CC2564: CC2564B SIG test mode will go into low power mode

LEON YAN

Part Number: CC2564

Hi e2e,

Our customer is doing CC2564B certification, they need run cc2564B in SIG test mode, according our wiki, we help customer successfully run into SIG test mode, but found CC2564B will go into low power mode frequently.

Later we modified the bts file to disable low power mode as below, it works and not so frequently in low power mode, but found a new issue, CC2564B still goes into low power mode while we change the channel after 12 times.

we want to know that is it related to TI CC2564B itself? what's the root cause?

thanks in advance.

    Lei Yan,

    From the screenshot attached above, it looks like both Deep sleep and Big sleep are being enabled during your test mode.

    I would recommend skipping the last two commands altogether for RF/SIG test purposes.

    i.e. ...

    #################################################################
## START of CC2564 Adds-On
#################################################################

## Enable fast clock XTAL support
Send_HCI_VS_Fast_Clock_Configuration_btip 0xFD1C, 0x01, 0x00001388, 0x000007d0, 0xff, 0xff, 0x04, 0xff, 0xff, 0xff, 0xfa, 0x00, 0x00, 0x0000
Wait_HCI_Command_Complete_VS_Fast_Clock_Configuration_btip_Event 5000, Any, 0xfd1c, 0x00

## Enable eHCILL
#Send_HCI_VS_hcill_parameters 0xFD2B, 0x0010, 0x0050, 0x96
#Wait_HCI_Command_Complete_VS_hcill_parameters_Event 5000, Any, 0xfd2b, 0x00

#Send_HCI_VS_Sleep_Mode_Configurations 0xFD0C, 0x01, 0x01, 0x00, 0xff, 0xff, 0xff, 0xff, 0x0064
#Wait_HCI_Command_Complete_VS_Sleep_Mode_Configurations_Event 5000, Any, 0xfd0c, 0x00

#################################################################
## END of CC2564 Adds-On

    Hello ViHang,

    Thanks for your suggestion, and our customer replied that it keeps CC2564B active for 10 minutes and goes into low power mode again, do you know what's the reason, it's related to our ROM code or bts?

    and they also have a request of removing AVRCP/PAN profile in SDP, is it related to bts file? how we can remove it?

    BTW, they are using Bluez in Linux platform.

    thanks for your help.

    Most likely, neither. If running the RF tests through a stack like the BlueZ, the customer needs to take special care that any other stack activity like page/inquiry scans and Inquiry response do not interfere and terminate the test mode. If the issue persists, please share the FW logs.

    This is entirely related to the stack. Please find BlueZ stack related support on the open source linux forums.
