We've developed a MIDlet for the Nokia 6131 NFC (Developer Edition) - writing data onto the NFC tag. The data was read out by a third party NFC device.
Everything worked well with firmware 5.11. When firmware was upgraded to 5.12 reading out data failed.
I've been searching a lot of Nokia sites for a changelog form firmware 5.11 to 5.12 - but I could not find any information (besides the fact that older firmware will not be available...)
Does anybody have information von the firmware changes from 5.11 to 5.12?
