I have a question about Le field.
Under the case that if I don't know how many bytes to expect, is there any special value of Le to indicate this?

If you don't know how many bytes you will receive in the response, you can set Le to 00.

I have set the Le to 00, but it throws error code 6C 08. 08 is actually the bytes that would have been returned. What can I do to get the bytes back?

Just resend the APDU with 08 in Le.
