Grizzly.ZWave.QRCode (grizzly v0.22.3) View Source
Z-Wave QR code This module handles Z-Wave QR codes that follow Silicon Labs Software Design Specification SDS13937 and SDS13944.
Link to this section Summary
Functions
Encode device information into Z-Wave QR Code format The output of this is either a 90 byte or 136 byte string that should be put into a QR Code. Z-Wave specifies that the 90-byte code (no UUID16) is made into a 29x29 pixel QR Code. The 136-byte* code (w/ UUID16) should be put into a 33x33 pixel QR Code. QR Codes should be encoded as type "text" with error correction "L". NOTE: SDS13937 has a mistake with the code length. It says 134 bytes, but the UUID16 encode has 2 extra bytes for presentation, so it should be 136.
