How to configure WL1831 Bluetooth device with hci commands to scan the other WL1831 Bluetooth device

Other Parts Discussed in Thread: WL1831

I want to use one WL1831 BT device  to scan the other WL1831 BT device.

The hci0 device can be enabled by typing "hciconfig hci0 up" but there is nothing found after typing "hcitool scan" command.

I turned on BT function of android phone, and run it again. The BT device of android phone can be found. 

Could anyone provide some suggestions? How can I configure the other  WL1831 Bluetooth device to make it discovered.

Thanks.

Brian

    Hi Brian,

    It depends on the BT Stack that you're using.
    With the BlueZ stack (which I believe is what you're using), you can type "hciconfig hci0 piscan" to enable page & inquiry scans.

    You can also check on some external BlueZ forums for a better response.

    Hi Joseph,

    Thanks for your reply.
    I use ti-processor-sdk-linux-am335x-evm-01.00.00.03-Linux-x86-Install.bin SDK to run the test.
    I type the "hciconfig hci0 piscan" command but it still not work for me.

    You may refer to my hci0 information list.

    # hciconfig hci0 -a

    Hi Brian,

    Can you confirm if the firmware has been successfully downloaded?
    Please use the latest BTS from: www.ti.com/.../wl18xx-bt-sp

    Hi Joseph,

    It should be my test environment issue.
    After changed a RF antenna, "hcitool scan" can show the other WL1831 BT device.
    Thanks for your help.

    Brian
