error libnfc.driver.acr122_usb Wrong reply #646
Comments
Possibly related to #666. lsusb
With #678 applied on top of 42de50f: LIBNFC_LOG_LEVEL=3

Please note that the device appears to be working just fine with However, shutting down the daemon doesn't seem to be "resetting" the device as it just goes into timeout upon relaunching, with the green LED stuck. |
I acquired another seemingly identical device, this time with a mini CD included. Here's the SDK that is provided: ACR122U_SDK.zip The problem is that this other device works just fine with #678 applied. I wonder whether we're dealing with a defective and/or fake chip batch... Alternatively, it could have different factory settings. On the device that is working the LED never turns on, on the other one it's red and turns to green when it detects an NFC tag. |
Is the mentioned error resolved? I'm experiencing the same issue. |
Same problem here. I've tried using my ACR122U on 4 diffirents OS, 2 different machines:
All with the same problem, "error libnfc.driver.acr122_usb Wrong reply" |
Update: I've bought a new one and I don't have the error anymore. Either the other guy sold me a fake or it was damaged. |
Could you send here a picture of the device's back, please? |
Interesting... in that case there may be no easy way to determine whether a specific reader is going to work. |
My non-working device's serial number begins with Now that I'm rereading the comments I realized @Gapoly's one is unclear. Back when I replied I assumed he meant the fake/defective had the same SN prefix. |
That's right, my reader with the problem is also the RR171-XX. This reader that he posted in the photo is not clear if it has the problem or if it was the one that worked, I got it with the same initial serial number to buy RR545-XX but it didn't I wanted to waste time, if I answer if this RR545 model works I would be grateful |
Please note that I have a working device also beginning with |
I just recently went back to NFC and I found the problem. Yes, I had a bad ACR then bought another one which works. The main problem is that I bought some Mifare Classic 1K Gen1 (bad product from aliexpress), you can't change UID on Gen1. I bought some Gen2 that works on Mifare Classic Tool only and it works, I can change the UID. I'm looking for some Mifare Classic 1K Gen2 that works with nfc-mfclassic. Not a lot of choice in Europe. |
