## Detailed Description

Wireless Sensor Networks.

The WSN interface provides access to a Wireless Sensor Network (driver implementations include WSN's such as Crossbow's MICA2 motes and TeCo's RCore particles).

The current implementation supports a single group of network nodes. Support for multiple groups will be added in the future.

## Macro Definition Documentation

#define PLAYER_WSN_REQ_DATAFREQ 3

Request/reply: change the receiving data frequency.

#define PLAYER_WSN_REQ_DATATYPE 2

Request/reply: change the data type to RAW or converted metric units.

#define PLAYER_WSN_REQ_POWER 1

Request/reply: put the node in sleep mode (0) or wake it up (1).

## Typedef Documentation

typedef struct player_wsn_cmd player_wsn_cmd_t

Command: set device state (PLAYER_WSN_CMD_DEVSTATE) This `wsn` command sets the state of the node's indicator lights or its buzzer/sounder (if equipped with one).

typedef struct player_wsn_data player_wsn_data_t

Data (PLAYER_WSN_DATA)

The WSN data packet describes a wireless sensor network node.

typedef struct player_wsn_datafreq_config player_wsn_datafreq_config_t

Request/reply: Change data delivery frequency.

By default, the frequency set for receiving data is set on the wireless node. Send a PLAYER_WSN_REQ_DATAFREQ request to change the frequency. Fill in the node ID or set -1 for all nodes. Null response.

typedef struct player_wsn_datatype_config player_wsn_datatype_config_t

Request/reply: change the data type to RAW or converted engineering units.

Send a PLAYER_WSN_REQ_DATATYPE request to switch between RAW or converted engineering units values in the data packet. Null response.

typedef struct player_wsn_node_data player_wsn_node_data_t

Structure describing the WSN node's data packet.

typedef struct player_wsn_power_config player_wsn_power_config_t

Request/reply: Put the node in sleep mode (0) or wake it up (1).

Send a PLAYER_WSN_REQ_POWER request to power or wake up a node in the WSN. Null response.
