GW-GSM-02A
Operation
Start up
GW-GSM-02A is turned on by power supply connecting to USB connector or by the Control button.
Initialization
•
After the start-up, the GW checks its own hardware first. If there is no critical error it starts to initialize GSM. 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-GSM-02A can communicate with an IQRF Cloud only. See chapter
IQRF Cloud
.
•
All incomming IQRF data (IQRF RX) is stored and logged in internal Flash memory.The logged data is transmitted
to the Cloud server always after the Cloud period elapsed. See chapters
IQRF IDE – GW Tool
.
•
Data to be sent to IQRF (IQRF TX) is stored in the Cloud server first and transferred to the GW always after the
IQRF Cloud period elapsing. After downloading the data from IQRF Cloud, it is stored in GW internal Flash
memory and subsequently forwarded to IQRF network.
•
If the communication between the GW and the Cloud server failed, the GW indicates an error.
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 with IQRF Cloud is enabled.
•
IQRF IDE can also 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 with IQRF Cloud is disabled.
• Additionally, GW firmware can be upgraded from IQRF IDE. See chapter
Firmware upgrade/Bootloader
.
GW configuration
GW configuration is possible via IQRF IDE.
