We are currently working with the EC200U module using its Open CPU firmware, and not the AT Commands. We have been trying to implement audio playback by storing an audio file in the firmware’s SDK path:
“\SDK\LTE01R03A06_C_SDK_U\components\ql-config\download\prepack”
To achieve this, we have made modifications to the audio_demo.c and audio_demo.h files in the example code, calling the stored audio file from these scripts. However, despite the log indicating that the audio file is being accessed (Audio file length 6 sec, audio start stop time stamp difference approx 6 sec), there is no physical audio output from the hardware. Need Support in resolving Audio Playback issue.
