Evaluating EAP-TLS Mode
To verify the EAP-TLS mode, a security certificate file should be loaded into the
module. A Python based flow is provided to verify this mode as loading of
certificate files cannot be done through Hyper-terminal or Teraterm.
1.
Enable WPA2-Enterprise in the Access Point settings and start the
Radius Server in the Laptop (D) connected to the AP.
2.
Install Python on PC(P). The “pyserial” package should be included in
the installation to access the serial port.
3.
Configure the EVB in UART mode, connect a UART cable between the
PC and the EVB and power up the EVB.
4.
Make sure the following things are configured accordingly in the
Python script
RS.WSC.x.x.GENR.x.x.x.x.x.x\Resources\UART\Python\WiFi_Enterpris
e_TLS.py
a.
Path of the certificate file
[
f3=open(“<Path>
\\RS.WSC.x.x.GENR.x.x.x.x.x.x\\Resources\
\Applications\\Radius_server\\raddb\\certs\\wifiuser.pem”,’r
+’
)
]
b.
SSID of the Access Point at
rsi_ssid
. It should reflect the SSID
of the AP you want to connect to.
c.
Values for parameters
user_identity
and
security_key
should
match the values in the file
<radius server path>\raddb\users
d.
Parameter
oper_mode
should be „2‟
e.
COM port name (called
param1
in the script) should match the
name of the COM port name in PC.
f.
rsi_band
should be configured according to the settings of the
AP.
5.
Open Windows Command Line in the PC (P) and run the script
WiFi_Enterprise_TLS.py
. Power cycle or reset the module before every
fresh run of the script.
The script sends AT commands to the module from the PC and makes
the module connect to the Access Point. The sequence of commands
executed in the script is shown below.
NOTE: It is strongly recommended that the user downloads the latest software
package inside
www.redpinesignals.com/OpenKM
(inside Wi-Fi
Modules/WiSeConnect/Software folder. The software package contains the latest
raddb folder and also the latest Python script that is used in this illustration.
