CC2564: Connecting with a STMF4

okay i got the problem.

It appears when the baud rate changes. but device want to change the baud rate to "3" .

is there anywhere a description what this 3 means?

Tobias,

If your question is how this driver is written, then you should reach out to ST support for help.

There is a function "SetBaudRate" and there is a switch case:

case 3:
{
BaudRate = 921600;
break;
}

I am also working with cc2564 and having problem to go higher with the baudrate than 1,000,000. Above that the BT stack isnt correctly initialized. 

Manuska,

Can you look at the UART on a oscilloscope, and ensure the UART is following the TIming requirements in the datasheet? (5.7.3.1)

Hi Tobias,

which baudrate you are using now?

With best regards from Ludwigsburg :)
