Has anyone tried to create an app/driver to allow a bluetooth usb dongle to be used on an android device, which does not already have bluetooth? I have a tab which has android 4.0.4 and the system information app says that it supports bluetooth, however there is no bluetooth mention in the settings for wifi etc. What information can anyone give regarding what would be involved in writing a driver/app to be able to use a usb BT dongle.
