I'm trying to write a decoder using this as a guide. However, I find that the QR codes have 507 bytes, but there are 494 bytes in the struct. I'm trying to find which bytes to remove so I get the right data to decode.
EDIT
Found the issue. Using ZXing for decoding. The getRawBytes() returns the 3 header Bytes, and shifted everything to the left by 4 bits. Shifted them back, and now its de-meme'd.
