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

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

=== Switch-off wifi to get better bluetooth performance ===
For best performance you need to disable WIFI, you can do this:<br><br>Disable wlan0 interface<pre>ifconfig wlan0 down</pre> Switch-off "power down" line of wifi* For IGEPv2 RevC ('''IGEP0020-RC''') and IGEP COM MODULE ('''IGEP0030-RE''') series <pre>echo 0 > /sys/class/gpio/gpio138/value</pre> * For older IGEPv2 RevB ('''IGEP0020-RB''') series
