ESP-C3-mini-1 QR code does not scan

[rjustice]

Hi,

For the ESP-C3-mini-1 SOC we would like to scan the QR code in order to identify each chip.

When we try and scan it we do not have any success, can you recommend software that we should use to scan it?

Thanks

Product photos on the internet show a DataMatrix code on the module, and it decodes as such when "inverted" so that the LASERed spots are dark and the bare metal is light.
No idea if this is specified anywhere by Espressif though.
