This section is pending for approvals from FCC and IC " Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication." " Conformément à la réglementation d'industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante." " This radio transmitter (iw-smg3smts-ex or -OB) has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device." " Le présent émetteur radio (iw-smg3smts-ex or -OB) a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et ayan un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur." " This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device." " Le présent appareil est conforme aux CNR d'industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement." Antennas: Air Wave (EA-79F); Tekfun C. (M04-SR); YC Communication (Q24-24W); Pulse (W1030). Maximum Gain all: 2dBi. 2

6 1. Introduction 1) General Description iw-smg3smts-ard is a secure WiFi Arduino shield, that can perform as a WiFi client or access point to connect the Arduino microcontroller board to b/g/n Wireless LANs. It includes Connect One s Pico WiReach WiFi module, containing an ARM 32-bit Cortex-M4 CPU and a Cypress CYW43362 WiFi chipset, and Connect One s embedded software featuring an extensive AT+i command set. The iw-smg3smts-ard offers and supports many features among them: WiFi client and access point modes Out of the Box Sensors connectivity and Sensor to Cloud capabilities Ten simultaneous TCP/UDP sockets SSL3 and TLS 1.2 security WEP, WPA, WPA2 and Enterprise (RADIUS) Two listening sockets Webserver with two websites - Internal for module configuration and host SMTP and POP3 clients DHCP client/server POP3 SMTP client with MIME attachment FTP client iw-smg3smts-ard supports the SSL3/TLS1.2 protocol for secure sockets, HTTPS, FTPS and secure web server. On the WLAN interface, it supports WEP (station mode only), WPA and WPA2 WiFi encryption and Enterprise level security. Together with a standard Arduino microcontroller board, iw-smg3smts-ard is an easyto-use evaluation board. A sample of an Arduino program, once downloaded into the Arduino, shows a simple example of WiFi client and access point implementation. Also, provided, a simple serial pass-through application that once downloaded to the Arduino, allows AT+i commands from a computer to be sent through the Arduino microcontroller to the Pico WiReach for direct access to the WiFi module. For more information about the Pico WiReach and the AT+i command set, please refer to the Support area on Connect One s website 6

13 /* Appendix 1 Arduino Demo Program Connecting to a Local Access Point Software for SMG3SMTS-Ard ConnectOne Arduino Shield The Arduino microcontroller board initializes the SMG3SMTS-Ard board by sending WiFi SSID, Password and Security Method. After scanning for the local access point with the relevant credentials, an IP address received from the local DHCP server PAY ATTENTION: SMG3SMTS_Ard serial baud rate is set to Do not change the baud rate. If you use the AT+IFD (Factory Default) command which changes the baud rate to , you must send AT+IBDRF=7 (to set the baud rate back to 38,400) command before reset or power down. Note: Not all pins on the Mega and Mega 2560 support change interrupts, so only the following can be used for RX: 10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69 Not all pins on the Leonardo and Micro support change interrupts, so only the following can be used for RX: 8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI). This example code is in the public domain. */ #include <SoftwareSerial.h> SoftwareSerial PicoSerial(10, 11); // RX, TX String ssid; String password; String wst0; String ping; String ip; String Stemp; char temp; void setup() { //0-None,1-WEP64,2-WEP128,3-WPA/PSK,4-WPA2/PSK,5-WPA/Ent,6-WPA2/Ent // Open serial communications and wait for port to open: Serial.begin(9600); //init PC serial to 9600 while (!Serial) { ; // wait for serial port to connect.
