# Service Daemon and CLI
3
The location service offers a daemon executable and a corresponding
4
command-line interface for interacting with it. The daemon does not
5
necessarily require root privileges, but might so depending on your
8
Run the following command to receive an overview of the arguments to
11
ubuntu-location-serviced --help
13
An example invocation of the daemon, configuring a GPS provider that
14
relies on the Android HAL to talk to the chipset, exposing the service
15
on the system DBus instance:
17
ubuntu-location-serviced --bus system --provider gps::Provider
19
The cli allows for querying properties of a running service instance, e.g.:
21
ubuntu-location-serviced-cli --bus system --get --property is_online
23
## Configuring an Out-Of-Process Provider
25
If you want to run a provider out of process, the daemon executable
26
allows you to do so by instantiating a so-called remote provider. The
27
following invocation of the service tries to connect to the provider
28
instance described by the given unique DBus name and path.
30
ubuntu-location-serviced \
32
--provider remote::Provider \
33
--remote::Provider::bus=system \
34
--remote::Provider::name=com.ubuntu.location.provider.Gps \
35
--remote::Provider::path=/
37
Please note that the service allows for decorating provider names to
38
uniquely identify per provider configuration options and to allow for
39
loading more than one provider of a certain kind. The following
40
configuration configures two remote providers, one relying on GPS
41
(decorated with @gps) and another one relying on network-based
42
positioning (decorated with @network):
44
ubuntu-location-serviced \
46
--provider remote::Provider@gps \
47
--remote::Provider@gps::bus=system \
48
--remote::Provider@gps::name=com.ubuntu.location.provider.Gps \
49
--remote::Provider@gps::path=/ \
50
--provider remote::Provider@network \
51
--remote::Provider@network::bus=system \
52
--remote::Provider@network::name=com.ubuntu.location.provider.Network \
53
--remote::Provider@network::path=/
