Specifying the number of tags/attempts for STOP_TRIGGER_TYPE in RFID3 SDK

STOP_TRIGGER_TYPE: has a number of useful types which make use of a timeout *and* a number of tags/attempts:

STOP_TRIGGER_TYPE_TAG_OBSERVATION_WITH_TIMEOUT, STOP_TRIGGER_TYPE_N_ATTEMPTS_WITH_TIMEOUT, STOP_TRIGGER_TYPE_ACCESS_N_ATTEMPTS_WITH_TIMEOUT

But — how do I specify the number of tags/attempts? Class StopTrigger has setDurationMilliSeconds, but doesn't seem to have a way to set the number of tags/attempts.

Reading EPC data

I'm trying to read both TID and EPC tag data using the MC3330R and the RFID3 SDK. I've encountered problems:

1. Is there a way to specify the memory bank to be read? There seems to be a "com.zebra.rfid.api3.MEMORY_BANK" class, but I can't see it used anywhere as a parameter.

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

Hello,

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:

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

Hello,

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

Hello,

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
