Implement only the first interaction of the discovery procedure. If the
response doesn't fit in the MTU, "start" and "end" options can be used
to discover the handles ranges of the remaining primary service instances.
UUID16 and UUID128 are supported in the uuid option.
Usage example:
$gatttool -i hcix -b xx:xx:xx:xx:xx:xx --uuid=1801 --primary
