CCS/CC2640R2F: bidirectional audio example connection problem

Tool/software: Code Composer Studio

Hi,

Now I'm using the central_bidiractional_audio & peripheral_bidirectional_audio example on my custom board(CC2640R2F + TLV320AIC2304)

Sometimes the connection is disconnected irregularly.

I do not know why, but when disconnected, the missing rate tended to increase in the serial monitor.

Also the central device stops and does not automatically start at all.

I removed the macro I2S_DEBUG and fixed the errors in code in I2SCC26XX.c to decrease the probability of the disconnection, but the issue still remains after removing the macro.

Please let me know how to fix this or tell me if any updated version exists.

Thanks for your help in advance.
