- starting of multiple (10 times) transmission series (SENDPER 10)
- switching of RADAR mode for 60 seconds (LAUNCH RADAR)
- displaying of RADAR function results (RESULTS)
- sending of RESET command to the module
As the
”
SOFTLINK Configurator” application is continuously developed and improved, the screen previews of
NB-K430 module configuration forms can vary in time.

Remote setting of module parameters through the NB IoT back channel
NB-IoT network uses standard Internet Protocol (IP) that naturally enables data communication in
both direc-
tions
. The NB-K430 module can use bi-directional communication for setting of its parameters from so called
”back channel”
, that is (for the reason of saving battery) opened only during two second period after transmit-
ting of each message (INFO, TRAP, or RESPONSE). In this period the module’s receiver is switched on and the
module is able to receive message from remote server.
Messages in reverse direction can be used for setting of module parameters. As these
”setting messages”
are
also coded by NEP protocol, they have in fact same structure, as the messages transmitted by module (i.e. set of
NEP-coded individual variables inside UDP packet).
The first variable in each setting message is always
Message type
. Setting messages are always of
”SET”
type
(OiD 63 =
”1”
). This variable is followed by one or more variables, that are requested to change.
The NB-K430 module performs setting of requested parameters (update requested variables) and sends back a
message of the
”RESPONSE”
type (OiD 63 =
”4”
), that contains set of variables after requested update. The
message is addressed either to the IP-address of the server from which the SET request came, or to the preset IP
address of target server (depending on the setting of ”Reply” parameter by ”sreply” command).
Remote setting of parameters through the back channel can be used for setting of same parameters that can be
set by optical interface (because both systems work on the same principle). More details about the back channel
communication can be obtained from the producer upon request.
