S370 : Payload format
The Field Test Device (FTD) is compatible with the previous version of the device (the LoRaWAN Demonstrator). In order to modify the format of
the payload and to make it compatible with the previous device, it will be necessary to modify this range.
S371 : GPS configuration
The way in which the GPS module is configured is completely independent from the main firmware. Two functioning modes are available:
• Permanent Mode
• Periodic Mode
In permanent mode, the GPS is always active and will operate at maximum power (like the GPS in a car). This is the most efficient mode and
we would recommend using it when it is necessary to move the Field Test Device (example: if the device will be in a car), or if satellite visibility is
poor.
In periodic mode, the GPS will start for a period of 5 min at maximum power before switching to periodic power. In this mode, the GPS will
become active for 30-40 seconds every 10 minutes. The rest of the time, it will be in rest mode, which will aid the device's independence. This
mode should be used for static use (fixed position, or very slow movement), or where satellite visibility is very good.
The user can also choose to reset the GPS once it is switched on. This operation will allow you to delete the GPS memory as well as all previous-
ly acquired information. This can be useful when the GPS is not able to synchronize itself while it is starting up. Essentially, the GPS will use its
internal memory to set a position and to locate satellites, but when the GPS has not been used for a long period of time or has traveled a great
distance (for example, if it has traveled on-board an aircraft to another country), the information will be inaccurate and must be deleted.
If the GPS coordinates are available during transmission of a LoRa frame, these coordinates will be included in the payload. Otherwise the corre-
sponding bytes will be deleted, rendering the payload shorter.
S380 : Frame transmission period
The device is capable of automatically making periodic transmissions. The transmission period is defined in seconds and can be anywhere
between 0 and 86400 (24 hours).
If the value for the period is equal to 0, the function will then be deactivated.
