Transmission of DTMF tones

One thought on “Transmission of DTMF tones

  1. Q:

    My application operates with the transmission of DTMF tones; I can transmit tones, but I don’t receive them. 

     

    A:

    DTMF tones can be directly transmitted via the serial link (AT+VTS) but they cannot be decoded.  A DTMF decoder has to be inserted on application level, converting received audio signals in digital signals.

    The DTMF decoder feature will be availble on a future version of our new V2 modules (10.00.xx4).
