Linux/CC2564MODA: CC2564MODA with 3 Mbps Baud rate issues

Tool/software: Linux

Hello,

Is it possible for CC2564MODA to communicate at 3mbps baud rate.

Currently its working fine with 115200 baud rate. 

But as i need higher speed, i modified the  module baudrate to 3mbps as below.

cmd.uart_prefix = HCI_COMMAND_PKT;
cmd.hci_hdr.opcode = HCI_HDR_OPCODE;
cmd.hci_hdr.plen = sizeof(unsigned long);
cmd.speed = cust_baud_rate;  // setting 3mbps here

But its still remains with 115200 baudrate.

Thanks
