wake up xbee through RF

Hi everyone,

I hope there is no similar topic, but I try search out in the forum but I got nothing. So here I am, I would like to know if it is possible to wake up a xbee module series 1 through RF. I read the datasheet and it says (http://ftp1.digi.com/support/documentation/90000982_E.pdf):

"Cyclic Sleep Remote with Pin Wake-up (SM = 5)

Use this mode to wake a sleeping remote module through either the RF interface or by the deassertion of Sleep_RQ for event-driven communications. "

After reading and searching forums I achieve to understand that while the xbee module is asleep, it cannot hear anything so if it has a incoming RF data it will just lost it, because it is asleep.

As you could guess I do not speak english correctly so I could misunderstand what I read. But maybe it is not, so I was wondering if anyone could help me to figure out how to wake a xbee through RF. By the way I am using API communications, just in case.

Again, I beg you pardon for my english.

Thank you,

bye!
