”
Periode”
command serves for setting of broadcasting period of regular info messages. The value of the param-
eter is factory preset to 60 minutes. Current value can be checked by
”
periode”
command (without parameter).
Broadcasting period can be changed by entering of required number of minutes (theoretically up to 65535 minutes)
after
”
periode” command.
Example of displaying, and setting of broadcasting period:
cfg#periode
Periode is 60 min.
cfg#periode 120
Periode changed from 60 min. to 120 min.

The module broadcasts messages wrapped into UDP packets of Internet Protocol to the pre-configured
target
server
, where the remote reading application is running. Following commands are intended for setting of
target
server IP-address and target application port number
and for setting of the
name of communication
gateway
between the GSM operator network and Internet (so called ”APN” = Access Point Name).
IP-address of target server
can be pre-configured by using of
”server”
command. The address can be entered
in commonly used decimal format.
Example of setting of the target server IP address to ”92.89.162.105” value and follow-up checking of the setting:
cfg#server 92.89.162.105
Server changed from ’0.0.0.0’ to ’92.89.162.105’
cfg#
cfg#server
Server is : ’92.89.162.105’
cfg#
Number of UDP port
can be pre-configured by using of
”sport”
command. The UDP port number should
correspond with the remote reading application port number. Example of setting of UDP port number to value
”2000” and follow-up checking of the setting:
cfg#sport 2000
UDP port changed from 0 to 2000
cfg#sport
UDP port : 2000
cfg#
The
”sreply”
command can be used for specification of
back channel communication
settings (see paragraph
”
Setting of module parameters from remote computer by using of back channel”). In some NB-IoT networks/services
there is possible to send back channel messages only from different IP address, than preset standard IP address of
target server used for sending of INFO messages. If the setting is ”Reply to server : no”, the module reply to back
channel requests regularly - that means send answers to the address from which the request came. If the setting is
”Reply to server : yes”, the module always replies to the preset IP address of target server (see ”server” command
setting). For setting ”yes” use ”1” parameter, for setting ”no” use ”0” parameter of the command.
Example of setting back channel communication and follow-up checking of the setting:
cfg#sreply
Reply to server : no
cfg#sreply 1
Reply to server : yes
cfg#
If the GSM operator providing NB-IOT services transfers data from the modules to the IoT service provider through
the virtual network, the
name of the communication gateway
between GSM and Internet (Access Point Name
- APN) should be entered to the module configuration by using of
”apn”
command. APN is assigned by GSM
operator. Setting of APN can be deleted by entering of ”.” value (dot).
Example of setting of APN-name to ”cms.softlink” value:
NB-K430
