REPLIES FROM THE SMC-520
The sensor will reply with a confirmation when the command is accepted in the format as
$upians,1
where the three first letters are identical to the command and the three last letters in the identifier
are replaced with “ans”.
In case the command is not accepted the sensor will reply with
$ans cmd error
. In case of a problem
to store the information to the built-in flash memory of the sensor the device will reply with
$ans
mem err
. If a parameter is set outside the available range the sensor will return the message
$ans
range err
.
