Description

In order to test WIFI module, we need connect module RS232 to PC and also WIFI to PC. In order

to test the communication between serial and WIFI network, we need to connect the serial port to

PC, and also connect WIFI networks to PC. Due to the special need both WIFI and serial, we use

PC which add USB WIFI network Card such as the following picture.

About the serial connection, because the module RS232 is 3.3V TTL level, the computer can not

connect to module directly, the user needs to have a TTL to RS232 adapter cable and then connect

to the computer. in order to facilitate the test, we provide WIFI232-B2 evaluation board for

users to choose.
