FIELD TEST DEVICE - LoRaWAN Europe - Guide utilisateur / User guide version V2.0.0
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.
If the button is locked, the periodical mode is used with the period indicated in this register.
S382 : Class and ACK Mode
The range will allow you to select the method of functioning for the device:
• Unconfirmed Mode
• Confirmed Mode
S383 : Uplink Port
The communication port for the Uplink frame can be configured in this frame. You can select a value between 1 and 223
S385 : Personalize Payload Size
This option allow to send a define payload instead of the standard define inside the product
The user can set the size of the payload and the text to send
When the value of the register is set to , the function is deactivated and the product use the standard payload.
When the value get a number, the product send the characters of the registers S386 to S389.
S386 to S389 : Personalize Payload Text
The 4 registers allow to set a specific payload :
• The register S386 allow to define the bytes 1 to 4 of the frame
• The register S386 allow to define the bytes 5 to 8 of the frame
• The register S386 allow to define the bytes 9 to 11 of the frame
• The register S386 allow to define the bytes 12to 16 of the frame
The value must be set in hexadecimal code : example for the «TEST» word --> 54455654
WARNING : The register need to be completed with zero to send a byte, or the product will completed by himself the register and you will not
have the result you would like to have.
Example with : S385=1.
--> The system understand the frame AB000000 and send the first byte --> You will receive AB
• S386=AB000000
• S386=AB --> The system understand the frame 000000AB and send the first byte --> You will receive 00
