Transmission interval study is started over always after 100 successful sleep/wake-up cycles and,
if the expected receiving slot (t
RX slot
) with enhanced overlap margin (t
overlap
) has been missed. In
latter case the package is considered to be lost.

E.g. In system with TX interval of 1 s, and with 300 ms (approx. 300B @ 9600 bps) transmission
time:
t
min
= 1000 ms
t
TX
=300 ms
t
marg
=125 ms + 60 ms = 185 ms
t
sleep
= 1000 ms − (125 ms + 60 ms) − 300 ms = 515 ms
t
RX slot, min
= 1000 ms – 185 ms = 815 ms
t
RX slot, max
= 1000 ms + 285 ms = 1285 ms
4.5 Restart
After startup the module can be restarted by issuing a SL command, upon which the module will
shut down all circuitry, and Reboot the CPU (see SL-list).
