dtmf #13

Detection of DTMF tones in my SIM800L module.

I get "OK" when I send 'AT+DDET=1,1000,1,1* ' over uart . But it doesnt seem to detect anything afterwards. Perhaps I am doing something wrong. Would be great to get some feedback.

regards Atul ref : *SIM800 Series_AT Command Manual_V1.09

hello. please update your module and try again. I don't have any module to test.

my operator doesnt seem to support Dtmf properly. Regards
