We are working on the HiDef Audio project that uses BM23 module connected directly to the digital audio codec.
We were able to get audio trough the Bluetooth, but with very bad quality. It sound like codec uses low speed connection, and you here high pitches being cut off.
We have purchased EVM board, and it sounds very good in the beginning.
However, when I made first patch file to re-flash it; is stopped to give me sound anymore.
The EEPROM tool sees correct IC. It is able to communicate, pair with BT device, and reload EEPROM over and over.
However, there is no activity on the I2S lines, doesn't meter it is master or slave.
Is there any suggestions, what do we need to try next?
