Help letting the device work
Posted: Fri Dec 05, 2014 2:32 pmHello,
I got the devices working before, but I cannot get them to work anymore. I need some help.
I have flashed the Cloud updating firmware:

I have had this firmware working before (but on a breadboard and I redid the wiring and it's not working anymore).
I am able to reflash the device, but when it powers it most of the time only outputs "nl|bl`". Sometimes I get this:
I have this on both of my modules (esp8266-01). Maybe I should also mention I am powering it through a lm1117 3v3 which gets 5v from a serial to usb adapter (I tried 2 of these adapters, same problem). I also have some capacitors connected to the main power lines...
Thanks!
