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 USR-WIFI232-A/B/C evaluation
board for users to choose.
