CC2564MODA: BTS-File can't change baudrate. Initialisation time out

Part Number: CC2564MODA

Good day to TI,

 

we have the following problem in our project, which uses "hciattach /dev/ttyUSB0 texas 115200 flow", i.e. BlueZ as the bluetooth stack, to attach the CC2564MODA BT-Chip:

Our BTS file with baudrate configured to 115200 does load and work normally, but if we change the baudrate to any other value (e.g. 230400 or 921600) it fails with a timeout on "Send_HCI_VS_Set_Supported_Features 0xFF26, 0x04, 0x06, 0x00".

 

The mentioned BTS file does work with BlueZ but our application seems to need some more bandwidth, because it gets a communication error on simultaneous Audio playback and Phonebook download when using some Smartphones that are more verbose on playback location feedback.

 

I attached the BTS textfile versions for the baudrates 115200 and 230400.

 

Thank you for your help.

 

Best regards.
