I've been playing with my new ESP-03's from electrodragon for a couple of days and I am tearing my hair out!
I've tried every baud rate and still can't get anything on a terminal that isn't rubbish!!
My trusty USB bub II thingy blew the other week so I'm using a raspberry pi to connect to the UART interface.
To invoke a terminal on the pi I first edited /etc/inittab to disable the serial console, then use:
All I get at any baud rate is gibberish with occasional control characters that clear the screen etc!!
I also tried to upload new firmware, also without success.
I've checked for soldering problems and tried most combinations of GPIO's to VCC/GND I can think of.

(photo shows my setup but don't worry about the connections shown - I tried all the versions listed in this thread and many more!)
Any bright ideas?
Thanks in advance
