SendandWaitforResponse doesn't work with TcpConnection

We got everything working over USB, but it is extremely slow (5 seconds per label). We were told that using TCP connection would be faster. So we tried that but can’t even get a response back now. Our ZPL contains ^RFR command to get TID and EPC value. All three print the ZPL, but only the USB connections returns the TID and EPC values. The USB connection works with InitTime = 2000, and MaxTime = 3000. Anything less and I get erratic results. I get no results back for either TCP connection even with InitTime = 5000 and MaxTime = 10000.

Submitting a new iOS application to App Store using the RFD8500 SDK


I'm on the process of submitting a new application to the Apple Store that uses the RFD8500 SDK. Apple has rejected the application because:

We are unable to post your app to the App Store at this time because your app has not been authorized by the accessory manufacturer to work with the MFi accessory.


RFID Web App On Android Using RhoElements

We have a web application that makes use of the RhoElements library using JavaScript. Currently this application is running on older Windows CE devices, using Enterprise Browser. Recently, we have moved to the Android based devices (MC3300R). We would like to connect to the same web applications, but they do not seem to function at all. I know, for the Windows devices, that we had to copy over the file "WTG_RFID_PLG.dll" to the device. I assume a similar step would be required on Android, but I am unable to find any instructions for how to accomplish this.

RFID - EPC and TID reading


I have a printer from a customer, model ZT410, I develop in C #, I would like to know if there is how to record an EPC when printing and after that read the TID of the label that was printed

I tried to look for some example, but I didn't find it

How to locate tags by barcode (EAN) instead of EPC


We are developing an app for a Zebra TC20 device in order to perform inventories (we use a handheld Zebra RFD8500 reader to read RFID tags).

We are interested in locating tags with the RFD8500 using only the barcode of the tags instead of the full EPC.

Example: suppose we have 3 tags:
- Tag 1 -> Barcode: 8433594013132 // EPC: 843359401313200001723799
- Tag 2 -> Barcode: 8433594013132 // EPC: 843359401313200001723158
- Tag 3 -> Barcode: 8433594013300 // EPC: 843359401330000001832435
