Hello All ,

 

I am using sabresd-6q freescale board .

I have integrated Broadcom Bluetooth chip over UART interface .

RX/TX lines are working , as its confirmed using loop-back test in HW . 

CTS/RTS lines are not working.

As bluetooth vendor firmware works with flow control , there is must for handshaking to happen between host and controller.

Can any one clarify , whether the UART protocol is tested on sabresd board .?

 

Is there any dependency in S/W , so as to enable / make CTS/RTC lines work?

 

I carried out serialAndroidTest , Basically testing the working of CTS/RTS lines on sabresd-6q board , the test is failing .

 

Can any one help , how to debug this RTS/CTS issue ?
