Re: [bluetooth-dev] Ericsson_Set_UART_Baud_Rate vs. Negotiation Protocol in HCI232
as I understood the Ericsson HW does not use the HCI over RS232 layer
OpenBT also does not support RS232 transport layer for HCI packets. The
differentiates between UART and RS232 transport. I didn't see any stack
using the second.

The Ericsson_Set_UART_Baud_Rate command is used to set the UART speed
for HCI communication to a different value than the default baudrate
(that is 57600 for Ericsson HW). This is vendor dependant (don't know

Ericsson HW does not implement the negotiation protocol (as far as I
know), since it does not use the RS232 transport layer.
Hope that helps.
