WM_GetLinkLevel

C Specification

#include <nitro/wm.h>

WMLinkLevel WM_GetLinkLevel( void );

Arguments

None.

Return Values

Returns the signal strength of the WMLinkLevel list type.

Description

This function gets the signal strength between the connected sides during wireless communications. If there is no other side to connect to, this function will show the weakest signal strength. The signal strength of the parent device will take on the lowest strength of all the connected child devices.

Note

When this function is called in the wired communication environment created by using the IS-NITRO-EMULATOR hardware, it always returns the weakest signal strength. This phenomenon is specific to the wired communication environment that is performed with the very weak radio field intensity, and due to the specifications of the devices used for development. It requires special attention to evaluate the return values of this function in such instances.
