uart embedded wifi module

The Oolite_o1 is a low-power Wi-Fi connectivity module for the Internet of Everything. internal Alljoyn protocol.
The module support IEEE 802.11b/g/n protocol. The module includes a number of TCP/IP-based
connectivity protocols along with SSL,enabling a low-cost,low-complexity system to obtain
full-featured internet connectivity and reliable information exchange.
The module is based on QualcommAtheros QCA4004 which is highly integrated, and
includes an energy efficient on-board power amplifier and LNA.
The module provide two interfaces for connecting to local system controller. A UART-based
host interface can be used for rapid development and deployment of simple data streams between
the local device and the internet cloud. An SPI slave interface is available for applications that
require more advanced connectivity to the network.

CHIPSET QCA4004 has a 130Mhz xtensa CPU, 448K ram and 512K rom(extendable )

                                        1           The module bootup is under control of host
                                                     CPU via SPI slave interface.The external
                                                     CPU is required and the SPI interface is the
                                                     host interface.

                                                     Internal pull-up with 10kohm resistance.
                                                     If you want to use the SPI interface,pls ensure this pin is high when
