Hello,
The source code of our Android ST25 NFC Tap application is available on this page:
https://www.st.com/en/embedded-software/stsw-st25001.html
Go to the bottom of the page, there is a "Get Software" section. Choose STSW-ST25002, this is the Zip file containing the source code.
One note concerning your other message :
"Regarding this video I can't follow what you've done here because yo're usinh a me whacompletly diffrent app to set the fast transfer mode , The app which is linked and available on andriod playstore and on the st site doesnt have the features to upgrade the firmware and to chooose the fast transfer mode!!!!!"
The "Firmware update" menu is available in our latest application available on Google Play. To see it, you should firt tap the ST25DV tag present on your discovery kit (the red board) otherwise that's right that the menu doesn't contain this entry.
By the way, the firmware can now be put anywhere in the phone's memory. The latest application also contains a firmware embedded in the application that will be proposed when you click on "select Firmware file". If you select that, you don't need to pick a firmware in phone's memory. That's the easiest way to test the Firmware upgrade.
Regards
