3.1.3 Description of the LED display behavior during execution of a nominal cycle
The nominal cycle is made of 5 major steps:
Step
LEDs state
Description
1
LED1 red, blinking fast for a maximum of 15s, LED2
steady red.
GPS wakes up, waiting for synchronization
- If the GPS synchronizes, LED2 becomes steady
green and step 1 ends.
- While the GPS is not synchronized, LED2 stays
steady red.
- If the GPS couldn’t synchronize under 15s,
LED2 turns off and step 1 ends.
2
LED1 red, blinking 3 times
Transmission of a SIGFOX message
3
LED1 steady green during and for the duration of the RX
window
RX window, waiting for an answer from the SIGFOX
servers
4
LED1 red , blinking once
Downlink was received. Sending OOB frame
5
LED1 green, blinking fast 5 times
The cycle ended correctly. The downlink received from
the server is available via the remote’s serial port
If the product is in uplink mode only, steps 3 through 5 are not executed.
If the product is in downlink mode, the answer received from the server will be outputted on the product’s serial link. The
following procedure allows the user to monitor the answer on a computer:
- When the remote is connected to a computer, it is viewed as a serial peripheral (creation of a virtual COM port). The
VCP driver can be found on Adeunis RF website under the name “VirtualSerialARF”.
- Open a serial Terminal (Eg. HERCULES) and configure the serial link as 115200bps, E, 8, 1.
- As soon as the nominal cycle ends, the answer received from the server will automatically be displayed in the terminal
window. In the example below, the callback was programmed to send the message “SIGFOX!”
