How to generate QR code for matter devices ? Is there any tool to generate QR code image ? (CON-579)

[aggaddam]

I want to generate a QR code for the matter device. By default, all the device's discriminator values are 3840. I am overwriting default nsv data partition with the factory partition data with discriminator value 3001. I also want to generate a QR code along with the new factory partition with discriminator value 3001. Is there a tool we can use to generate QR code ?

Generating factory partition table with Discriminator 3001

cd esp-idf
source export.sh

cd esp-matter
source export.sh

The script generates factory_partition.bin.
python3 connectedhomeip/connectedhomeip/scripts/tools/generate_esp32_chip_factory_bin.py -d 3001

Flash it on the device.
esptool.py -p (PORT) write_flash 0x10000 factory_partition.bin

Here is the info that I want to generate QR code image
