Hello, I am unable to scan the QR codes in the App on my Galaxy S7 Edge running Android 8.0.0. It appears that the app is not getting the correct aspect ratio or image size for the camera, as rotating the phone 90 degrees shows fairly large distortion to the image. I have attached images of screen …

There are some Xenons with corrupted data matrix, you should open a support ticket. See here [image] App can't scan Xenon Data Matrix BLE // NFC It appears that some Xenon stickers are missing a digit. If anyone cannot get the Xenon sticker to scan but can get other stick…

Hello, This did not appear to be this existing issue as my app is not generating an error at all, it is failing to scan the image in the first place. Additionally, I tested this on the Argon with the same results. Thanks

I think you need more light and to hold the camera closer to the sticker. QR codes can be decoded in any orientation since they have features to allow the decoder to find the orientation in software.

I have retested using the light from a bright microscope and still no luck. I was able to scan them in the same lighting conditions as my first images using a friends phone Google Pixel 2. [In-app%20horizontal%20wlight] [In-app%20vertical%20wlight]

What some others have done is to take a picture of the QR code using your camera. Either print that out in a larger format or have it ready on another screen enlarged a bit. Then go back through the setup process and scan the photo of the code instead of the actual code on the device. If that still …

I have been trying this as well as stretching the image to compensate for the apparent squishing seen in the app. In addition, I have edited the image attempting to create high contrast and decently sharp edges. I have scanned it enlarged on screen and printed with no luck. My friends Pixel 2 howeve…

@hollowayt9182 , on my Samsung A5 running Android 8.0.0, the application seems to take AT LEAST 15s to finally to a focus and grab of the label. If I am too close or moving too much, that fails and I have to start over. I have brought this up with Particle numerous times.

@hollowayt9182 @peekay123 if you have a moment, could you try scanning those same barcodes with your phones using this barcode scanner app from the ZXing team , and let me know how quickly you get a result? (Big bonus points if you try closing the app and scanning again a few times!)

@jensck_particle , on my Samsung A5 the app gets a clear focused view of the QR but takes several seconds to actually grab the image. When it does, it recognizes it every time. I found that if I am not at an “optimal” distance with the phone (not too close, not too far), then it “snaps” in just a f…

And I would recommend not running the device in the black, conductive foam it ships in. You should use a breadboard. The foam is mean to dissipate ESD during shipping. There is some discussion of that here:
