I got the esp8266 and a 3.3v ftdi USB to serial cable and other bits from sparkfun in the mail today.
Hooked up 3.3v voltage regulator with an led to the 5v off the ftdi cable and checked that with a meter carefully. Then hooked up the esp8266 to serial and power.
So far the best command in the Mac shell I've found is:
`screen /dev/cu.usbserial-AJ02ZE2K 9600`
The slower 9600 is apparently common for later devices.
I also had to tie the non-gpio pins to 3.3v (reset and ch_pd). Now it prints a basic message when reset and also echos characters, but I'm pretty sure that it isn't understanding newline as gnu-screen is sending it, as it doesn't do anything besides return the cursor to the start of the line when I hit return.
[Vendor:www.ai-thinker.com Version:0.9.2.4]
ready
The little blue light flashes when I type, so I'm pretty sure the serial link is working other than "return". A good start, but I seem to be stuck on this issue currently. I can't seem to find anything that allows me to adjust what screen is sending for newline/carrage return. I'm guessing that because it's a Mac and it has a different idea about what should be sent for return versus an expected crlf set?
