    Pairing issue with Bluetooth in CYW43455

    SaKr_4783036

      Hi Team,

       

      I am trying to bring up Bluetooth in UART using CYW43455 module.

      I have done the following steps:

       

      1. Enabled BT_REG_ON to output high.

      2. Bluez has been set up in the board.

      3. Copied the firmware from cyw-bt-patch/BCM4345C0_003.001.025.0144.0266.1MW.hcd at master · murata-wireless/cyw-bt-patch · GitHub  to /etc/firmware folder.

      4. I did hciattach and following are the logs.

      $ sudo hciattach -t 30 /dev/ttyTHS1 bcm43xx 3000000 flow

      bcm43xx_init

      Set Controller UART speed to 3000000 bit/s

      Flash firmware /etc/firmware/BCM4345C0_003.001.025.0144.0266.1MW.hcd

      Set Controller UART speed to 3000000 bit/s

      Device setup complete

       

      5. Then I tried pairing with bluetoothctl and got the following logs:

       

      $ sudo bluetoothctl

      [NEW] Controller 48:EB:62:C2:B8:C7 BlueZ 5.48 [default]

      Failed to pair: org.bluez.Error.AuthenticationFailed

      [CHG] Device 0D:61:95:00:1C:9B Connected: no

       

      I am getting the above issue " Failed to pair: org.bluez.Error.AuthenticationFailed ". Can you help me resolving this issue?

       

      Thanks,

      Sakthi
