GW-GSM-02A
Appendix 1 – LED indication
Run operation
•
When the gateway is started-up all LEDs are on for 1 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 GSM (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 with IQRF Cloud is disabled (SPI
communication is forwarded to the IDE Terminal). This mode is indicated by short flashes of green LED, 100 ms on
/ 100 ms off.
•
When the GW Tool in IQRF IDE is open, the communication with IQRF Cloud is re-enabled. The GW works in
normal mode.
•
When the GW communicates with TR module, orange LED flashes for 10 ms.
For turning the GW off refer to chapter
Factory setting and turning the GW
off below.
