I need to get all the RFID readers connected on the ethernet, currently I have an application which connects to one reader at a time. Also the IP address for the reader needs to be specified for connection.
I am using Motorola FX9500 fixed RFID readers.
It supports DHCP, HTTPS, FTPS, SSH, HTTP, FTP, Telnet, SNMP and NTP, WS Discovery. I'm assigning a static IP to the reader from its configuration and the reader is connected to the LAN.
There's an application named PowerSession by Motorola in which the option to find all readers is present. Its tooltip says it discovers readers using WS discovery/RDMP.
Any idea regarding this approach?
Thanks.
WS Discovery is a scheme for using network multicast to interogate broad swatches of devices connected to a network. In essence you are blinding communicating with everything on the network in a way to get responses back from specific devices. Wikipedia has a simplified overview: https://en.wikipedia.org/wiki/WS-Discovery
The RDMP part is a service definition for RFID Readers ( https://msdn.microsoft.com/en-us/library/dd298713.aspx ). The idea being that using WS Discovery you might find all sorts of objects on the network that support web services but aren't necessarily RFID readers. In the response you get back from each device will be definitions of what type of services the device supports. In the case of these RFID readers, it should return RDMP content that effectively says, "Hey, I'm a RFID reader and here is some information about me."
