  • Page 5: Wsn802G Introduction

    The WSN802G transceiver module is a low cost, robust solution for 802.11b/g/n sensor networks. The WSN802G is unique in that it is able to sleep while still remaining a member of an 802.11b/g/n network. The WSN802G’s low active current and very low sleep current makes long life battery operation practical.

  • Page 6: Features

    The sensor network application on the server or PC uses a simple protocol to send and receive data from WSN802G sensor nodes, as detailed in Section 4. WSN802G modules can receive configura- tion commands through either their serial port or over-the-air in UDP packets carrying SNMP commands.

  • Page 7: Wsn802G Operation

    2.1 Active and Sleep Modes Once the SNMP Server IP address has been set, the default state of the WSN802G is sleep mode. The WSN802G has a dedicated input to switch it from sleep to active mode, WAKE_IN (Pin 26). There are five events that will wake the WSN802G from sleep mode: •...

  • Page 8: Automatic I/O Reporting

    Whenever the module is in active mode, a logic high is asserted on WAKE_OUT (Pin 27). WAKE_OUT can be used to signal an external processor. When the WSN802G is in sleep mode, WAKE_OUT is set to logic low. 2.2 Automatic I/O Reporting The WSN802G sends an I/O report when one of the following events occur: •...

  • Page 9: Analog I/O

    Figure 2.5.2 2.6 Analog I/O The WSN802G includes two 10-bit ADC inputs, ADC0 (Pin 18) and ADC1 (Pin 19). Pin 25 provides a full- scale reference voltage to support ratiometric ADC measurements. ADC measurements are triggered and added to the automatic I/O report when a logic high signal is first applied to the WAKE_ IN pin or the Au- toReport timer fires, as discussed in Section 2.2.

  • Page 10: Digital I/O

    Section 4.4. 2.7 Digital I/O The WSN802G includes four general purpose input/output (GPIO) ports, GPIO0 (Pin 4), GPIO1 (Pin 11), GPIO2 (Pin 10) and GPIO3 (Pin 12). When programmed as inputs, GPIO pins include an internal weak pull-up.

    2474 MHz, with a nominal RF output power of 10 mW. WSN802G modules support four standard 802.11g RF data rates, 1, 2, 5.5 and 11 Mbps. WSN802G modules provide a variety of hardware inter- faces. There are two serial interfaces, one for data and a second for diagnostics. The data port supports standard serial baud rates from 1.2 to 921.6 kbps, and the diagnostic port supports standard serial baud...

  • Page 38: Ip Address Discovery Protocol

    5.0 IP Address Discovery Protocol The WSN802G module supports a separate UDP client port that provides a discovery protocol for wire- less communications. The discovery protocol is used to find IP addresses of modules in a network when the IP addresses have been assigned by a DHCP server. The discovery protocol is also used to set the module’s SNMP Server IP addresses which enables module commissioning.

    The WSNConfig utility included with the developer’s kit is designed to operate as a commissioning utility for the WSN802G. The WSNConfig utility allows for each node to be configured independently or as a whole. Individual settings may be configured or a list of configuration parameters can be queued for transmission when the node or nodes wake up and issue the Config Trap.

In a few moments the IP address of the WSN802G module will be displayed near the top of the left hand text box on the WSNConfig window, as shown in Figure 8.3.3. If the module IP address does not appear, see Section 8.4 below.

    WSN802G module is associated with the access point. If the WSN802G module is not associated with the access point, check for an RF issue such as a loose antenna connection. If the WSN802G module is associated with the access point, there is something blocking module IP address discovery in the host PC.

    Clicking the Refresh button loads the configuration parameters from the local buffer into various tabs in the Config dialog box. Clicking the Get All button queues a request to the WSN802G module to send a new copy of all its con- figuration parameters. How quickly the module responds depends on the ConfigTrapInterval system pa- rameter and when in the trap interval the request was queued.
  • Page 76 How quickly the module responds depends on the ConfigTrapInterval sys- tem parameter and when in the trap interval the request was queued. The IP Address in the lower left of each tab in the Config dialog box is the WSN802G module IP address. Figure 8.6.2 The first Network tab displays basic network parameters information.
