Hardware

Power supply

GW-ETH-02A should be supplied via standard micro USB connector by external stabilized 5 V DC, e.g. from the power source delivered with the GW or from USB interface.

Ethernet

Ethernet/LAN line should be connected via standard 8-pin RJ-45 connector.

Pushbuttons

Both Reset and Control pushbutton functionality is fixed and can not be changed in application program.

Control

• Short press (< 1 s): no effect

• Long press (>1 s, < 10 s): GW off

• Long press (> 10 s): restore the factory settings of the gateway. (After 10 s all LEDs get off to indicate that the factory setting was restored.)

Reset

Reset button can be pressed by a pin through the hole in the case. It is intended to reset the gateway (equally to switching the GW power supply off and on). Current GW configuration stays unchanged. For reinitializing the GW (to restore the factory settings), use menu Maintenance → Factory Defaults at Web server.

LEDs

See Appendix 1 – LED indication.

IQRF

DCTR-52DA or DCTR-72DA wireless transceiver module is used for IQRF connectivity. Antenna is built in DCTR module.

GW-ETH-02A

Flash memory

Log data is stored in circular buffer in Flash memory. When it is full and a subsequent write is performed, then it starts overwriting the oldest data.

There is 252 KB dedicated to IQRF RX data and 128 KB for IQRF TX data and same size for System log.

The number of records of IQRF RX/TX data depends on the parameter Packet size, which define how many payload data bytes is dedicated for every data record. For default setting ( Packet size = 64 B) there is 3308 positions for IQRF RX and 1680 positions for IQRF TX. For System log there is always 6553 positions in the buffer.

The actual size of the data log is the Packet size + 14 B, where the additional 14 bytes are used for saving date, time and index of the log. In this way the user can calculate actual number of positions in the buffer.

Data volumes and recording frequency must be taken in account with respect to the Flash memory endurance.

When the Packet size is changed in the GW settings, all logs are cleared.

Case

Caution: It is not allowed to open the GW case otherwise the device may be damaged.

GW-ETH-02A

Operation

Start up

GW-ETH-02A is turned on by USB power supply connecting.

Initialization

• After the start-up, the GW checks its own hardware first. If there is no critical error it starts to initialize Ethernet.

When a critical error occurs, the execution does not continue and the error code is indicated by LEDs.

Communication

The size of payload IQRF data transmitted between the GW and the IQRF network is limited to 64 B in both directions.

GW-ETH-02A can work in the following modes:

Datalogger mode

• All incomming IQRF data (IQRF RX) is stored and logged in internal Flash memory. When used with IQRF Cloud,

the logged data is transmitted to the Cloud server always after the Cloud period elapsed. See chapters IQRF IDE – GW Tool and Web server.

• Data to be sent to IQRF (IQRF TX) is stored in internal Flash memory. When used with IQRF Cloud, the data is

stored in the Cloud server first, transferred to the GW always after the Cloud period elapsed and then forwarded to IQRF network.

• If the communication between the GW and the Cloud server failed, the GW indicates an error.

Gateway mode

• Direct connection between IQRF networks and remote device via UDP channel is established.

• The communication uses a specific application protocol, see chapter Application protocol for UDP channel.

• Errors in communication between the GW and the remote device should be solved by the user application.

Page 7

GW-ETH-02A

Using IQRF IDE

• The IQRF IDE GW Tool is intended for GW configuration, checking of operational and error states and for access to the datalogger. When using the GW Tool, the communication via Ethernet is enabled.

• Additionally, IQRF IDE can be used similarly as for the CK-USB-04(A): uploading the code into TR transceiver,

configuration of TR module inside the GW, debugging of the application, using the IQMESH Network manager etc. In this mode the communication via Ethernet is disabled.

Internal web server

To get connected to the internal web server it is necessary to know IP address of the GW or the GW host name (if the network supports the NBNS, i.e. within the LAN only). Internal web server is used for GW configuration (manually in graphic environment or by loading a binary file *.gwcnfg), datalogger reading (TX, RX, System log), TR module programming (*.hex, *.iqrf, *.trcnfg) and FW upgrading (gweth.hex). When uploading any of these files, it is necessary to have SD card plugged in the GW card slot, otherwise the operation can not be completed.

GW configuration

GW configuration is possible via internal www server, IQRF IDE or (especially for troubleshooting) via SD card.

Page 8

GW-ETH-02A

SD card file structure

The SD card is intended for development, service and maintenance. It should be accessed primarily by the GW while direct writing by the user (externally by a standard SD card reader/writer) is recommended for exceptional purposes only. The standard way to perform required changes is using the internal web server.

The SD card uses the following folders:

• Root The root directory is intended for a new FW (gweth.hex file) to be used for upgrade.

• TRUPLOAD The folder intended for files to be uploaded into the TR module (*.hex, *.iqrf, *.trcnfg).

• GWCNFG The folder intended to record a new GW configuration (*.gwcnfg).

• BACKUP The folder intended for current GW configuration (gw.gwcnfg).

When using the web server, all folders and files are created automatically when required. In case of external direct writing the required folders must be created by the user. Files not necessary any more are automatically deleted after the usage.

System log

All important events are logged. System logs can be read using IQRF IDE GW Tool or the GW web interface.

Date and time

GW-ETH-02A contains a real time clock/calendar (RTCC). Date and time are synchronized using SNTP/Cloud server.

TR module data exchange

Data between the internal TR module and the GW memory is transferred bidirectionally via SPI (using the bufferCOM memory array inside the TR module). Therefore, the application in TR must have the SPI communication activated. When using DPA, a hardware profile with SPI interface must be uploaded in TR. Such plug-in is uploaded from the factory. The maximum SPI packet length is 64 B.

Ethernet services

• HTTP client for communication with IQRF Cloud server (using the 128 b AES encryption)

• HTTP server offering web pages for remote management via a common browser

• HTTP client for getting and updating of public address from DDNS

• UDP server/client for communication with IQRF network and for remote GW management

• SNTP client for getting date and time from time server

• ICMP server allowing “ping” to GW from a remote host

• DHCP client for automated getting of IP address from the DHCP server

• NBNS server for using names instead of IP addresses within the LAN

GW identification

MAC address

Every device has a unique MAC address in the format 00 1F D5 xx xx xx, where:

• 00 1F D5 is the OUI dedicated to MICRORISC s.r.o.

• xx xx xx is a device serial number

Actual MAC address is printed on the label at the bottom of the GW-ETH-02A case.

Another unique number (manufacturer's identification) used to identify the gateway by IQRF IDE, the IQRF Cloud server and user applications utilizing the Cloud via API.

For GW-ETH-02A: ID = 12 xx xx xx, where xx xx xx are last 6 digits of the MAC address.

NBNS Name

iqrf_xxxx, where xxxx are the last 4 digits of the MAC address.

GW-ETH-02A

IQRF Cloud

The IQRF Cloud provides an effective way to exchange data between IQRF wireless device(s) and a user superordinary system implemented by a higher level platform (e.g. PHP, JavaScript or web interface) and connected via Internet or a LAN.

As an interface to IQRF, the GW-ETH-02A or another IQRF gateway providing Internet connectivity (Ethernet, GPRS or WiFi) is intended.

An IQRF Cloud server is available free of charge on http(s)://cloud.iqrf.org provided by CIS (Complete Internet Services, s.r.o., an IQRF contractual partner for cloud solutions). Moreover, a licensed version is available for every user of an IQRF gateway prefering to implement and operate one's own IQRF Cloud. Refer to the IQRF Cloud User's Guide for details.

First startup

Factory settings

GW-ETH-02 is set from the factory as follows:

• User name iqrf

• Password iqrf

• Operation mode Datalogger

• IQRF Cloud Enabled

• IQRF Cloud hosting By CIS (https://cloud.iqrf.org)

• Communication period 10 s

This setting can be used to operate the GW with IQRF Cloud without any changes in configuration. But it is strictly recommended to change the GW password to avoid illegal access to GW data.

Step by step guide

To get familiar with GW-ETH-02A functionality, the GW can be used with DPA hardware profile in similar way as which is described in IQRF DPA Quick Start Guide:

• Follow this Guide, chapters 1 to 5.

• Use GW-ETH-02A instead of CK-USB-04(A)

• GW-ETH-02A is delivered with the GeneralHWP-Coordinator-STD-SPI plug-in uploaded in internal TR module.

Thus, there is no need to upload any HWP plug-in.

• After LED control testing from IQRF IDE via USB according to chapter 5 mentioned above, test the same

commands via Ethernet:

• Disconnect the GW from IQRF IDE or go to IQRF IDE GW Tool.

• Open the https://cloud.iqf.org page in web browser

Page 28

GW-ETH-02A

• Create your user account there and login to this

• Add the GW to the List of gateways assigned to your account by the Add gateway button. The GW ID and the

password must be entered.

• Open the main page of the GW by clicking to the GW ID number

• Click the Send data to IQRF button. The window with predefined LED control commands opens.

• Using the macros or by modification of commands in IQRF Tx field and the Send button you can control LEDs in

individual or all nodes similarly as before (by using IQRF IDE).

Page 29

GW-ETH-02A

Application protocol for UDP channel

The communication is realized with the application protocol described below. It uses the transport protocol UDP according the OSI reference model. For establishing a connection it is necessary to know the UDP port where the GW is listening and its IP address or the NetBIOS name (Host Name).

GW answers and response to commands to any asking device. Asynchronous messages are sent to broadcast address until the communication is established. After communication establishing the messages are sent to address of the last communicating host. Thus, more hosts (e.g. servicing programs on more PCs) can communicate with the GW.

If the IP address or NetBIOS of the GW and the port number are known it is just possible to establish the connection. Otherwise the request for a GW identification can be sent to broadcast address (in a single LAN segment only – routers filter packets with broadcast addresses.) All GWs receiving this request will answer which allows to get actual IP address of given GW.

Packet description

The packet structure is the same for both communication directions:

HEADER (H = 9 B) DATA (D = 0 – 497 B) CRC (2 B)

For receiving, GW checks:

• GW_ADR validity – see the packet header

• packet length must not be lower than HEADER + CRC

• packet length must not be higher than HEADER + DATA MAX + CRC

• CRC

Header

Packet header has a fixed length:

0 1 2 3 4 5 6 7 8

GW_ADR CMD SUBCMD RES RES PACID_H PACID_L DLEN_H DLEN_L

GW_ADR identification address of the equipment of the GW-ETH-02A type (value: 0x22) CMD command of a packet (values: 0x01 … 0x7F)

answer to given command: CMD = CMD | 0x80 (bit 7 of given CMD set) SUBCMD auxiliary information of a command (values: see description below) RES reserved PACID_H packet identification – upper byte (values: 0x00 … 0xFF) PACID_L packet identification – lower byte (values: 0x00 … 0xFF) DLEN_H data length – upper byte (values: 0x00, 0x01) DLEN_L data length – lower byte (values: 0x00 … 0xFF)

The packet identification (PACID) can be any number 0x0000 – 0xFFFF according to the host specification. The GW always copies this number to the answer to given packet.

CRC

Time and date coding

For individual values the BCD code is used. The upper nibble (UN) menas tens and the lower nibble (LN) means units.

Example (seconds):

DB = 0x53 means 53 s

Legal ranges:

seconds UN = 0 – 5 LN = 0 – 9 min. 0 max. 59 minutes UN = 0 – 5 LN = 0 – 9 min. 0 max. 59 hours UN = 0 – 2 LN = 0 – 9 min. 0 max. 23

day UN = 0 – 3 LN = 0 – 9 min. 1 max. 31 month UN = 0 – 1 LN = 0 – 9 min. 1 max. 12 year UN = 0 – 9 LN = 0 – 9 min. 8 max. 99 (2008 - 2099)

day of week UN = 0 LN = 0 – 6 min. 0 max. 6 (0 – Sunday, 1 – Monday, ... )

These ranges are checked during writting to the GW. If out of range the packet with SUBCMD = write Error is returned.

IQRF DNS

IQRF DNS server is provided by the MICRORISC s.r.o. and is intended as a replacement of the the Dynamic DNS server. It allows users a remote connection to an eqiupment (within Internet) without knowing current public IP address of the equipment. If the equipment is configured and local redirection is set properly, it is possible to use the IQRF DNS names instead of IP addesses of the equipment in web browsers - see the example below. The only thing what the user should know, is the MAC address of the equipment. In following explanation the MAC address 001FD5010203 and IP address 10.100.20.200 are used.

Registering the equipment in the IQRF DNS server database http://www.iqrfdns.org/?IDIP=001FD5010203

The GW-ETH-02A client sends this command automatically and regularly (if this is activated in the GW setup) which keeps a record of MAC address of the equipment and corresponding IP address (for remote GW connecting) in the server database. The server responds with public IP address which the command was sent from. Thus, the equipment finds out its public IP address in the format:

Current IP Address: 10.100.20.200

Request for IP address http://www.iqrfdns.org/?IP=001FD5010203

The http client of the GW-ETH Tool program sends this command to find out the IP address assigned to given MAC address in the server database. The server returns the result in the format:

Requested IP Address: 10.100.20.200

If the MAC address is not found in the database the server returns:

IQRFDNS Message: Reguested device is not registered.

Connection to the equipment - redirection http://www.iqrfdns.org/?ID=001FD5010203

The command is intended to be entered to the www browser for connection to www interface of the GW-ETH-02 A. The server finds requested ID (MAC address) in the database and redirects it to assigned IP address. The GW must have set and activated the IQRF DNS server as the DDNS.

If requested ID is not found the server returns:

IQRFDNS Message: Reguested device is not registered.

If there is no answer from the GW after redirection the server returns:

IQRFDNS Message: Device is not responding. It is either offline or its IP address has changed. Try it again after xx:xx min.

GW-ETH-02A

Firmware upgrade / Bootloader

GW-ETH-02A has the bootloader implemented to upgrade the FW by a new version released by the IQRF manufacturer (gweth.hex file). There are two ways for FW upgrade:

• Store the gweth.hex file to the SD card using the internal web server (via Ethernet). Then the GW performs reset

automatically. See chapter FW upgrade above.

• Store the gweth.hex file to the SD card (in the root directory)externally (e.g. from PC using an SD card reader),

insert the card into the GW and reset the GW.

After the reset the upgrade procedure starts.

• If the upgrade is completed, the GW will then be started with the new FW version. To make sure that the upgrade

passed successfully, check the current FW version e.g. via the internal web server.

• If the upgrade fails during the FW checking phase, the GW will then be started with the original FW version.

• If the upgrade fails during the FW writing phase, neither the original nor the new firmware is ready and the GW

stays in the Start-up phase. Then, recovery is possible only by FW upgrade from SD card. The user should restore the gweth.hex file on the SD card before starting the recovery.

See chapter LED indication (Firmware upgrade and Run operation) for possible states.

Appendix 1 – LED indication

Run operation

• When the gateway is started-up all LEDs are on for 1 s.

If the GW is switchwed on by connecting the USB cable to PC with IQRF IDE running, the GW detection by IDE takes about 5 s.

• After the start up the gateway performs a check of its hardware. If there is no problem in HW, the green LED is on

for 2 s.

• After HW check, the gateway is connecting to Ethernet/LAN (and to Cloud server, if enabled). This is indicated by

short flashing of green LED, 100 ms on / 1 s off.

• When the GW is successfully connected the green LED flashes 500 ms on / 500ms off. The GW works in normal

mode.

• When the gateway is connected to IQRF IDE Terminal, the communication over Ethernet is disabled (SPI

communication is forwarded to the Terminal but not to the Cloud). This mode is indicated by short flashes of green LED, 100 ms on / 100 ms off.

• When the GW is connected to IQRF IDE GW Tool, the communication via Ethernet is not limited. The GW works in

normal mode.

• When the GW communicates with TR module, orange LED flashes for 10 ms.

Start-up errors

After the start-up the GW performs hardware check. If there is a critical error prohibiting basic functionality, the GW goes to error state, see below. This is indicated by red LED permanently on.

Run errors

If the gateway is at least partially operable or if an error occurs during its operation it continues the execution and indicates the run error.

During run error red LED is continuously on. Green LED flashes with the specific duty:

• Run error 1 10 ms on, 1 s off

• Run error 2 100 ms on, 100ms of

• Run error 3 500 ms on, 500 ms off

Run error 1

• Ethernet start error Ethernet interface fatal error

• Ethernet service error Some of Ethernet services failed

• Connection error Connection with IQRF Cloud server failed (in the Datalogger mode only)

• Registration error Registration to IQRF Cloud server failed (in the Datalogger mode only)

• Upload error Error when uploading data to IQRF Cloud server (in the Datalogger mode only)

• Download error Error when downloading data from IQRF Cloud server (in the Datalogger mode only)

When the gateway indicates Run error 1, it is not able to communicate with the Cloud server due to one of previous reasons, but it is still possible to receive and save data from IQRF side. To detect the Run error 1 type, the gateway must be connected to IQRF IDE with the Status tab opened where the error type can be read.

Run error 2

• IQRF SPI error IQRF TR module is not responding.

When the gateway signalize Run error 2, it is not able to communicate with the IQRF side, nevertheless the communication with IQRF Cloud server not affected

Factory setting and turning the GW off

To restore the setting from the factory or to switch the GW off, the following procedure should be applied:

Factory settings

• At Time = 0 The user is pressing and holding the button.

• At Time = 1 to 2 s All LEDs are on.

• At Time = 2 to 3 s All LEDs are off.

• At Time = 3 s to 10 s All LEDs flashing 100 ms on, 100 ms .

• At Time = 10 s All LEDs are off, the GW factory setting is restored and the GW is reset.

Turning off

• If the button was released at time 0 s to 1 s, this procedure is canceled and the GW returns to run mode.

• If the button was released at time 1 s to 10 s, the GW is turned off.

Firmware upgrade

In the first step the stored hex file is checking for errors. If no errors occur the content of the hex files is written to the main MCU. Both of these events are indicated by 20 Hz synchronous flashing of all LEDs. If the hex file checking fails, the GW will be started with the original FW version. If the hex file writing is successful, the GW will be started with the new FW version.
