Hi,

We are using BCM943341WCD1_3 board for BLE verification.

But we are facing problem in detection of USB-UART port in ubuntu linux kernel v3.16.0.23.

The command #cat /proc/tty/driver/usbserial do not return the device minor version.

We feel the usb serial driver  (ftdi_sio.c) from (linux kernel v3.16.0.23) is not supporting the chip [FT2232HQ]. It support FT2232H.

Could you please let us know what is the issue.

If it is driver issue could you please share the FTDI driver.


Thanks, Srinivas

According the FTDI data sheet the FT2232HQ is only package different with FT2232H !

So you could follow the thread Troubles with Serial Terminal with x64 Ubuntu 12.04? to figure it our !

HI Jone,

Thank you for your reply.

As per the link "modprobe" did not resolve the issue.

But by putting entry into the device table we could see two ttyUSB0/1 device.

Could you please tel which UART port (ttyUSB0 or ttyUSB1) to use for Bluetooth interface?

is there any setting on the BCM943341WCD1_3  EVB board to configure bluetooth UART interface?


Thanks & regards, Srinivas

I think those two UART port not connect to BT!

You could check the EVB schematic, I believe which is already location in

SDK too!

There are one MCU include in EVB to control the WIFi/BT .

There are 'Quick startup Guide" , you should read first to know those two

ttyUSB port used for ?!

Best Regards,

Jone

Hi Jone,

Thank you for your reply.

Yes, I have read the "WICED-QSG202-R.pdf" and "WICED-EUM201-R.pdf".

In the "Quick startup guide" it is mentioned that "The WICED evaluation board has two logical USB devices: a USB-JTAG device and a USB-UART device."

So i understand that these two devices are ttyUSB0 and ttyUSB1. But which one belongs to whom is not mentioned.  My understanding is,

ttyUSB0 -->USB-JTAG device.

ttyUSB1 -->USB-UART device.

Is above understanding correct?

Is it possible to program the MCU to provide ttyUSB1 as Bluetooth-LE UART interface?

Thanks, Srinivas

I don't think you could do that!
