Note: When the ME is in Limited Service or IDLE mode with/without PDP context activated, the on/off time ratio
of the LED is always the same, no matter whether or not power saving is enabled. The only difference is that in
SLEEP mode the duration of the on/off periods is a multiple n of the equivalent periods without SLEEP mode.
The multiple n is synchronous to the active state of CTS during SLEEP mode (where CTS is set/reset every 0.9
- 2.7 seconds. See also
AT+CFUN
for the timing of CTS.
