I am programming using Wed IDE, after editing my code, It’s saying , “there is an error saving firmware”. What can be possible problems for this error. It shows device is online but not able to flash or save my code.
Hi @Vindhya,
Try copying your source code into a text editor on your computer (so it’s not lost), and refresh the page?
Also try putting your photon into safe mode, that can help when flashing new firmware as well.

Thanks,

i flash my code , and the photon starts breathing green instead cyan. Let be my code which i flashed before and got output or anything. what can be possible problem?
I tried flashing example codes too.
How did you flash new code while breathing green?
Breathing green means WiFi connected but Particle cloud ***dis***connected.
