HOST: Set the server address to send the data to. The target server must be
configured to accept the data.
NETWORK: Define network behavior of the cellular module. AUTO mode is
enabled by default and under most circumstances will work well. If required it is
possible to force the modem to only look for “CAT M1”, “NB IoT”, or “2G” service
instead of scanning for all network options. It is required to run “SIGNAL” option
after adjusting network settings. Contact Sensit for more information.
PROTOCOL: Set the cellular data communication protocol to the following
options:
“HTTP”: Transfers data using HTTP Post protocol constantly at interval
determined by the output data rate (ODR)
“MQTT”: Transfers data using MQTT publish constantly at interval determined
by the output data rate (ODR)
“PERIODIC”: Buffers data according to the “RATIO” setting at the output data
rate. After the required number of samples has been collected the
modem will turn on, post all data, and then turn off. The interval of
cellular cycles is determined by “ODR” x “RATIO”
RATIO:
Set the number of required samples between cellular cycles for the
“PERIODIC” cellular protocol. This value also influences GPS signal acquisition
interval for certain modes. See information of GPS for more info.
SIGNAL: Acquire cellular signal strength and network registration status. This
option also programs the modem with any changes to the NETWORK mode. After
10-15 seconds the serial terminal should display “CSQ: X,Y CREG Status: Z”. A
description of X,Y, and Z follow below.
X: (0-31,99) defines the signal strength
Y: (0-7, 99) defines the data error rate
Z: (0-5) defines the network registration status
