EC200A Digital audio interface problem

IoT Modules LTE Standard Module
1

Previously we used the EC2X modules, with a SLIC from Silabs which needs the PCM channel active all the time.
Our vendor upgraded us to the EC200AAU.
With EC2x the initialization we use is:
AT+QDAI=1,0,0,4,0,0,1,1
AT+QCFG=“pcmclk”,1
With the EC200AAU the channel is only active with a call in progress.
Could you help me?
Best regards

Hi @rsdamelio
I don’t quite understand your question, EC200A also supports AT+QDAI configuration command. Can you elaborate on that.
