the Bluetooth status is always uint8_t and I think it is a good idea to
map these error codes directly. We can define our own codes from 0xff
onwards if we use a uint16. However we should try to use the Bluetooth
defined errors whenever possible.

A string would be nice, but in generell these are useless. However for
application that doesn't consider internationalization it will be easy
for them to display the errors in clear text.

Marcel
