=== Overview of How-To ===
This How-To is meant to be a starting point for people to learn how to setup the bluetooth on IGEP v2 Technology 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 bluetooth internal parameters ===
By default the WIFI-BT module is not configured for single antenna, so you need to configure this, set registers settings as follows:
You need to be root to do this - sudo won't do!

=== Load PSKEY parameters ===With your preferred editor create a 'bluez.psr ' file like this:
<pre>
// PSKEY Parameters for Bluetooth RF
And send the file using the bccmd tool.

=== Load Linux kernel modules ===
Next, you will need to load some bluetooth modules. Prompt:
<pre>
modprobe bluetooth
modprobe hci_uart
modprobe hidp
modprobe l2cap
modprobe rfcomm

You shoud get these logs ( using [[IGEP_firmware_Yocto|IGEP Firmware Yocto 1.2.2-3]] ):
