EG915U-EU DTMF Detection Problem

IoT Modules LTE Standard Module
1

Hello there.

I am using an EG915U-EU and I want to detect DTMF tones during a call. AT+QTONEDET command responds "+CMR ERROR: 58 " code. Doesn’t this module supports DTMF detection? In auido application note v1.2 it says DTMF detection is supported by EG915U modules. Am I wrong?

My module firmware version is : EG915UEUABR02A05M08

Thanks.

For others looking for a solution, new firmware is needed.
