Im trying to set this up for my ipad. I find the wifi hotspot programmes really unreliable.

Im having a couple of issues with the installation. I have skipped steps 4.1 to 4.3 as Im assuming the DUP application on the ipad covers this?? However the issue is - I have created the script "bluetooth-pan.sh" ie saved the scriped in notepad and renamed it to bluetooth-pan.sh.
Copied it into the correct folder over SSH. Then in terminal at step 4.3.2 have typed in the code but nothing seems to happen, the same for 4.3.3. I have tried both in root and both not.
Do you have any idea what I could be doing wrong?

PS I have the latest power-kernel installed and bluetooth 'on'.
