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.

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).

Data (PLAYER_WSN_DATA_STATE)

The WSN data packet describes a wireless sensor network node.

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.

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.

Structure describing the WSN node's data packet.

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.
