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:

Code: Select allFatal exception (0):
epc1=0x402191c5, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000

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!
