9.5.2. Using the ADC Converter
An AT command is available to use the ADC function.
The command is AT#ADC=1,2. The read value is expressed in mV.
Refer to Ref 1: LE910Cx AT Command User Guide for the full description of this function.
Using the Temperature Monitor Function
The Temperature Monitor supports temperature monitoring by providing periodic
temperature indications, to perform some functions in extreme conditions. When
properly set (see the #TEMPMON command in Ref 1: LE910Cx AT Command User Guide),
it raises a GPIO to High Logic level when the maximum temperature is reached.
GNSS Characteristics
Table 42 specifies the GNSS characteristics and expected performance. The values are
related to typical environment and conditions.
