error window like that. Copy the text and paste it into your forum post between code tags. Same goes for code and serial monitor output.
I'm not sure what those virtual COM port drivers are for in your case, but you must use a real COM port to upload an Arduino, so not surprising that they didn't work.
A virtual COM port driver would be used to fool an older app that it is sending data to, or receiving data from, a real COM port when in fact the data is going to, or coming from, elsewhere, for example a file, another app, or some remote server.
Have you selected the correct COM port for the NodeMCU? It should be the one that appears and disappears when you plug in and unplug the NodeMCU's USB cable.
If no new COM port appears when you plug in the NodeMCU then perhaps it had become faulty. In that case try other USB cables and USB sockets, or another Arduino using the same USB cable/socket. Also check the windows hardware information to see if it shows any faulty hardware or hardware without the correct driver.
@van_der_decken
Yes i know But where are these notifications comming from ?
And if i ignore them ans start to forward, than at the eind i get realy errors and a notification that the Com Port can't be found ??
They're coming from the compiler & linker, obviously. And they're perfectly normal statistics.
You keep saying you're getting an error, but you won't show us the error. I can't mind read, and neither can anyone else. There's nothing anyone can do for you.
