In order to test the communication between serial and WIFI network, we need to
connect the serial port to PC, and also connect WIFI network to PC. Due to the special
need both WIFI and serial, we connect and USB WIFI network Card as below, or you
could use laptop which has WIFI.
About the serial connection, because the module is 3.3V TTL level, the computer
cannot connect to it directly. Users need to use a TTL to RS232 adapter cable and then
connect to PC. In order to facilitate the test, we provide WIFI232 evaluation board for
