I use Arduino for ESP32pico with micropython.
. Transferring files (.py) from disc to target does not seem to function.
Can someone help here?
Are you using Arduino's App Lab or the normal IDE (e.g. IDE2.x or IDE1.x)?
What are the symptoms? Do you get any errors? Or does it simply not do what you expect it to do?
I moved your topic to a more appropriate forum category @karelvh.
In the future, when creating a topic please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.
As is clearly explained in its description, The Development Tools > App Lab category you chose is only to be used when the primary subject matter of your topic is Arduino App Lab. Since you are not using Arduino App Lab, it was inappropriate for you to chose that category for your topic.
Thanks in advance for your cooperation.
I use arduino lab app. But also usinf mpremte does not function well. I get OSerr36 (file name too long) though filename is short and so is the pathname
I do use Arduino app lab for Micropython version 0.21.0
The name of the development tool you are using is "Arduino Lab for MicroPython":
Despite the somewhat similar name, that is completely different from Arduino App Lab. Arduino App Lab is a development environment for the new Arduino UNO Q board.
sorry for the confusion.
