Hi,
After the upload of the WiFi scan test example for the ESP8266 in module 4.4. , the arduino IDE 1.8.9 shows an error:
“…
Wrote 272608 bytes (200033 compressed) at 0x00000000 in 17.9 seconds (effective 121.9 kbit/s)…
Hash of data verified.
Leaving…
Hard resetting via RTS pin…
Ongeldige bibliotheek gevonden in C:\Users\harry\Documents\Arduino\libraries\sketch_oct13a: no headers files (.h) found in C:\Users\harry\Documents\Arduino\libraries\sketch_oct13a
”
But – the program runs well on the target ESP8266 and shows the WIFI networks it found in the neigbourhood,
So, it did compile and load the program to the board.
But why do I get an error message?
I first thougth that there was something wrong, but the program seem to run well.
On the lower half of the Arduine IDE window the following message shows up repeatedly.
“Invalid library found in C:\Users\harry\Documents\Arduino\libraries\sketch_oct13a: no headers files (.h) found in C:\Users\harry\Documents\Arduino\libraries\sketch_oct13a”
It would be nice to get rid of it. Or what else is wrong?

Hi.
That’s probably just a warning and not an error message.
Try to update your ESP8266 boards version. Go to Tools > Boards > Boards Manager > ESP8266 and check your version.
Regards,
Sara

thanks for reaction. I noticed that the file sketch_oct13a in the libraries subdirectory was en empty template file. I deleted that file and the error disappeared .
