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

I can't help you with such information. Could you share your output and the code please?

Thanks for replying I was just playing with AT commands using 'minicom' serial program :) Further investigation led the conclusion that firmware doesnt support DTMF. Any suggestions in that area ? regards

Ok! I can't help you, I've never used this before
