UART2 communication port No to communicate using hci_uart and bluetopia stack for tiwi-ble

Hi ,

I am trying to test the coonectivity of the bluetooth in tiwi-ble using bluetopia in Nitrogen6x board.

We want to test the connectivity of tiwi-ble using hci-uart communication.

The command line option is given below.

I am trying run ./LinuxHCI 1 <com port no> <baud rate>

here '1' is for UART, '0' is for USB and '2' is for BCSP.

I wanted to know what is the communication  port no(ttymxc2) that needs to passed above . The baud rate used is 3mbps. 

Regards,

Ashwath

    Hi,

    I think it is UART3. But to make sure please check your board file.

    Have you checked the Readme file from Bluetopia stacks. As far as I know the Bluetopia stack provided by TI is ment for AM335x platforms.

    If you want a bluetopia stack for the different platform you need to contact StoneStreet One at sales@stonestreetone.com.

    Hi Sundeep,

    Yes, it is using UART3.

    I am getting following error message when I to try to communicate with the chip using hci_uart. I need to pass appropriate command line arguments.

    root@freescale /home$ ./LinuxHCI 1 3 3000000
    Stack Initialization on Port 3 3000000 (UART) Failed: -14.
    Unable to open the stack.
    I am no sure  why I am getting this error message. May the third parameter '3' is causing the issue. This is where I am stuck. I am sure that baud rate is 3mbps. 

    How to get exact communication port number for UART3.

    Regards,

    Ashwath

    Hi,

    I have got the update for the issue.

    The error code 14 indicates that  BTPS_ERROR_HCI_DRIVER_ERROR as given in bluetopia. It says this error comes due to uart- communication. In our case it is UART-3. The error returned is from  bsc_initialize function in LinuxHCI.c

    How can resolve this error.

    Can any body give some pointers to solve the issue.

    Best Regards,

    Ashwath

    Hi,

    As mentioned earlier see the Readme file from Bluetopia stacks. As far as I know the Bluetopia stack provided by TI is ment for AM335x platforms.

    If you want a bluetopia stack for the different platform you need to contact StoneStreet One at sales@stonestreetone.com. as the library might not be compatible.

    Hi,

    I am testing file transfer from Bluetooth.

    BT is pairing with my handset ok.but when file transfer it's gives me connection error on handset.

    and also i was run LinuxFTPM_CLT application for file transfer.

    FTPM>Connect 103B5910218A 1 0
    Remote Device Properties Changed.
    BD_ADDR:       103B5910218A
    Device Flags:  0x800005CD
    Connect State: TRUE
    FTPM>
    etFTPMConnectConfirmation, FTPConnectionID: 0x0001, Status 0x0002
    BD_ADDR: 103B5910218A

    FTPM>dir
    You must open an FTP Client before issuing this command.
    Function Error.


    How to open FTP Client ? Any idea ?

    Thanks

    Hi Tejas,

    etFTPMConnectConfirmation, FTPConnectionID: 0x0001, Status 0x0002

    Status = 0x0002 => "Connection Refused"

    The FTP Server (remote) is refusing the connection.

    Regards,
    Gigi Joseph.

    Client>
    etFTP_Client_Connect_Confirmation, FTPID: 0x0012, Status 0x0002
    BD_ADDR: 103B5910218A

    Status goes to 0x0002 "Connection Refused"

    Hi Tejas,

    Like I said, the remote device is refusing the connection. Please check the remote device and confirm (1) if it has FTP Server running and (2) a pending authentication/service access request which was not accepted.

    Gigi Joseph.
