I m using Atheros AR6233 chip and YOCTO platform. I have enabled the WiFi.
Facing difficulty in enabling Bluetooth.
I cannot detect the hci0 interface. This module is basically UART interface.
I m using Bluez5.41 version.
My Kernel configuration :
+#BlueTooth config#
+CONFIG_BT=y
+CONFIG_BT_RFCOMM=y
+CONFIG_BT_RFCOMM_TTY=y
+CONFIG_BT_BNEP=y
+CONFIG_BT_BNEP_MC_FILTER=y
+CONFIG_BT_BNEP_PROTO_FILTER=y
+CONFIG_BT_HIDP=y
+CONFIG_BT_HCIUART=y
+CONFIG_BT_HCIUART_ATH3K=y
+CONFIG_BT_HCIUART_3WIRE=y
I have added the Bluez packages as follows:
BLUETOOTH_STACK = "\
bluez5 \
bluez5-obex \
bluez5-noinst-tools \
bluez5-testtools \
uim \
bt-enable \
"

Initialization timed out.
What am i missing ? Any Firmware need to be loaded for this module ?
Please provide the guidance.
Thanks in advance.
