I’m developing an android app that communicates with the SAT-CF device that came to replace the ECF (Tax Coupon Issuer).
However do not know how to start or how to do this, someone found some tutorial or can help me on how to work with SAT on android / java
Just one correction: the SAT did not come to replace the ECF, the SAT came to replace the source of income of the ECF manufacturers, because in practice, the NFC-e works very well without SAT in the other states. Back to the question, do you already know how to work with SAT on desktop? It would be essential to understand how to work with that gambiarra, I mean, technology, to then apply on android.
