WL1271 Bluetooth can't piscan

Sajja,

From the logs shown above, it seems that you are using a custom OMAP 3730 board with the WL1271 and the uart interface for the BT is UART1. When the hciattach command was executed, the BTS firmware script  was downloaded to the chip and the device setup completed successfully. It means the uart interface functions properly.  The error "Can't set scan mode on hci0: Connection timed out (110)can" indicates that the chip is no longer responding to the host omap.

Is the WL1271 module from LSR / Murata /Jorjin? The bts file included in the TI SDK is for LSR module. There could be slight difference in BTS file from other vendors. Could you please verify whether the correct firmware bts script is being used in your system?   Do you have similar results when the WLAN is up or down?

Regards

Sinoj

Dear Sinoj,

Thank you very much,

1. Custom OMAP3730, and I'm connect BT with UART1,
2. WL1271 module from Jorjin,

My WLAN WLAN1271 are working well, didn't have any problem yet ( SDIO driver  +  "firmware.bin" 

in TI SDK (http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/4_01_00_09/index_FDS.html at WLAN/Bluetooth applications and drivers)

Could you please help me to locate the bts sctipt from Jorjin ? or Could you share the BTS firmware that running at lower speed like 2M or 115200 ?

Thank you in advance.

Sajja,

Please go to  below post to download 115K bts file; 

http://e2e.ti.com/support/low_power_rf/f/307/t/135887.aspx#518847

However, i don't think the problem is due to higher baud rate. To obtain right bts firmware for Jorjin module, you may need to contact Jorjin support team. Please refer to the below thread also;

Dear Sinoj,

Thank you for you reply, after I testing with both firmware BTS 2.25M, 115k  the result are same (error)

Error after command piscan.

#hciconfig hci0 piscan
Can't set scan mode on hci0: Connection timed out (110)


So I'm already request firmware BTS to Jorjin support team (if have) 


But I think firmware are load to TI WL1271 core , and Various Module should difference on RF part only , but 
core and communication should be same. then I should communicate with WL1271 after initialize TI core

BTW, Any suggestion to us , please help.

Sajja,

Thanks for the update.

There may be some clock and sleep mode configurations specific to Jorjin module in the bts file.   Please let us know the results once you try new bts file from Jorjin.

Regards

Sinoj

Sajja,

     Could you share with us the BTS file you are using please?

Dear Miguel,


I still waiting Jorjin to sent BTS file to us, It' seem too slow response.

But All 3 BTS files I using from TI , ( still not working with Jorjin module)

1.From SDK

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/4_01_00_09/index_FDS.html

Section TMS320DM3730 DVSDK

2. From Sinoj Advise
BTS file for 2.25Mhz clock (see below) please modify the name to TIInit_7.2.31.bts

3. Form Sinoj Advise
115200 the BTS file is: (see below) and modify its name to be TIInit_7.2.31.bts

Have a nice day.

Sajja A,

Nice to see your message.

Hopefully, BT will work with a proper BTS script file.

Sinoj

Sajja,

     Please try attached SP. Let us know which one works for you.

Dear Sinoj,

I just have firmware from Jorjin I have test but IT's need to enable wifi before using Bluetooth,
Thank you for your support.

Sajja A.

Dear Sinoj.

I just have firmware from Jorjin I have test but same as IT's firmware that  need to enable wifi before using Bluetooth,


Dear Miguel

After I test your zip file 5635.BT_5F00_firmware.zip have summary/Result are below,

1.bluetooth_init_wl1271_ 2.31_noSleep.bts from your zip file

this firmware (1)  can use bluetooth alone without enable wifi.

2.bluetooth_init_wl1271_ 2.31_xtal.bts
3.From SDK  http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/4_01_00_09/index_FDS.html
4.BTS file for 2.25Mhz
5.BTS file for 115200
6. Jorjin bts for 3Mhz

Those firmware (2-6) can't using bluetooh alone, need to enable wifi before use BT.

Could I know which one are most stable firmware ? or TI recommend ?

Thank you in advance.

Sajja,

Do you know if the module you are using has a XTAL for the fast clock source?

Regards,

Miguel

Dear Miguel ,

Fast Clock source are 38.4MHz 

Best Regards,
Sajja A.  

Sajja,

But is it an oscillator or a crystal? What is the module part number?

Rgds,

Miguel
