The red and blue led are on constantly which seems strange. On my other modules the blue led is on only during a transmission.
In ESPlorer I can not connect at any baud rate, tested them all.
I appreciate the help I am a Newb with the ESP8266.

Go to the wiki above or anywhere you know and recheck your wiring

Thanks for the reply.
What exactly is "the wiring". I have seen conflicting post.
Are pull up resistors needed? They were not needed for the ESP-01.

For the esp-201 you need to connect gpio-15 to gnd, and ch_pd to 3.3v. Also xpd to rst if you want to use deep sleep. You can just use a directly connected wire, doesn't need to be a resistor. See
here, and this photo:
