==XBee XSC

This is a higher power 900 MHz ISM band radio. Real life urban (San Francisco) range is 5 or 6 blocks with rubber duckies.

For the cyclic sleep thing to work you have to set up the other node as well:

<pre>
atsm0
atst10
atlh29
atht29
</pre>

In fact you don't really need the lh and ht settings on the
remote node, just the SM6 setting, because its peer will
never be asleep, and thus never needs a long initializer sent
at all.

the barrier to getting really low energy use is that you
apparently can't set the ST parameter (how long to stay awake
for before dropping into sleep mode) to less than 0x10 times
100ms, which is 1.6 seconds during which it draws 48mA!

Unfortunately, when in cyclic sleep mode you can ONLY enter
sleep by idling, as it ignores the sleep pin. :(
