You might have an easier time getting this to work if you create a shell script as root that does what you want. Then set it up in sudo to be so that certain user can run it with sudo, but not edit it.

This is what i said at first. IMHO this would solve all the troubles once and for all.

sleep 1

Error:

Code:
embdesnithin@embdesnithin:~$ sudo sh ble_connect_write.sh 
su: invalid option -- 'i'

I suppose this is just a matter of correct quoting:

Code:
su - embdesnithin -c "hcitool -i hci0 lecc --random EA:74:48:D5:52:6B"

Note the double quotes around the command, analoguous for the other lines.

You should, btw., not use these long options, i.e. "--command" instead of "-c". This only works with the GNU versions of commands, not with the standard command. This way you unnecessary limit the portability of your script.

"/bin/sh" is on most systems a call to the systems default shell which i used as a stand-in. As you seem to work on a Linux-System this should call a bash.

I hope this helps.
