• To some extent, the cell monitoring command
AT^SMONC
covers the same parameters. The receiving level,
for example, can be queried with both commands. Yet the resulting values may be slightly different, even
though obtained over a time period of a few seconds. This is quite normal and nothing to worry about, as the
cell information is permanently updated.
• For compatibility with earlier products and to support legacy applications, any input character may be used to
stop the output in certain cases (depending on the settings of
AT+IPR
and
AT+CMUX
).
