{{PageHeader|How to enable Murata Bluetooth on VisionSOM-6ULL}}
== Configuring device tree to enable UART5 interface for Murata Bluetooth ==
Murata 1DX requires UART interface with RTS and CTS lines and one GPIO reset line for Bluetooth part. On VisionSOM-6ULL you should apply this configuration in the device tree (details on modifying device tree are available in [[How to customize Debian 9.2 device tree|How to customize Debian 9.2 device tree]] article):
<pre>...
pinctrl_uart5: uart5grp {
fsl,pins = <
MX6UL_PAD_CSI_DATA00__UART5_DCE_TX 0x1b0b1
MX6UL_PAD_CSI_DATA01__UART5_DCE_RX 0x1b0b1
MX6UL_PAD_CSI_DATA02__UART5_DCE_RTS 0x1b0b1
MX6UL_PAD_CSI_DATA03__UART5_DCE_CTS 0x1b0b1
>;
};

pinctrl_bt: btgrp {
fsl,pins = <
MX6UL_PAD_CSI_MCLK__GPIO4_IO17 0x17059 /* BT reg enable */
>;
};

...
...

&uart5 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_uart5>;
fsl,uart-has-rtscts;
dma-names = "", "";
status = "okay";
};
...</pre>

== Downloading firmware ==
Now you need to download firmware for Bluetooth module and place it in /etc/firmware directory (note that download link may change in the future, you can find it in documentation section on [[VisionSOM-6ULL|VisionSOM-6ULL Wiki page]]:
<pre>root@somlabs:~# cd ~
root@somlabs:~# wget http://somlabs.com/os_images/visionsom-6ull-bcmfirmware.tar.xz
root@somlabs:~# tar xf visionsom-6ull-bcmfirmware.tar.xz
root@somlabs:~# cp -R ./lib/firmware /etc/
root@somlabs:~# rm -R ./lib
</pre>
== Enabling Bluetooth ==
To enable Bluetooth first you need to reset and attach the module:
<pre>root@somlabs:~# echo 113 > /sys/class/gpio/export
root@somlabs:~# echo out > /sys/class/gpio/gpio113/direction
root@somlabs:~# echo 0 > /sys/class/gpio/gpio113/value
root@somlabs:~# sleep 0.1
root@somlabs:~# echo 1 > /sys/class/gpio/gpio113/value
root@somlabs:~# hciattach /dev/ttymxc4 bcm43xx 3000000 flow -t 20
bcm43xx_init
Set Controller UART speed to 3000000 bit/s
Flash firmware /etc/firmware/1DX_BCM4343W/BCM43430A1.1DX.hcd
Set Controller UART speed to 3000000 bit/s
Device setup complete
</pre>

Now you need to install rfkill tool and disable rfkill block for Bluetooth:
<pre>root@somlabs:~# apt install rfkill
Reading package lists... Done
Building dependency tree
...
...
Setting up rfkill (0.5-1+b1) ...
root@somlabs:~# rfkill list
0: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
1: brcmfmac-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: no
2: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no
root@somlabs:~# rfkill unblock 2
root@somlabs:~# hciconfig hci0 up
</pre>

Now we can check if Bluetooth works:
<pre>root@somlabs:~# hcitool dev
Devices:
hci0 43:43:A1:12:1F:AC
root@somlabs:~# hcitool -i hci0 scan
Scanning ...
XX:XX:XX:XX:XX:XX iPhone (XX)
