Linux/CC2564C: CC2564C:Can not disable BLE function

Part Number: CC2564C

Tool/software: Linux

Hi,

HCI_VS_LE_Enable (0xFD5B) 0x01 0x01 command can enable low energy function which could be observed by application tool by detecting beacon data.

HCI_VS_LE_Enable (0xFD5B) 0x00 0x00 command seems failed since that application tool still can detecting the changing beacon data.

To disable BLE function, does anything else need to do?

    HCI_VS_LE_Enable (0xFD5B) 0x00 0x00 should disable the BLE.

    Please share the CC2564C FW logs of this scenario.

    Peijie,

    From the logs, I see that you are using the CC2564B and not the CC2564C. Both devices handled the HCI_VS_LE_Enable function in the exact same way, but I wanted to state that for the record since the subject line mentions CC2564C.

    The BLE_DisableNOK.lgr logs show that the HCI_VS_LE_Enable 0xFD5B 0x00 0x00 command was sent from the host (#1277) while the LE Advertise is still active (#1240 HCI_LE_Write_Advertise_Enable 0x01). Because of this, the CC2564B returns the 0x0C (Command Disallowed) error code in the command complete event (#1278) of the HCI_VS_LE_Enable command.

    All LE procedures (i.e. advertising, scanning, active LE connections or LE test modes) must be stopped before the HCI_VS_LE_Enable 0xFD5B 0x00 0x00 command can succeed in disabling the LE.

    Best regards,

    Vihang

    Dear Vihang,

    HCI_VS_LE_Enable 0xFD5B 0x00 0x00 works, thanks for your information.

    And I found another issue that after disable LE function successfully even though, the WBS of headset won't output voice.

    Do you have any ideas?

    Thanks.

    Hi Peijie,

    Before using the WBS, or any assisted modes, the AVPR add-on must be downloaded to the device. As you can see in the datasheet, you can either run BLE or assisted mode (WBS or A3DP) at a time. The BLE mode is activated by downloading the BLE add-on (found in the service-pack release) to the device and assisted mode is activated by downloading the AVPR add-on to the device.
    The appropriate add-on must be downloaded each time when switching between BLE and assisted modes.

    Best regards,
    Vihang
