Functions
Generates an 11-digit manual pairing code.
Options
:discriminator— 12-bit discriminator (required, only top 4 bits used):passcode— 27-bit setup passcode (required):flow— commissioning flow, 0 = standard (default 0). When non-zero, the vid_pid_present bit is set.
Generates a Matter QR code payload string.
Options
:vendor_id— 16-bit vendor ID (required):product_id— 16-bit product ID (required):discriminator— 12-bit discriminator 0..4095 (required):passcode— 27-bit setup passcode (required):flow— commissioning flow, 0..3 (default 0 = standard):discovery— discovery capabilities bitmask (default 2 = BLE):version— payload version, 0..7 (default 0)
Raises ArgumentError if any value is out of range or the passcode is
