RS-WC-301 Evaluation Board User Guide Version 2.51 1 Introduction This document describes how to use the RS-WC-301 EVB. It describes the sequence of commands and set-up requirements to quickly evaluate the major functions of the modules. The document should be used in conjunction with the Programming Reference Manual (PRM) where all commands to configure and operate the modules are described in detail.
RS-WC-301 Evaluation Board User Guide Version 2.51 2 Components on the EVB The RS-WC-301 EVB has various switches and headers to enable the user to configure it for different scenarios. Figure 1: RS-WC-301-EVB USB Connector for Power The power for the board can be supplied through this connector. Note that this connector is used only for supplying power. For actual communication using USB, the USB interface described below is used.
RS-WC-301 Evaluation Board User Guide Version 2.51 If the EVB needs to be connected to the serial interface of an MCU platform, this header can be used. The voltage level of the UART Tx and Rx pins of this header is 3.3V. The Ground pin should be connected to a corresponding ground signal of the MCU board.
RS-WC-301 Evaluation Board User Guide Version 2.51 The LED indicates that wireless data transfer activity is in progress. This LED is not used in the current firmware. General Purpose Header Pin number 1 Pin name SPI_READY Direction Output 2 3 NC RESET_N Input 4 5 NC WAKEUP Input 6 PT_GPIO2 Output 7 ADC2 Input 8 PT_GPIO1 Output 9 10 GND VCC Power 11 ADC1 Input Redpine Signals, Inc. Description Handshake signal used in SPI mode and connected to a GPIO pin of the Host MCU.

When BT coexistence is not used, this pin should be grounded No connect Used for BT Coexistence. It indicates with logic high that WLAN activity is in progress. When low, BT device has the opportunity to transmit.
RS-WC-301 Evaluation Board User Guide Version 2.51 9 10 GND VCC Power 11 12 13 NC NC BT_PRIORITY Input 14 15 NC WLAN_ACTIVE Output 16 17 18 19 20 NC NC NC NC GND - be left open Ground 3.3V power supply. If the USB port for power supply is not used, this pin can be used to drive power to the EVB from the Host MCU platform. The direction of the “Power Selection” switch is ignored in this case. The maximum current sourcing capacity of the Host should be 500mA.
RS-WC-301 Evaluation Board User Guide Version 2.51 6 7 8 9 10 GND SPI_MOSI SPI_MISO INTERRUPT Input Output Output NC - MHz Ground SPI data input SPI data output Active high, level triggered interrupt, used in SPI mode. The interrupt is raised by the module to indicate there is data to be read by the Host, or to indicate the module has woken up from sleep. In UART mode, it can be left open No connect Table 5: SPI Header Pins UART Interface Selection These switches are present in RS-WC-301-EVB.
RS-WC-301 Evaluation Board User Guide Version 2.51 Table 6: Sensor Interface Header USB Interface This is a USB 2.0 interface and is supported in firmware version 2.0.0.1.2.4 and above. Jumper The jumper shown in some versions of the EVBs can be used for measurement of current consumed by the module. NOTE: EVB Versions below 3.1 do not support Power Save Mode 3 (Refer to Programming Reference Manual version 1.9 or higher for definition of this mode). 2.
RS-WC-301 Evaluation Board User Guide Version 2.51 3 Using the EVB in UART mode The following sections describe how to use the Evaluation Board in UART mode. The sections should be used in conjunction with the Programming Reference Manual to understand the commands better. 3.1 Configure Serial port in PC To know the COM port name, check the computer‟s Device Manager settings. The COM port name is displayed in the window.

RS-WC-301 Evaluation Board User Guide Version 2.51 Figure 3: Access Point Settings (Personal Security Mode) Redpine Signals, Inc.
RS-WC-301 Evaluation Board User Guide Version 2.51 4.1 Configuration and Test Procedure 1. Configure the EVB in UART mode and connect a UART cable between the PC and the EVB. 2. Open the Serial Port Monitor to see the actual bytes exchanged. Open Hyperterminal or Teraterm with the settings described in section Configure Serial port in PC. 3. Supply power to the EVB through the USB connector and put the “Power Selection Switch” to the position as shown in the figure Error! Reference source not found.. 4.
RS-WC-301 Evaluation Board User Guide Version 2.51 This command configures the module‟s IP to 192.168.50.10 in static mode. Make sure the desired IP is in the same subnet as the Access Point. The module responds to this command by sending the configured IP address to the Host as response to the command. In the terminal, this response might appear as unreadable characters because of ASCII conversion. The Serial Port Monitor can however be used to see the exact bytes.
RS-WC-301 Evaluation Board User Guide Version 2.51 5. Connect the Laptop C (Windows XP/Vista/Windows7) to the Access Point. It is assumed for the rest of this section that the Laptop has acquired an IP address of 192.168.50.20. 6. Exchanging data between the module and the Laptop C Using TCP Sockets a. Open a TCP socket in the Laptop C by typing the below command in the Windows command line interface. Make sure that any firewalls, that might prevent opening of sockets, are disabled. TCP.exe c 2001 192.168.
