Bluetooth scanning is not working in WL1271

Other Parts Discussed in Thread: WL1271

Hi,

      We are using WL1271 chip in ARM core with linux 2.6.28.2 kernel version(Bluez version is 4.40 ). BT firmware version is v2.0.31. Baudrate selected in bts file(TIInit_7.2.31.bts) is 115200 and flow control is also disabled. We have executed following steps to bringup the BT interface

1. dbus-daemon --system

2. start bluetoothd

3. hciattach -t 60 ttyS0 texas 115200 noflow

4. hciconfig hci0 up

5.hcitool scan

We could see that  BT interface(hci0) is up and running after step 4, but during scan it is not showing any BT device in the list.

Is there any other setings/configurations missing from the above step. Any help would be appreciated.

 

Thanks & Regards

Dhanesh

    Hi Dhanesh,

    Could you please run the following command after step 4 and verify whether other BT devices can detect WL1271.

    # hciconfig hci0 piscan

    Why is flow control disabled?

    Also, try to do sdp browse any known devices with the following command.

    # sdptool browse <BD_ADDR>

    Thanks,
