Each property
xxx
of the module can be read thanks to a method of type
get_xxxx()
, and
properties which are not read-only can be modified with the help of the
set_xxx()
method. For
more details regarding the used functions, refer to the API chapters.
Changing the module settings
When you want to modify the settings of a module, you only need to call the corresponding
set_xxx()
function. However, this modification is performed only in the random access memory
(RAM) of the module: if the module is restarted, the modifications are lost. To memorize them
persistently, it is necessary to ask the module to save its current configuration in its permanent
memory. To do so, use the
saveToFlash()
method. Inversely, it is possible to force the module to
forget its current settings by using the
revertFromFlash()
method. The short example below
allows you to modify the logical name of a module.
