WILC3000 Bluetooth Issue

Hi Team,
I am using WILC3000 WiFi/Bluetooth chip in my custom board.
I am using iMX6 processor with linux version 4.1.15.
I have downloaded the latest version of the wilc3000 driver from the microchip site and able to port it to my Linux kernel successfully.
I have tested the WiFi features and it is working fine.
When I started testing the bluetooth I  am facing issues.
I have given below commands :
[<font]echo BT_POWER_UP > /dev/wilc_bt
[<font]echo BT_FW_CHIP_WAKEUP > /dev/wilc_bt
[<font]echo BT_DOWNLOAD_FW > /dev/wilc_bt
[<font]echo BT_FW_CHIP_ALLOW_SLEEP > /dev/wilc_bt
[<font]hciattach ttymxc0 any 115200 noflow 
[<font]hciconfig -a
[<font]hciconfig hci0 up
[<font]ln -svf /usr/libexec/bluetooth/bluetoothd /usr/sbin
[<font]bluetoothd -n &
[<font]hciconfig hci0 leadv
 
[<font]bluetoothctl for scan and connect.
Below is the output of these commands:
echo BT_POWER_UP > /dev/wilc_bt
at_pwr_dev: open()

But it is not showing any near by device.
 
 
[<font]I tried to use hcitool to scan and connect and below is the log for hcitool

When I gave hciconfig hci0 -a I am getting input/output error like below:
