Hi there,

I just bought your plugin and dit set it up in my template file.

With dummy data (short string) it works like a charm.
For real use I have JSON data being stored as a string with approx. 25K characters.

I wonder if its just a settings thing (playing around with a custom layout settings already) or if my string is simply too long for your QR-code generator?

I am acutally storing the JSON-data in an Advanced Custom field textarea field and retrieve it from there.
When replacing a real-life string with a short demo-string it works, but once again > as soon as I am using the string I need to output in QR-code with 25k characters it doesnt work.

Any advice?

Thanks
Hendrik

Hi,

QR Code specification has a limit of around 3Kb – that is 2953 8bit binary characters, 4296 alphanumeric characters (normal text) or 7089 numerical characters. If your content contains 16bit unicode characters, the limit is even lower. For normal text you can assume limit of between 3000 and 4000 characters on the safe side.
