hello everyone,when the card response I received, i immediately send a new command to card, but i find the third byte of command is always error.

The last command and new command is about 100us. If i add the time to 200us, the command is sent success. I don't know the driver have problem

or the sim module hardware have problem.Have you encountered this problem?
