I have the long range integrated RFID reader - rs232 version. I used the configuration software to place the reader in "Answer" mode. I have tried using the Arduino sample to send the identify command to the reader, to no avail. I do not get a response when a tag is present.
I placed the reader back in "Active" mode, and connected it to the Arduino, and the sample program is receiving responses from the reader, when it reads a tag.
Ultimately, I would like to use a VB.NET program to query the reader, whenever I need to identify a tag. I am trying to build a system for a truck scale application. I can monitor the rs232 output from a scale indicator to detect whenever a truck pulls up on the scale. I then want to issue a command to the reader, to identify the tag on the truck windshield, to automate ticketing.
I have tried the following VB code, with the reader in answer mode, but it does not read tags.
