Hi,
I bought a QCC3031 "HY1002" bluetooth module (https://www.aliexpress.us/item/3256805281764019.html?gatewayAdapt=glo2usa4itemAdapt) that I am trying to use in a Kef X300A powered speaker.
The X300A has an analog "line in" input that is routed to a WM8782A ADC setup in slave mode. My plan was to replace the ADC with Bluetooth module. I got it to produce garbled sound via I2s. My issue seems to be clock timings for i2s. I need to emulate the configuration currently setup for the WM8782A. I loaded the Qualcomm ADK configuration tool for this purpose. I got the module up on the config tool via USB. The WM8782A is configured for the following.
WM8782A Config
-Slave mode, 128,192,256,384,512,768fs
-24 bit word length
-96khz fast sample rate
-audio mode I2s
When the WM8782A was in circuit I got MCLK = 24MHZ, BCLK=6MHZ and LRCLK=96KHZ.
My question is, can I get the QCC3031 to emulate the WM8782A using the Qualcomm ADK configuration tool? Unfortunately, I am out of my league when it comes to i2S programming. I see that an .xml file for configuration can be loaded. Does anyone have a configuration file that might work? I have schematics and info for both the X300A and the QCC3031 module.
Any help would be appreciated.
Gary
