ON
Data sent by the DTE is correctly received by the module.
2
Disabled
(AT&K0)
OFF
The first character sent by the DTE is lost, but it wakes up the UART (if disabled)
and the module (if in idle-mode) after ~20 ms. Recognition of subsequent characters
is guaranteed only after the complete wake-up of the UART and the module (i.e.
after ~20 ms).
Table 10: UART and power-saving summary
AT+UPSV=0: power saving disabled, fixed active-mode
The module does not enter idle-mode and the UART interface is enabled (data can be sent and
received): the CTS line is always held in the ON state after UART initialization. This is the default
configuration.
