bitcoin:... URIs not recognized in QR codes

[schildbach]

Can you provide an example QR Code?

[MarkusTeufelberger]

With and without message (which is not used).

Weirdly enough after a bit more testing, it seems that some other QR codes (e.g. generated by http://qrfree.kaywa.com/?l=1&s=8&d=bitcoin%3A1BitcoinEaterAddressDontSendf59kuE%3Flabel%3DBlackhole%26message%3DDo_not_send_stuff_here%26amount%3D123.45) in fact DO work as intended?!

The QR codes have a CR or LF encoded into the amount. This makes them invalid.

I am having a similar problem, although I don't think there is a CF or LF in the QR code. I am generating the QR code with https://pypi.python.org/pypi/qrencode, and doing test decoding using QtQR. I am using a sample URI (bitcoin:175tWpb8K1S7NmH4Zx6rewF9WQrcZv245W?amount=20.3&label=Luke-Jr) straight from the documentation (https://github.com/bitcoin/bips/blob/master/bip-0021.mediawiki). Attached is a QR code I am generating that is not working.

The log says: "AddressFormatException: Checksum does not validate". Double check the address.

[AndySchroder]

Sorry about that. I guess they have a bad example address in the documentation, which is weird. I thought I had tested it without a '?' or any optional keys after the bitcoin address, and it was working, but after double checking, it does not work that way either. If I try a different bitcoin address, everything works as expected.
