set sys launch_string <string>
This command sets the name of the application (indicated by <string>) that is launched
when GPIO9 toggles from high to low after power up (e.g., by pressing the FN button
on evaluation kits). You use this mechanism to invoke valid applications as shown in
Tabl e 2-7.
Setting the <string> to an invalid string such as test results in the following error mes-
sage when GPIO9 is toggled:
*test not Found*
Default: web_app
Example: set sys launch_string wps_app // Sets the launch application to WPS
2.3.51 set sys mask <mask>
This command sets the I/O port direction, where <mask> is a hex number referring to
a bit-mapped register. Figure 2-5 shows the bits corresponding to the GPIO pins and
Tabl e 2-8 shows the GPIO pin usage, their default state, and functionality.

TABLE 2-7: VALID APPLICATION STRINGS
<string> Description
web_app Launches the configuration web server.
wps_app Launches the WPS application.
Note: Do not set <string> to the configuration filename or the boot firmware
image. Otherwise, the module configuration may become corrupted and
the module will reboot.
Note: Disable this error message by setting the print level to zero using the set
sys print 0 command.
