Wl1835 chipset/interface misbehavior

Hello Wayen Zhang,

can you please add some more details?

Is everything works as expected when receiving a smaller file?
Does the system crash? or the chip is still functional?

Can you please add FW logs, sniffer logs and driver logs.

BR,
Chen Loewy

hi chen：
smaller than 6M is ok.

Is the uart problem？

If the baud rate is set to 115200, receive more than 6M of the file is ok .

Hello Wayen Zhang,

Without FW logs it's hard for me to find the root cause.

Most likely you are correct and it's a baud rate issue.
can you please try 921600 and let me know if that works?

HI chen:

could U tell me how to print FW log?

921600 also failed····：（

Hello Wayen Zhang,

You will need to do the following:

1. Dependent on the board you are using. Look at the schematics, Connect the BT_DEBUG pin GPIO.

2. Download the logger tool -
you can download all tools from the following link: www.ti.com/.../WILINK-BT_WIFI-WIRELESS_TOOLS

3. Configure the logger using the correct .xml and .ili files (should be part of the package of the .bts file you use for BT).

4. Once everything is setup correctly the logs will start showing up on the logger tool.

Thanks,
Chen Loewy

HI chen:

bt log:

6648.Untitled.rar

Hello Wayen,

I went over the log file.

What i can see is the following:

1. For some reason you download the initscript twice (no idea why do you do that) so please make sure you only download the initscript once.

2. We start receiving a file - and after the first few packets we stop receiving any data. 

3. The only suspect i have which i can see in the log file is the AFH - (automatic frequency hopping).

Please try adding the following commands to the end of your init script.

# Disable AFH Master

Send_HCI_VS_Set_Supported_Features 0xFF26, 0x05, 0x03, 0x00

Wait_HCI_Command_Complete_VS_Set_Supported_Features_Event 5000, 0x00, 0xff26, 0x00

 

# Disable AFH Classification Master

Send_HCI_VS_Set_Supported_Features 0xFF26, 0x05, 0x04, 0x00

Wait_HCI_Command_Complete_VS_Set_Supported_Features_Event 5000, 0x00, 0xff26, 0x00

 

#Command to disable AFH channel assessment :

Send_HCI_Write_AFH_Channel_Assessment_Mode 0x00

Wait_HCI_Command_Complete_Write_AFH_Channel_Assessment_Mode_Event 5000, 0x00, 0x0c49, 0x00

 

# Disable AFH Slave

Send_HCI_VS_Set_Supported_Features 0xFF26, 0x04, 0x03, 0x00

Wait_HCI_Command_Complete_VS_Set_Supported_Features_Event 5000, 0x00, 0xff26, 0x00

 

# Disable AFH Classification Slave

Send_HCI_VS_Set_Supported_Features 0xFF26, 0x04, 0x04, 0x00

Wait_HCI_Command_Complete_VS_Set_Supported_Features_Event 5000, 0x00, 0xff26, 0x00

 

please try.

Thanks,
