56<H2>Description</H2>
57<p>
58This function registers a GGID to search for other units executing chance encounter communications, and sets data to be exchanged.<br />The WXC library uses the GGID registered using this function to search for other units executing chance encounter communications and automatically exchanges data.<br />You can use the <code><a href="WXC_SetInitialData.html">WXC_SetInitialData</a></code> function to reconfigure the data set by this function.

61<H2>Note</H2>
62<p>
63The WXC library does not use the beacon's GGID value that is assigned by the MP communication parent. The value used has special bits (WXC_GGID_COMMON_BIT: 0x80000000) added to the GGID that indicate common chance encounter communications.<a href="../../romfiles/wmtesttool.html">Note this point when monitoring actual radio wave status using <CODE><a href="../../romfiles/wmtesttool.html">WmTestTool</a></CODE>.</p>
