    Default invalid conversion from 'const char*' to 'const unsigned char*' [-fpermissive]

    Hi

    Please can anyone help me?
    i got this error.

    Fehler: invalid conversion from 'const char*' to 'const unsigned char*' [-fpermissive]
    transmit(ASIGN_ACOS_AID_DEC, 12);


    i have defined
    #define ASIGN_ACOS_AID_SIG "\x00\xA4\x04\x00\x07\xA0\x00\x00\x01\x18\x45\ x43"

    and
    ^
    transmit needs (const unsigned char *txBuffer, unsigned long txLength)

    how can i call transmit with ASIGN_ACOS_AID_SIG or how i must define ASIGN_ACOS_AID_SIG

    lg Chris

    You could cast or use a properly typed constant instead of a pre-processor macro.

    Cheers,
