DTMF Decoder

Hello, guys.

We are using SL series chips to develop eCall software.

Can the SL series chips receive and decode the DTMF tones using AT Commands?


Which SL module you are referring?

I think yes for SL6087.

May I know the AT Commands used for receiving DTMF?

For DTMF detection on SL6087, we can use +WDDM command.
Please refer to section 21.17 in AT command interface guide for info.

Hope it helps.
