Hi everyone,
i bought the Arduino shield SIM7600CE-T 4G(LTE) and i'd like to know if this shield supports DTMF. Thanks for your help.
2021-11-20 18:10:54 Is there someone who can help me. Like a wrote before i bought the sim7600 shield for Arduino and i'm waiting to receive it. Do i need external DTMF decoder to decode DTMF tones or the audio decoder chip on board will do the job. I hope someone will answer. Thanks in advance. userHeadPic digame
