Information for building TI Bluetooth Stack for WL1831 on ti sdk 8 & ti sdk 1

Srini

Other Parts Discussed in Thread: WL1831, WL1831MOD

Dear Ti e2E Community,

As am new to Bluetopia and using w1831, For SDK 8. am following the below link for bulding buletooth stack, But am stuck up with few steps as described below

http://processors.wiki.ti.com/index.php/TI_Bluetooth_Stack_for_WL18xx_-_Getting_Started_Guide.

1. Could you please let me know the kernel menuconfigurations & the required services with detailed steps to be run in the rootfs for for w1831 BT module in
ti sdk 8

2. I have downloaded the AM335xBluetopiaLinuxProduction-4.0.1.4.2U-linux-x64-installer.run (as my ubuntu host machine is 64 bit) & I have installed, & it is listing the following items

srinivasan@tata-HP-Elite-7100-Microtower-PC:~/Platform/BT$ ls
AM335xBluetopiaLinuxProduction-4.0.1.4.2U-linux-x64-installer.run ReleaseNotes.pdf
BluetopiaPM SRAS_1084-298648-v1-WL8_Bluetooth_SLA.pdf
Documentation uninstall
install.sh uninstall.dat
PICSSupportedFeatures.pdf Uninstall WL18xx+AM335x Bluetoouth Source and Object Code - Production.desktop
README.pdf
srinivasan@tata-HP-Elite-7100-Microtower-PC:~/Platform/BT$

3. And I have copied the firmware file (TIInit_11.8.32.bts) /lib/firmware of my Rootfs

4. But I need to build, the bluetooth stack

But I am unable to find the build folder, setup-bt.sample file, & source configure.sh inside the installation folder as shown in the above listing

4. Could you please let me know, can this hcitools can be used for verifiying the bluetooth operations like as shown below, could you please help me in providing the link with detaled steps for cross_Compiling & installing hci tools in ti sdk 8??

hciconfig -a

> hciconfig hci0 up

> hcitool scan

5. If hcitools cannot be used in ti sdk 8, could you please let me know how the above operations can be performed using ti custom bluetopia applications ie., interface lisitng, & making the interface to be up scanning & file transfer

6. For time being inorder to validate bluetooth on hardware, I builded SDK 1 (ti-processor-sdk-linux-am335x-evm-01.00.00.03 kernel & used ./build_wl18xx.sh) by downloading from ti website & used arago-base-tisdk-image-am335x-evm_SDK1 rootfs & am seeing the following errors as shown in the logs & dts as attached above

Could you please let me know why am seeing the above errors, as am I doing anything wrong??

Kindly do the needful as early as possible, am trying to build the Bt stack, but am unabel to build it from yesterday

Many Thanks in advance

Hi,

The best place to start is from: processors.wiki.ti.com/.../WiLink8_Linux_Getting_Started_Guide
The stack binaries are only provided along with sample apps. This can be copied to the target. Please see the above page.

"hcitool" is available. The TI Bluetooth Stack also provides "SS1Tool" which gives similar functionality as hcitool.

Regards,
Gigi Joseph.

Dear Gigi,

Thanks a lot for your quick responses & would really appreciate the same

In the above attached logs, could you please let me know why am I seeing the below highlighted error messages,

And am using USB1-UART3 as Tx- RX (USB-DP & USB-DM) lines.

Since we are not using CTS/RTS we have set flow_cntrl to <0> in kim & Comment out line 208 in src/uim/uim.c (ti.c_cflag |= CRTSCTS) & baud rate is set to 115200

HI,

Can you tell me what changes you've done to the uim code and for what reason?
I don't recollect seeing the below log before.

"COMMENTED OUT ti.c_cflag |= CRTSCTs"

The error suggests that the uim is not able to get a response from the device. This could mean many things - that you've the wrong dts mapping for BT_EN, or you got the uart device name wrong, or there is a uart issue on the platform.

First thing to verify would be to check proper device power up (as per datasheet). Then to rule out any uart issue on the platform.

Please also tell me what changes you have made to the original code?

Regards,
Gigi Joseph.

Sorry Gigi,

1. "COMMENTED OUT ti.c_cflag |= CRTSCTs" that is the print added by me in ~/wl8-build/build-utilites/src/uim/uim.c & commented out the line as shown below

static int set_baud_rate(int dev_fd)

{

UIM_START_FUNC();

struct termios ti;

tcflush(dev_fd, TCIOFLUSH);

/* Get the attributes of UART */

if (tcgetattr(dev_fd, &ti) < 0) {

UIM_ERR(" Can't get port settings");

return -1;

}

/* Change the UART attributes before

* setting the default baud rate*/

cfmakeraw(&ti);

ti.c_cflag |= 1;

printf("COMMENTED OUT ti.c_cflag |= CRTSCTs\n");

// ti.c_cflag |= CRTSCTS;

/* Set the attributes of UART after making

* the above changes

tcsetattr(dev_fd, TCSANOW, &ti);

/* Set the actual default baud rate */

cfsetospeed(&ti, B115200);

cfsetispeed(&ti, B115200);

tcsetattr(dev_fd, TCSANOW, &ti);

tcflush(dev_fd, TCIOFLUSH);

UIM_DBG("set_baud_rate() done");

return 0;

}

Hi,

Why did you comment "ti.c_cflag |= CRTSCTS;" ?
This is mandatory.

Gigi Joseph.

Hi,

In my design, am not using CTS & RTS Signals in the hardware & am using USB1_DP & USB1_DM as UART3 RX & TX signals so I commented "ti.c_cflag |= CRTSCTS;" , but having this uncommented

The below are the log messages seen..

Hi,

Please check the hardware integration guide - www.ti.com/.../swru437
The RTS/CTS lines are mandatory.

Hi Gigi,

Just one doubt w.r.t BT_EN pin, Could you please let me know does the BT_EN pin needs to be continously held high, duirng bootup for getting the chip to be proper BT functioning

or Is that enough that BT_EN pin goes high only during if "hciconfig hci0 up" is activated??, as am currently seeing that BT_EN pin goes high only if "hciconfig hci0 up" is activated. is this is expected behaviour???

Kindly do the needful as early as possible,

Many Thanks in adavnce

Yes, it is the expected behaviour.

Thanks a lot for your quick responses Gigi,

Could you please jus reconfirm w.r.t WL_EN pin as well ? is that needs to be continously held high, duirng bootup for getting the chip to be proper WLAN functioning??

or Is that enough that WLAN_EN pin goes high only during if "ifconfig wlan0 up" is activated??, as am currently seeing that WLAN_EN pin goes high only if "ifconfig wlan0 up" is activated. is this is expected behaviour???

Kindly do the needful as early as possible,
Many Thanks in adavnce

Dear Gigi,

As of now my BT is up, but few devices are not getting scanned sometimes, could you please let me know is there any limitations on wl1831 module for getting scanned only few devices if you see in the below logs for ex:Micromax A110 is not getting scanned sometimes or am I missing any sequence??

I have attached DTS for your reference

Hi,

Please verify that the latest bts file is being used. The bts file is available at: www.ti.com/.../wl18xx-bt-sp
There are no limitations on the wl1831mod to not scan certain devices as long as they are discoverable and within range.

Please also note that it's not guaranteed that all discoverable devices are discovered every time during a scan process. Please see: "Inquiry Substate" in the BT spec for more details.

Regards,
Gigi Joseph.

Could you please let me know why am seeing the above errors, as am I doing anything wrong??
