+ Prompt (>)
The module provides readings of an internal power supply
voltage monitoring sensor (VCC) through the ‘V’ command.
The module returns an 8 bit character (one byte) indicating the
current power supply voltage level followed immediately by a
second character
which is the prompt (‘>’). The command can
be useful for battery power monitoring.
The VCC value increases with increased supply voltage in 30
mV/step. The power supply voltage is given by:
V = VCC(dec)*0.030 [V]
(example: VCC=0x68 equals 3.12 V)
‘X’
0x58
