3. Starting the demonstrator
When pushing the ON/OFF switch to the right, the demonstrator is powered up and enters its nominal mode.
Note: One message = one frame followed by two repetitions, i.e. a total of three frames.
3.1 Nominal Mode
- After powering up LED2 will be steady red for a maximum of 8 minutes. This phase is the GPS’s initialization phase.
Its duration is dynamic: if the GPS synchronizes before the 8 minutes are over, LED2 will become steady green and the
init phase will end 50 seconds later. During this init phase, no action is possible (no RF transmission) besides entering
command mode.
- After the initialization sequence, the product will enter sleep mode. The GPS will be periodically awoken to refresh its
position, if no SIGFOX transmission is undergoing at that time. Each time the GPS is woken up, LED2 will display
steady red for a maximum of 15s. If the GPS synchronizes under these 15s, LED2 will become steady green; otherwise
it will turn off. In either cases, the product will go back to sleep at the end of the 15s.
After the init phase, the user can trigger the execution of nominal cycles. There are two different ways of triggering
nominal cycles. When a nominal cycle is under execution, the user cannot do anything else until the cycle is
completed.
The init phase doesn’t exist when the GPS is deactivated.
3.1.1 Accelerometer
The demonstrator has an embedded accelerometer. If the user shakes the demonstrator, it will trigger the execution of one nominal
cycle, thus the RF transmission of one SIGFOX message.
3.1.2 Pressing Button 1 (BTN1)
Pressing BTN1 will trigger the execution of one nominal cycle and the transmission of one SIGFOX message.
