WL1835MOD: BT HCI UART: List of available baud rates

Hello Markus,

To change the baudrate from its default of 115200 the following HCI command can be used

The maximum baud rate is 4Mbps.

Im not sure what you mean by the HCI-test-arm source code however we do have this RF testing guide that could be helpful?

Kind regards,

Sorry but you are not answering the question

I know what the default baud rate is, what the maximum is and what command to change it on the controller is

The question is exactly which baud rates it supports, since that is missing in the manual/docs, and it seems I can change the baud rate below 115200, but I can't get it higher

I thought the hci-test-arm was some TI-made tool, I might be wrong, but it was posted here

Hi markus,

Try these baud rates;

Im not sure about HCI-test-arm, however, we do have the HCI tester tool which is part of the WIlink wireless tools

Where does that code come from?

I don't think that is an complete list as 3000000 is missing from there which I've seen many people have successfully used

Is there a list of what baud rates the module supports or not?...

Is it hard to understand my question or what is happening? I want a list of supported baud rates for the module since that is very unclear from the datasheet

Now you have made 2 answers that didn't answer my question at all and I wonder why.

If there isn't a list just say so..

But then can you explain what clock it runs with and how the clock divider work? Then I can figure out what matching baud rate it can take.

My base baud is 1536000, that means I can't go higher than that, I'm trying to find a common baud rate between my host and the module.

Hi Markus,

There is not a list of supported baud rates that I know of. The rates I provided above are the set rates from the SPP demo. Ill get back to you next week, on what clock the UART works with.

Thank you, that would be very helpful
