  • Is it needed to "Disable flow control" while btattach-ing (bluez) a UART BT device to a Linux Host?
  • If yes, why?

This is specified in this tutorial, how to use the dongle:

Hi AnHu_4662101 ,

CYBT-413034-02 needs flow control to be enabled for HCI communication. Not sure regarding the test results of blog mentioned.

Did you try hciattach  with flow control enabled and see if it works ?

Hi AnjanaM_61​,

I've tested both:

  1. Flow control enabled (default)
  2. No flow control

`hciattach` is deprecated so I used `btattach` instead.  Both cases work.

To confirm, I understand now, recommended way is to "use" the flow control ?

Thanks.
