Other Parts Discussed in Thread: CC2564C
Hello Team,
we are working with the cc2564MOD Bluetooth module, we are able to load the init script (TIInit_6.7.16.bts) and able to pair,connect and play the songs through Uart by using A2DP profile.
We have configured the bluetooth as a slave and we are giving 3MHz BCLK with 48kbps sample rate. When we try to call using HFP protocol, we are getting audio with lot of noise. We have probed using oscilloscope at the audio pins we have observed that only on one channel we are able to see the data and on other channel we are unable to see the data.
After adding the below command in the script we are able to get the data on i2s.
Send_HCI_VS_Write_CODEC_Config 0xFD06, 0x0c00, 0x01, 0x0000bb80, 0x0001, 0x00, 0x00, 0x00, 0x0020, 0x0001, 0x00, 0x0020, 0x0001, 0x01, 0x40, 0x0000, 0x0000, 0x00, 0x0000, 0x0000, 0x01, 0x00
Wait_HCI_Command_Complete_VS_Write_CODEC_Config_Event 5000, 0x00, 0xfd06, 0x00
below i attached the oscilloscope images.
Could you help us in sorting out this issue.
Thanks & Regards,
