Generic Location Client
The Generic Location Client model can get and set the state of a Generic Location Server model remotely.
Unlike the Generic Location Server model, the Generic Location Client only creates a single model instance in the mesh composition data. The Generic Location Client may send messages to both the Generic Location Server and the Generic Location Setup Server, as long as it has the right application keys.
Extended models
None.
Persistent storage
None.
Shell commands
The Bluetooth mesh shell subsystem provides a set of commands to interact with the Generic Location Client model instantiated on a device.
To make these commands available, enable the following Kconfig options:
- mdl_loc instance get-all
Print all instances of the Generic Location Client model on the device.
- mdl_loc instance set <elem_idx>
Select the Generic Location Client model instantiated on the specified element ID. This instance will be used in message sending. If no model instance is selected, the first model instance found on the device will be used by default.
elem_idx
- Element index where the model instance is found.
- mdl_loc global-get
Get the current global location value of the Generic Location state.
- mdl_loc global-set <latitude> <longitude> <altitude>
Set the global location value of the Generic Location state and wait for a response.
latitude
- Global WGS84 North coordinate in degrees.longitude
- Global WGS84 East coordinate in degrees.altitude
- Global altitude above the WGS84 datum in meters.
- mdl_loc global-set-unack <latitude> <longitude> <altitude>
Set the global location value of the Generic Location state without requesting a response.
latitude
- Global WGS84 North coordinate in degrees.longitude
- Global WGS84 East coordinate in degrees.altitude
- Global altitude above the WGS84 datum in meters.
- mdl_loc local-get
Get the current local location value of the Generic Location state.
- mdl_loc local-set <north> <east> <altitude> <floor> [time_delta [precision_mm [is_mobile]]]
Set the local location value of the Generic Location state and wait for a response.
north
- Local north position in decimeters.east
- Local east position in decimeters.altitude

- If present, defines the time since the previous position update in milliseconds.precision_mm
- If present, defines the precision of the location in millimeters.is_mobile
- If present, defines whether the device is movable.
- mdl_loc local-set-unack <north> <east> <altitude> <floor> [time_delta [precision_mm [is_mobile]]]
Set the local location value of the Generic Location state without requesting a response.

Defines
-
BT_MESH_LOC_CLI_INIT(_handlers)
Initialization parameters for a Generic Location Client model instance.
- Parameters
_handlers – [in] Pointer to a bt_mesh_loc_cli_handlers instance.

Functions
-
int bt_mesh_loc_cli_global_get(struct bt_mesh_loc_cli *cli, struct bt_mesh_msg_ctx *ctx, struct bt_mesh_loc_global *rsp)
Get the global location of the bound srv.
This call is blocking if the
rsp
buffer is non-NULL. Otherwise, this function will return, and the response will be passed to the bt_mesh_loc_cli_handlers::global_status callback.- Parameters
cli – [in] Client model to send on.
ctx – [in] Message context, or NULL to use the configured publish parameters.
rsp – [out] Global Location response buffer, or NULL to keep from blocking.
- Return values
0 – Successfully sent the message and populated the
rsp
buffer.-EALREADY – A blocking request is already in progress.
-EADDRNOTAVAIL – A message context was not provided and publishing is not configured.
-EAGAIN – The device has not been provisioned.
-ETIMEDOUT – The request timed out without a response.
-
int bt_mesh_loc_cli_global_set(struct bt_mesh_loc_cli *cli, struct bt_mesh_msg_ctx *ctx, const struct bt_mesh_loc_global *loc, struct bt_mesh_loc_global *rsp)
Set the Global Location in the server.
This call is blocking if the
rsp
buffer is non-NULL. Otherwise, this function will return, and the response will be passed to the bt_mesh_loc_cli_handlers::global_status callback.- Parameters
cli – [in] Client model to send on.
