SelectSensors:
Prior to reading sensors,
the sensor selection endpoint can be used to
specify the desired sensors to be read. For
a given chip type, sensor filters can be ap
-
plied such as an OCRSSI upper or lower bound
threshold, and enabling or disabling tempera-
ture sensor reads. The temperature filter
shoudl be enabled if the temperature sensor
is being read.
7.
ClearResultsFromBuffer:
Clear previous
data from the low-level buffers.
8.
Read a sensor:
After configuring the read
-
er settings and applying filters to select
the desired sensors to read, the reading
process can be initiated. The calibration
data is not needed for the OCRSSI sensor
measurement type and is set for zero (0)
read attempts. The OCRSSI control can
narrow the range of responding sensors
and which data is collected. The max/
min values from 31 to 1 allow all data to
be collected.
{
“calDataMaxReadAttempts”: 0,
“maxOcrsiiFilter”: 31,
“maxReadAttempts”: 5,
“minOcrsiiFilter”: 1,
“sensorType”: “OCRSSI”
}
After initiating a read, the reader takes an
indeterminate amount of time to finish its
read process. The asynchronous nature of
the read process causes the results of the
read to be retrieved from a different end
-
point, described later in this document.
Along with a general endpoint to read sen-
sors, there are also endpoints for explicitly
reading each sensor type.
