wl1835mod bluetooth driver kernel 3.2

Hi Patrick,
Have you included the appropriate CONFIGs?

#enable bluetooth support
CONFIG_BT=y
CONFIG_TI_ST=y
CONFIG_BT_HCIUART=y
CONFIG_BT_HCIUART_LL=y
CONFIG_BT_WILINK=y

Iain

Hello Ian,

There are off, that is what is in the guide: CONFIG_BT=N. I will change that.

I have a look, but I cannot find the CONFIG_TI_ST or WILINK, how is that possible, also after I set the CONFIG_BT

Patrick

I took that example from a 3.10 build I had handy, so they may not be in 3.2. I'd diff with a TI SDK6.0 which is 3.2 based and supports wl18xx.
Iain

Hello Ian,

I did have a look at the sdk6.0, but when I run menuconfig, I see:

-Bluetooth subsystem support ---> Bluetooth device drivers ---> HCI Uart driver, but no wilink support, only:

UART (h4) protocol support

BCSP protocol support

ATheros AR300x serial support

HCILL protocol support.

Regards

Patrick

Hello Iain,

Thanks for the information, I did what you said and changes also my board file part like the one of am335x_evm:

/* Module pinmux for bluetooth on uart1 */
static struct pinmux_config uart1_wl18xx_pin_mux[] = {
{"uart1_ctsn.uart1_ctsn", OMAP_MUX_MODE0 | AM33XX_PIN_INPUT},
{"uart1_rtsn.uart1_rtsn", OMAP_MUX_MODE0 | AM33XX_PIN_OUTPUT},
{"uart1_rxd.uart1_rxd", OMAP_MUX_MODE0 | AM33XX_PIN_INPUT_PULLUP},
{"uart1_txd.uart1_txd", OMAP_MUX_MODE0 | AM33XX_PULL_ENBL},
{NULL, 0},
};

static struct pinmux_config wl18xx_pin_mux[] = {
{"mii1_rxd0.gpio2_21", OMAP_MUX_MODE7 | AM33XX_PIN_OUTPUT},
{"mii1_txd0.gpio0_28", OMAP_MUX_MODE7 | AM33XX_PIN_INPUT},
{"spi0_sclk.gpio0_2", OMAP_MUX_MODE7 | AM33XX_PIN_OUTPUT_PULLUP}, /*BT_EN */
{NULL, 0},
};

static void wl18xx_bluetooth_enable(void)
{
int status = gpio_request(am335xevm_wlan_data.bt_enable_gpio,
"bt_en\n");
if (status < 0)
pr_err("Failed to request gpio for bt_enable");

pr_info("Configure Bluetooth Enable pin...\n");
gpio_direction_output(am335xevm_wlan_data.bt_enable_gpio, 0);
}

/* wl18xx init */
static void wl18xx_init(void)
{
struct device *dev;
struct omap_mmc_platform_data *pdata;
int ret;

/* Register WLAN and BT enable pins based on the ispeak board(cip30x) */
am335xevm_wlan_data.wlan_enable_gpio = GPIO_TO_PIN(2, 21);
am335xevm_wlan_data.bt_enable_gpio = GPIO_TO_PIN(0, 2);

wl18xx_bluetooth_enable();

setup_pin_mux(wl18xx_pin_mux);

if (wl12xx_set_platform_data(&am335xevm_wlan_data))
pr_err("error setting wl12xx data\n");

dev = am335x_mmc[1].dev;
if (!dev) {
pr_err("wl12xx mmc device initialization failed\n");
goto out;
}

pdata = dev->platform_data;
if (!pdata) {
pr_err("Platfrom data of wl12xx device not set\n");
goto out;
}

ret = gpio_request_one(am335xevm_wlan_data.wlan_enable_gpio,
GPIOF_OUT_INIT_LOW, "wlan_en");
if (ret) {
pr_err("Error requesting wlan enable gpio: %d\n", ret);
goto out;
}

pdata->slots[0].set_power = wl18xx_set_power;
out:
return;
}

I followed the guide Smart_Home_and_Energy_Gateway_Software_Manual where at the chapter: Bluetooth

When I at Running Bluetooth section and follow these steps, I get the following:
./SS1BTPM &
./LinuxGATM_CLT
GATM>Initialize 1
BTPM_Initialize() Succes: 0
DEVM_RegisterEventCallback() Succes: 5
GATM>SetDevicePower 1
DEVM_PowerOnDevice() Failure: -14, Unkown Error.
Function Error.

What does this mean?

Hi Patrick,

DEVM_PowerOnDevice() Failure: -14, Unkown Error. basically means that the stack was unable to power on bluetooth device and download the firmware. It is the equivalent step to "hciattach ttyO4 texas 3000000" if you are familiar with Bluez.

Possible failure mechanisms are:
1. BT_EN is not being driven correctly. Check with a scope.
2. There is no or an incorrect firmware file in /lib/firmware. Download the current one (v3.6.1) from git.ti.com/.../TIInit_11.8.32.bts . This is documented at processors.wiki.ti.com/.../WL18xx_Bluetopia_Platform_Manager_Demo_Guide
3 there is no flow control on the UART. Should be able to identify if this is problem with a scope.

Iain

Hello Iain,

It was correctly that the BT_EN not was driven corretly, this comes because the module gpio_en.ko was not loaded correctly. I used the module from the SDK 6.0, but this has a kernel 3.2, while I have a kernel 3.2.21, so after recompiling with the correct link to my kernel, the module loads okay.

I did used the script what is avaliable in rootfs: BT_Init.sh, now I see a correct BT_EN response. The firmware I all ready have placed at /lib/firmware. How ever I get know the following error:

# BT_Init.sh
GPio valie is :2
WL1271: BT Enable
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/TIInit_11.8.32.bts
Loaded BTS script version 1
texas: changing baud rate to 3000000, flow control to 1
Can't set line discipline: Invalid argument
Can't initialize device: Invalid argumnt
#

What does this means? All look okay, but I get this errors.

Thanks for the help so far.

Regards
Patrick

Patrick,
I don't have a 6.0 build around to test with. I googled and found this www.linuxforums.org/.../183146-bluez-rn42-bluetooth-module-hciattach-fails.html.
It suggests a missing driver. Can you check your dmesg to see which drivers are getting loaded?
Iain

Hello,

I made some changes to the kernel and now I get new errors:
# BT_Init.sh
GPio valie is :2
WL1271: BT Enable
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/TIInit_11.8.32.bts
Loaded BTS script version 1
texas: changing baud rate to 3000000, flow control to 1
Can't set device: Protocol not supported
Can't initialize device: Protocol not supported
#

What protocol is meant here?

Regards
Patrick

Hi Patrick,
Looks like all the key drivers are there. This is now outside my expertise so I'll ask someone else to comment.

Hello,

Thanks for all the and information, it now works.
Also it did look like I missed some protocols. I rebuild the kernel again with:
L2CAP, SCO, RFCOMM, RFCOMM TTY, BNEP, HIDP protocols support.

Then I ran the BT_Init.sh script and the device setup is complete. I did a scan and did found some bluetooth devices.

Thanks & regards
Patrick

Hello,

After trying with some software like bt-device, I can pair with my phone. But looking at the Bluetopia stack, I thought I would that give a try, because this look at my a nicer stack.

But there is a problem, after a reboot of my device and I start :
./SS1BTPM &
./LinuxDEVM
DEVM>Initialize 1
BTPM_Initialize() Succes:0
DEVM_RegisterEventCallBack() Succes: 5
DEVM>SetDevicePower 1

DEVM_PowerOnDevice() Failure: -14, Unknow Error.
Function Error.
DEVM>

I followed the guide for the libBTPSVEND and rebuild SS1BTPM. In BTPSVEND.c I have the following(I leaved the comment):
static Boolean_t VendorCommandsIssued;

Boolean_t BTPSAPI HCI_VS_InitializeBeforeHCIOpen(HCI_DriverInformation_t *HCI_DriverInformation)
{
VendorCommandsIssued = FALSE;

HCI_DRIVER_SET_COMM_INFORMATION(HCI_DriverInformation, 0, 0, cpHCILL_RTS_CTS);

HCI_DriverInformation->DriverInformation.COMMDriverInformation.COMDeviceName = "/dev/ttyO1";

HCI_DriverInformation->DriverInformation.COMMDriverInformation.COMPortNumber = 1;

return(TRUE);
}

Boolean_t BTPSAPI HCI_VS_InitializeAfterHCIOpen(unsigned int HCIDriverID)
{
return(TRUE);
}

Boolean_t BTPSAPI HCI_VS_InitializeBeforeHCIReset(unsigned int HCIDriverID, unsigned int BluetoothStackID)
{
if(!VendorCommandsIssued)
{
VendorCommandsIssued = TRUE;
}

return(TRUE);
}

Boolean_t BTPSAPI HCI_VS_InitializeAfterHCIReset(unsigned int HCIDriverID, unsigned int BluetoothStackID)
{
return(TRUE);
}

Boolean_t BTPSAPI HCI_VS_InitializeBeforeHCIClose(unsigned int HCIDriverID, unsigned int BluetoothStackID)
{
return(TRUE);
}

Boolean_t BTPSAPI HCI_VS_InitializeAfterHCIClose(void)
{
return(TRUE);
}

Boolean_t BTPSAPI HCI_VS_EnableFeature(unsigned int BluetoothStackID, unsigned long Feature)
{
return(FALSE);
}

Boolean_t BTPSAPI HCI_VS_DisableFeature(unsigned int BluetoothStackID, unsigned long Feature)
{
return(FALSE);
}


What is wrong, because the bluez tools looks to work, but the bluetopia tools not

Thanks in advanced

Hi,

Is the gpio_en.ko module running, you should find at location /lib/modules/3.2.0/kernel/drivers/bt_enable/gpio_en.ko.

Make sure that "bt_enable_gpio" is configured correctly and build it under board-support/extra-drivers/bt-enable-1.0/ (in am335x case it is gpio_en_am335x.c) and place it at the above mentioned location and try.

Hello,

If it is correct the module is working, here is example when I use hcitools etc.

root@ispeak:~# insmod /lib/modules/3.2.21/kernel/drivers/bt_enable/gpio_en.ko

[ 48.374812] Gpio value is :2

So I know the module is function, but when I know run the Bluetopia stack 

root@ispeak:~/ss1# ./SS1BTPM &

root@ispeak:~/ss1# ./LinuxSPPM

.......

SPPM>Initialize 1

BTPM_Initialize() Success: 0.
DEVM_RegisterEventCallback() Success: 5.
SPPM>SetDevicePower 1

DEVM_PowerOnDevice() Failure: -14, Unknown Error.
Function Error.

Kind regards

Hi,

What is the Bluetopia SDK version you are using? where did you get the Bluetopia SDK for SDK 6?

Hello,

The version number is 4.0.1.4.2, I did downloaded the AM335xBluetopiaLinuxProduction-4.0.1.4.2U-Linux-installer.tar.gz from the website.

Is this not compatible with SDK 6.0? Or is het better to use the bluez stack?

Regards,
Patrick

Hi,

No, this version is not compatible with SDK 6.0. It works with SDK 7.0 (Shared transport (ST), No more GPIO)

Hello,

Okay thanks for you help.

Then I will goto the Bluez tools and look if I can setup and audio connection to my phone.

Kind regards

Patrick
