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.
Hi Karthikeyan
what bsp used in the case, atheros modules are not supported in latest nxp bsps.
One can try older releases which supported it, like L3.14.38 described on
Best regards
