DTMF - I have a requirement to send multiple digits/characters in 1-2 seconds.
ATD;
OK
AT+vts=1
OK
If I need to send a sequence the following works
AT+vts=1+vts=2+vts=3. But takes some time for each digit.
I have a requirement, where we need to send something like this.
At+vts=**236716236781237821789329138923#. The number of character(s)/digits(s) to be sent is around 32-40.
can you please guide me how to I accomplish this. I saw there were a few blasts command, but no luck using those commands.
