Bluetooth Audio communication over UART with CC2564 using linux

Other Parts Discussed in Thread: CC2564

Hi,

We are using Ti's CC2564 chipset based bluetooth module, we would like to increase the HCI UART baud rate to 4 Mbps. This is for audio streaming on HCI UART.
We see the baudrate being set to 115200 when used the default bts file. We would like to know if we should use an alternate firmware for this. Also any concerns in doing this (setting a higher baudrate) from an module reliability and performance point of view?
We have earlier tried using the I2S lines to send PCM data from linux without much success
  • Hi Gautam,

    The first HCI command in the .bts file is setting the device's baud rate. You can use the HCITester tool to open/edit the .bts file and change the baud rate to 4mbps.

    The CC2564 chipset and its modules (CC2564MODx) are capable of handling up to 4mbps baud rate. There should not be any concerns regarding the CC2564 reliability at this baud rate.

    Best regards,
    Vihang
