Use case 2 Sensor network, infrastructure, polled
Problem description: The same company as in Use case 1 has a number of other sensors that
they want to request data from at certain times. For instance, when the humidity rises above a
certain level based on the values from Use case 1, the server starts to request a number of other
properties from sensors rigged around the assembly hall.
Security: WPA2 PSK
Data delivery: Current values the most important.
Solution:
The OWSPA311g modules have their UDP Receiver activated and a UDP peer set to send data to
the server.
The server will request data from a specific sensor with a data packet that includes the sensor id
and the register of the sensor it wants data from. The data will be sent to all sensors with UDP
but only the sensor with the targeted id will respond.
Use case 3, Service access, ac-hoc
Problem description: A series of weather stations are established to continuously gather data.
The stations have access to the power grid but the sensors needs to be placed on high poles for
best data input. Every second week a maintenance guy will stop by every station to download
the gathered data. To save the maintenance guy from having to climb up to the sensors for
every station a wireless network is setup so that the data can be read from the ground via a
PDA.
Security: None
Data delivery: All values are important
Solution:
The weather station will use the OWSPA311g in an ac-hoc mode. The OWSPA311g will have an
ac-hoc network running and a TCP Listener active for incoming connections. When the values
need to be read, the PDA will connect to the ad-hoc network. The PDA will get an ip-address
via the built-in DHCP server in the OWSPA311g. Once the PDA has its ip-address it will connect
to the TCP port and send a request for data to the system controlling the OWSPA311g. The un-
derlying system will respond by sending the last week’s stored data.
8.5 Serial Connection
For details on how to set the specific serial communications protocol please see the specific se-
rial settings AT commands: AT*AMSIT Serial Interface Type and AT*AMRS RS-232 Settings.
RS232
The OWSPA311g can be used with an RS232 connection.
RS422
The OWSPA311g can be used with an RS422 connection.
For four-wire RS422 multi-drop, the following connection setup shall be used:
