- Sat Nov 22, 2014 3:56 pm #3149 I'm totally new to this, i have some esp-03's if i understand correctly the only connection i need to make with the computer is over wifi to upgrade the firmware? is this correct? serial doesn't work? please help!

- Sat Nov 22, 2014 9:39 pm #3154 serial works. most here do upgrade over serial. search the forum or check the wiki for firmware upgrade. your module should have the required gpio to do fw upgrade over serial.

Read the second post in the thread... it contains a link to a zip with everything in it...
Worked for me on Win7 ... you might have to download the windows installer for Python27 if it reports a missing dll...

The compile ran perfectly after I fixed my path (be sure you modify your path to include all the required folders)...

believe me, that was the first thing I did... I've read the second post for several times, downloaded all the files, installed them as stated in that post, modified my %PATH%, double checked if all of the paths are proper and if necessary files are accessible from within any other folder and I still get this "Bad file number" error
