I assume the garbage is Chinese.

Actually not, when the chip boot ups it sends data at 75000 bps, which looks like:
ets Jan 8 2013,rst cause:2, boot mode:(3,6)

load 0x40100000, len 28816, room 16
tail 0
chksum 0xb0
load 0x3ffe8000, len 3008, room 8
tail 8
chksum 0xe5
load 0x3ffe8bc0, len 18160, room 0
tail 0
chksum 0x50
csum 0x50

and then switches to 9600 or 115200 depending on the firmware that has been setup.

GPIO15 Pulled LOW 1k resistor

I purchased a development board and had lots of issues once I tried to make it standalone. This is an aside, but if you are planning on putting this into deep sleep, IT MUST BE STANDALONE not sure whats going on with the development board, tried pulling GPIO2 HIGH and no joy (I hope I have saved someone some hassle)

I have had the 201 working for sometime and its brilliant. The latest ArduinoOTA is really easy to use, you just need to upgrade your flash 1MB will work, but 4MB flash is preferable.

Anyone else having any issues?
