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 d ata 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.
