Discrepancies in RFID Tag Reading/Writing API on Linux Debian 10

[Krishna-de]

I have implemented API in python[Python version: 3.7] The API performs flawlessly when running on a Windows OS, but I have observed inconsistent behaviour when it comes to the same API on Linux Debian 10.

Specifically, the primary issues I am facing are as follows:

Inconsistent EPCs: When running the API on Windows, the EPCs (Electronic Product Codes) for RFID tags consistently read as expected. However, on Linux Debian 10, I have noticed that the API occasionally produces different EPCs for the same tags.

Zero RSSI Values: Another issue I have encountered on Linux Debian 10 is that at times, the Received Signal Strength Indicator (RSSI) values for RFID tags are recorded as zero. This issue is particularly problematic as it affects our ability to accurately assess tag proximity and positioning.

I have reviewed the code and configurations, and as far as I can tell, there are no obvious differences in the way the API is implemented for the two platforms. However, it's evident that something is not working as expected on Linux Debian 10.

I would greatly appreciate it if you could provide some insights or guidance on potential reasons for these discrepancies and how we can address them.

Hello Krishna, This is a critical observation and I have sent this to our Software team. Most probably this is something to do with the shared object, I believe you are using the latest one. May I ask,

1. Are you using x86_64 processor. Can you elaborate your processor. They may ask for it.
2. Do you observe the same behavior in both Java and Python?

Thanks for letting us know about this critical bug. I will be in touch.

Regards, Mansur

1. I am using Intel Atom E3930 is a 64-bit processor [Simens Box PC]
2. I did not test with JAVA

Krishna, Thank you for the update. I will provide this info to our Software guys. Regards, Mansur.
