[MT] a couple things here, first, should the attrib_db_add function
allow input parameters "wgardrite_cb" and "read_cb"?
second, should this function register a write_cb for immediate
alert characteristic? so if the client writes a value to this
characteristic, the write_cb can be called? And I think a signal will
be sent to application that has registered with immediate alert
service?
Regards,
Mike
