If you have previous code in the module that could be running (module will start default program 30 sec after initial boot up)

So be sure to either save and RUN an empty program to the module to make sure it is not busy trying to run previous program code or in your running code include an exit button to stop the module before you try and save the new code.

If your module is trying to run another program while you save a new program it could cause it to timeout.

just a possibility

Hi.
Yes, I think that this is the problem! My code isn´t so good and wait for a serial input, that cause it was running (and slowly) in the background.

Many thanks!

If I test a program with a few lines, it works ok, no problem.
But if I try to,, for example: copy paste a large basic files(125 lines... 2,5Kb) hang.
Same if you try to upload a basic files... hang..
