Abstract
A wireless communication method according to the present invention, in a Bluetooth device connected to multiple piconets and operating in a scatter mode, includes steps of (a) establishing credit values by link for the multiple piconets, and the total sum of the credit values by link as a temporary account value; (b) updating the credit values by link and the temporary account value every slot based on a predetermined manner; (c) performing communications through a link selected based on a comparison result of the credit values by link at each Presence Point(PP); and (d) unevenly redistributing predetermined credit values based on characteristics by link and returning to the step (b) in one of the two cases in which the communications are interrupted with a POLL_NULL sequence and the temporary account value becomes the same as the total number, n, of links.
