iMX6/SABRE-AI base board bluetooth issue

taylerko — Thu, 02 Oct 2014 01:45:17 GMT

I would like to develop Bluetooth software on iMX6, my device is iMX6QAICPU board and SABRE-AI base board.

I already connected CSR 8311 BT chip to BT Module Connector (J32) of SABRE-AI base board.

As I can see from system there is 3 UART port:

ttymxc1, ttymxc2 and ttymxc3 (debug port)

We test ttymxc1 and ttymxc2 but both are fail to read/write.

Which UART device should be used for this BT module connector (J32) ? or should I modify anything from BSP first?

Thank you for help...

Hi Tailer

it is ttymxc2 (UART3) you can check i.MX6_SABRE_AI_DESIGNFILES : Design files

p.20 SCH-27142

also please check below for supported BT chips

i.MX_6Dual6Quad_Linux_Reference_Manual.pdf

Chapter 41Bluetooth Driver L3.0.35_4.1.0_LINUX_DOCS

Freescale BSP does not support/provide CSR BT driver one

needs to apply for help to vendor of these chip.

Best regards

igor
