Howto:How to Read WLAN Traces on IP72

Activate WLAN Tracing with V8

WLAN tracing is activated by navigating to Diagnostics submenu, Tracing, and activating the WLAN checkbox.

It can also be activated by invoking

config add WLANMGR0 /xtrace
config write
reset

Deactivate trace with

config rem WLANMGR0 /xtrace
config write
reset

Activate WLAN Tracing with V7

From the command line:

activate WLAN trace with
config add WLANMGR0 /xtrace
config change ASCDEBUG0 /enable supp /enable wlan
config write
reset

Deactivate trace with

config rem WLANMGR0 /xtrace
config change ASCDEBUG0
config write
config activate

Fetching trace by HTTP

Activate WLAN trace and click on "Trace (continuous)".

Fetching trace by USB

Download USB utilities from http://download.innovaphone.com/. IP72.zip contains the IP72 USB driver (usbio.sys) and the usbload utility (usbload.exe). Place the IP72 in the USB cradle and ,ake sure IP72 is correctly recognized and installed by Windows OS. Activate WLAN Trace as described above.

Alternatively, if there is still no WLAN connection to the IP72, one can activate it through usbload:

>usbload
usbload 1.5 [09-60034]
user: admin
password: ****
$

Activate WLAN trace:

config add WLANMGR0 /xtrace
config change ASCDEBUG0 /enable supp /enable wlan
config write
reset

After reboot start continuous trace by invoking:

usbload login 
usbload clog /file log.txt

When done, interrupt the command by hitting CTLR-C. The trace is stored to file log.txt.
