WL1835MOD + wpa_supplicant+DBUS - WEP security is not successful

Hi Johncy,

First lets try to connect directly to a WEP40 AP (not using DBus) so we can rule out any DBus issues.
Please follow the instructions in this link: processors.wiki.ti.com/.../Connect_to_Secure_AP_using_WPA_Supplicant and confirm if you are able to connect.

Regards,
Gigi Joseph.

Hi Gigi,

I am able to connect via command line.
The scan results using wpa_cli shows the security type as WEP. But when I use dbus in code to scan and the scan results shows CCMP or TKIP for WPA-PSK/WPA2-PSK. The group levels seems to be correct for the AP's with security type WPA-PSK/WPA2-PSK. But for WEP it shows empty string.

Regards,
Johncy.

Hi Johncy,

What does the "dbus-monitor" reveal?
Is it a problem with your app?

Regards,
Gigi Joseph.

Hi Gigi,

I use print_message function from dbus-print-message.c . Whatever reply message received through fi.w1.wpa_supplicant1.BSS for the (WPA/RSN) properties is passed to print_message

Regards,
Johncy.

Hi Gigi,

dbus_monitor output either doesnt show the Group as WEP it shows empty strings

Hi Johncy,

Can you please a corresponding "iw wlan0 scan" results as well (along with the dbus-monitor output)?

Hi Johncy,

I don't see any WPA/RSN information in the "iw wlan0 scan" response as well...
Does the AP sent any RSN IE in the Beacon/Probe Rsp?

Regards,
Gigi Joseph.

For AP's with WPA-PSK/WPA2-PSK it sends the RSN/WPA IE.

I dont find anything additional in the configuration to make it visible. If I configure the same AP to WPA/WPA2 it shows the RSN/WPA IE.

Hi Johncy,

I am not sure how I can help you with the AP's configuration...
I think you can check for the AP's manual online.

Gigi Joseph.
