I rubbed our Boron’s sticker with my thumb too much while using its buttons and am no longer able to scan the QR code in the Particle app or Android’s QR reader.
Do I have to request a replacement sticker from Particle, or does the code resolve to a value I have allowing me to print the QR code?
With particle identify any serial terminal program you can read the device ID, serial number and device secret by sending i to the device (in Listening Mode).
With these you can recreate the data matrix with this tool
Sorry this happened to you – we’re implementing stickers that have more robust resistance to corrosion in upcoming manufacturing runs. In the meantime, our support team can help you out.
To recreate the mobile data matrix, you will need the device’s serial number and it’s mobile secret.
particle identify does not provide the mobile secret at this time (perhaps it’s something we can do at a later date!).
You will want to open a serial connection with the device itself and go through the steps listed in Mesh device setup without QR code? to access the mobile secret as well. Using that, along with the serial number, will provide you with the data needed to regenerate the data matrix.
If you are continuing to have difficulties with this, do feel free to reach out to support, providing your device ID or serial number and we can assist on our end.
No worries! I’ve been meaning to drum up some internal discussions about supporting the secret on particle identify. It still fits our paradigm of needing physical device access, so it may be something we can see about in the future.
