Hello to all, Our design is using STM32F042G6 MCU to implement STSW-STM32011 firmware interface based on STM32Cube which implements ISO7816 protocol for us to talk to smart card. Unfortunately it does not seem to move beyond ATR.Is our MCU we use not...

Thank you, we will try to do some more debugging on devkit with T=1 as that is currently not working with T=1 cards for some reason. Did you test mostly with GSM or JAVA or some other cards? Any hints on debugging this?

In our design we use F0 but we decided to test now with the STM32L0538-Discovery which is what AN4800 references and hoping T=1 would be supported there. But it looks like T=1 does not quite work there too (T=0 card seems to work ok.) Missing ST8024 ...

Yes, we have fixed the soldering card issue meanwhile and put in some card reader connector to test multiple cards. We have found cards that present themselves with T=0 protocol in ATR and those seem to work fine returning some response to commands. ...

We have this AN4800

Thanks Andrew! I made a small mistake, we have actually used FW example from note AN4800. Which mentions F0 directly though for some reason L0 is mentioned as the only one supporting T=1 protocol.So we are trying now a reference dev kit (with L0) to ...
