CC2564CSTBTBLESW: CC2564C: ENW-89823A4KF Panasonic module unable to set HCI Baudrate higher than 115200

Tool/software:

Hi,

We are currently using this Panasonic module which is based on the CC2564 chip.

Using external STM32 as host MCU and Bluetopia bluetooth stack, we are unable to set the baudrate higher than 115200.

with baudrate of 115200, the pair and communication works flawlessly.

but once we set the baudrate to 1M, the pairing can still be done, but none of the communication goes through.

/* Configure uart parameter */

  HCI_DRIVER_SET_COMM_INFORMATION(&HCI_DriverInformation, 1, VENDOR_BAUD_RATE, cpHCILL_RTS_CTS);

  HCI_DriverInformation.DriverInformation.COMMDriverInformation.InitializationDelay = 100;



here return after mcu send hci command 


here mcu change baud rate after mcu receive respond from bluetooth module 

Also checked on the hardware side, there shouldn't be anything limiting the switching speed.

Kindly Help!

Thanks in advance.
