== How to setup Marvell bluetooth ==
=== Overview of How-To ===
This How-To is meant to be a starting point for people to learn setup the bluetooth on IGEP v2 devices as quickly and easily as possible.
=== Feedback and Contributing ===
At any point, if you see a mistake you can contribute to this How-To.
=== Setup basics ===
The IGEP v2 has built-in a Class 2 Bluetooth 2.0 + EDR device.

By default the WIFI-BT module is not configured for single antenna, so you need to configure this, set registers settings as follows:

<pre>
# mount -t debugfs none /sys/kernel/debug
# cd /sys/kernel/debug/lbs_wireless/eth1/registers/
# echo "0xa58c 0x40865" > wrmac
# echo "0xa5a0 0xd24d" > wrmac
# echo "0xa5f0 0xa027181c" > wrmac
</pre>
Next, you will need to load some bluetooth modules
<pre>
# modprobe bluetooth
# modprobe hci_uart
# modprobe l2cap
# modprobe rfcomm
# dmesg
Bluetooth: Core ver 2.13
NET: Registered protocol family 31
Bluetooth: HCI device and connection manager initialized
Bluetooth: HCI socket layer initialized
Bluetooth: L2CAP ver 2.11
Bluetooth: L2CAP socket layer initialized
Bluetooth: BNEP (Ethernet Emulation) ver 1.3
Bluetooth: BNEP filters: protocol multicast
Bluetooth: RFCOMM socket layer initialized
Bluetooth: RFCOMM TTY layer initialized
Bluetooth: RFCOMM ver 1.10
</pre>
With your preferred editor create a bluez.psr file like this
<pre>
// PSKEY Parameters for Bluetooth RF
// (1) 0x0031 (PSKEY_LC_ENHANCED_POWER_TABLE)
&0031 = 0900 0000 3f00 4700 ec00 0f00 0000 3f00 4a00 f000 1600 0000 3f00 4d00 f400 1e00 0000 \
3f00 5000 f800 2600 0000 3f00 5500 fc00 2e00 0000 3f00 5b00 0000 3800 0000 3f00 6900 0400
// (2) 0x01f6 (PSKEY_ANA_FTRIM)
&01f6 = 001d
// (3) 0x01fe (PSKEY_ANA_FREQ)
&01fe = 6590 // 26MHz reference clock
// (4) 0x01be (PSKEY_UART_BAUDRATE)
&01be = 0x1d8 // 115200
// (5) 0x0028 (PSKEY_LC_COMBO_DISABLE_PIO_MASK)
&0028 = 0200 0000 0000
// (6) 0x002a (PSKEY_LC_COMBO_DOT11_CHANNEL_PIO_BASE)
&002a = 0011
</pre>
And send the file using the bccmd tool.
<pre>
# bccmd -t bcsp -d /dev/ttyS1 psload -r bluez.psr

Finally you can attach to device an scan for other bluetooth devices.

For best performance you need to disable WIFI, you can do this
<pre>
