After opening the Server TCP socket, the script prompts to enter „1‟ to
receive data. Enter „1‟ and proceed to step 6 below.
6.
Connect Laptop C, as shown in the figure
Enterprise Security Set-up
.
It should have proper security credentials to connect to the AP.
7.
A “ping
2
” can be issued from Laptop C to the Wi-Fi module to verify
connectivity through the AP.
8.
Exchanging data between the module and the Laptop (C)
a.
Open a client TCP socket on the Laptop C by typing the below
command in the command line:
TCP.exe c 2001 <Module’s IP address> 5001
The IP address of the module is displayed in the command window
in Laptop (D) where the Python script was invoked. A server
socket is already opened in the module by the Python script.
b.
The command line window in Laptop C will display three options: 1
(Send), 2 (Receive) and 3 (Exit). Enter „1‟ to send data to the Wi-
Fi module. On being prompted “Enter the string to be
transmitted”, type any string from the Keyboard. On pressing
“Enter” key on the keyboard, the data is sent from the Laptop(B)
to the module and the terminal displays it with the
AT+RSI_READ
message as shown in figure
Running of Python
Script WiFi_Enterprise_TLS.py
.
9.
HTTP server access: To access the HTTP server, the step #7 in section
Configuration and Test Procedure
should be used. The URL
http://<module‟s IP Address> should be opened in a browser in
Laptop C.
5.4
Evaluating EAP-TTLS, EAP-FAST and PEAP Modes
These modes can be evaluated using the Hyperterminal or Teraterm. The
same set-up as shown in the figure
Enterprise Security Set-up
can be
used.
1.
Run the radius server in the Laptop (D). Power up the module and
issue the following commands.
a.
at+rsi_opermode=2
This configures the EVB to function in client mode with
Enterprise Security. The module responds with “OK”.
b.
at+rsi_band=0
2
The module can respond to a ping request sent from a remote terminal. There is no
command to send a ping request from the module. This is true in all the modes-
Client, AP and Wi-Fi Direct.
