It describes the sequence of commands and set-up requirements to quickly evaluate the major functions of the modules. Chapters Using the Evaluation Board in UART mode to Evaluating the Module in Infrastructure mode describe operation using the UART interface. Using the Evaluation Board in SPI mode describes operation using the SPI interface. Upgrading Firmware describes the firmware upgrade procedure. Even if the user does not plan to use the UART interface, it is recommended to go through the UART section because all the set-ups to evaluate different functionalities of the module in UART mode are directly reusable in the SPI mode also.

Redpine Signals, Inc. Page 14 Connect-io-n™ RS9110-N-11-24 Evaluation Board User Guide VVeerrssiioonn 33..1133 3.2 Configure Serial Port Monitor in the PC The actual bytes exchanged between the module and the Host PC may not all be readable on Hyperterminal or Teraterm because of ASCII conversion. A serial port monitor2 can be used to see the actual bytes. A free package is available at http://www.serial-port-monitor.com/ , while other similar software such as Hterm, Docklight etc. also provide good interfaces to simultaneously view ASCII and actual bytes exchanged in the UART interface. The following sections assume that HHD Free Serial Port Monitor has been installed from the above link. Open the “HHD Free Serial Port Monitor” BEFORE opening the Hyperterminal or Teraterm. Click on File -> New Session. Select “Serial Port Monitor”. Select the appropriate COM port and “Request view” for the display format. 2 Redpine Signals Inc. assumes no liability for damages of any kind resulting from use of third party software.

This returns the firmware version in the module. d. at+rsi_scan=0 This command makes the module scan for all channels. e. at+rsi_authmode=3 This command sets the security mode for the module to WPA2-PSK. f. at+rsi_psk=12345678 This command configures the PSK in the module to match that in the Access Point (AP). It is assumed in this example that a WPA2-PSK enabled AP is used, with a key “12345678”. g. at+rsi_join=TEST_AP,0,2 This command is to associate to the Access Point “TEST_AP” h. at+rsi_ipconf=0,192.168.50.10,255.255.255.0,192.168.50.1 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 Hyperterminal, this response might appear as unreadable characters because of ASCII conversion. Serial Port Monitoring software can however be used to see the exact bytes. To get the IP in DHCP mode the command is at+rsi_ipconf=1,0,0,0 It is assumed in the following sections that an IP of 192.168.50.10 has been assigned. i. at+rsi_ltcp=5001 This command opens a listening TCP socket in the module 5. Connect Laptop (C) to the same Access Point and execute ping from it to the module to check basic connectivity. 6. Exchanging data between the PC (P) and Laptop (C) 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 192.168.50.10 5001 The application is found in the path RS.CN.xx.GENR.UT.x.x.x\Software\Applications\Windows. b.

The firmware package for the Wi-Fi module comes with a reference driver in source code form. The reference driver can be ported to the Host MCU platform to interact and operate the Wi-Fi module. The Programming Reference Manual (PRM) is the most important document to help users to operate the module in SPI mode. For comprehensive details on all the SPI commands that can be used to configure, operate and upgrade the module, please refer to the Programming Reference Manual. The set-ups used in the previous sections in UART mode can be used in SPI mode as well. Note: 1.There are two ways of powering the EVB: either use the USB inlet (USB adapter provided with the EVB) OR the pin #4 of the header. 2. Pin # 1 (SDIO_DATA3) should be left open. 3. Pin # 2 (SPI_CS) SPI chip Select 4. Pin # 3 VSS 5. Pin # 4 VDD 6. Pin # 5 (SPI_CLK) SPI Clock 7. Pin # 6 VSS 8. Pin # 7 SPI_DATAIN = MOSI 9. Pin # 8 SPI_DATAOUT = MISO 10.

Redpine Signals, Inc. Page 47 Connect-io-n™ RS9110-N-11-24 Evaluation Board User Guide VVeerrssiioonn 33..1133 Signal Integrity Guidelines for SPI interface: Glitches in the SPI clock can potentially take the SPI interface out of synchronization. The quality and integrity of the clock line needs to be maintained. The following steps are recommended. Please note that this is not an exhaustive list of guidelines and depending on individual cases additional steps may be needed. 1. It is recommended to avoid using cables to connect the Host platform with the module’s SPI interface. In case a cable is used, minimize the length of the SPI bus cable to as small as possible, preferably to within an inch or two 2. It is recommended to use a companion card with a rigid connector to the host 3. If a cable is used, increase the number of ground connections between the WiFi PCB and the MCU PCB 4.1 TCP/IP Stack Usage in RS9110-N-11-24–SPI mode RS9110-N-11-22, RS9110-N-11-24 and RS9110-N-11-28 are Wi-Fi modules with integrated TCP/IP stack. This reduces the development effort for designers who don’t want to integrate a TCP/IP stack in their Host platform. However, there are applications where the designer wants to run his own TCP/IP stack on the Host. The TCP/IP stack in the mentioned modules can be bypassed in such scenarios. This feature of bypassing the stack is available from firmware version 4.5.0 onwards. 4.1.1 Using the Wi-Fi module with TCP/IP stack enabled The Wi-Fi module is by default in “TCP/IP stack enabled” mode. 1. The reference driver that the user should use for this mode is placed inside RS.CN.xx.GENR.SP.x.x.x/Driver/Driver_TCP 2. The API manual that should be used is placed in RS.CN.xx.GENR.SP.x.x.x/Driver/Driver_TCP/Documentation/
Redpine Signals, Inc. Page 48 Connect-io-n™ RS9110-N-11-24 Evaluation Board User Guide VVeerrssiioonn 33..1133 Figure 14: Architecture with TCP/IP Enabled 4.1.2 Using the Wi-Fi module with TCP/IP stack bypassed The TCP/IP stack in the WiFi module can be bypassed by sending a software command from the Host to the module. The “TCP bypass command” should be issued to convert the RS9110-N-11-24 from a TCP/IP enabled module to a TCP/IP bypassed module. The following should be taken care of: 1. The reference driver that the user should use for this mode is placed inside RS.CN.xx.GENR.SP.x.x.x/Driver/Driver_TCP_Bypass 2. The API manual that should be used is placed in RS.CN.xx.GENR.SP.x.x.x/Driver/Driver_TCP_Bypass/Documentation/ 3. In this mode, the WiFi module presents itself as a standard network interface, which would talk to the Host TCP/IP stack through the network driver in the Host. For transmitting data to the air interface, the data should be framed by the TCP/IP stack in the Host as an Ethernet frame, and the WiFi module does only the WLAN framing on top of it. The interface is according to standard networking protocols. For example : http://www.makelinux.com/ldd3/chp-17-sect-3 describes the structure for Linux. For successful sending and receiving of data, the MAC ID of the module should be assigned to a field inside the net_device structure

Once this is stored after association with AP, the user can bring the wlan interface up In Linux, this is usually done by: ifconfig wlan0 <ipaddr> ifconfig wlan0 up The user can query wlan0 interface status using: ifconfig wlan0 The Redpine Module’s MAC address should be listed in the HW Addr (00:23:A7:xx:xx:xx) Figure 15: Architecture with TCP/IP Bypassed 4.2 SPI Operations The SPI operations with the TCP/IP stack enabled in the module are shown below.
