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

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 ?
