ATIM_ACW-TMxP_UG_EN_V1.0
Frame timestamp
It is possible to enable / disable the timestamp in all radio frames (
5
).
WARNING: This option when activated monopolizes 4 bytes in the frame which cannot be used for useful data.
Radio parameter
The device can work in 3 different operating modes (
6
):
•
For a LoRaWAN device:
o
LoRAWAN Class A
(default): The product is modulated in LoRa and uses the LoRAWAN Class A
protocol. This is the product's default mode. This mode requires a private LoRAWAN network (private
gateway), or an operated network to view the data sent by the product.
o
Local mode
: Product modulation remains LoRa modulation. However, there is no LoRAWAN overlay.
In this mode, you must choose the radio channel on which the product will transmit. To be able to
receive the product frames, a radio modem with the same parameters is then required. This mode
has no real concrete use case for the moment, but future developments of this mode will provide
interesting point-to-point features.
o
Compatibility mode with the ATIM LoRa / LoRAWAN Repeater:
This mode should be selected when
you want to operate in classic LoRAWAN, but no network (private or operated) is accessible. This
mode, associated with the ATIM LoRa / LoRAWAN Repeater, then makes it possible to join the
LoRAWAN network through this repeater. In this mode, if the network is not joined (no JOIN_ACCEPT),
then the product will send its frames locally. The LoRa / LoRAWAN repeater then relays these frames
on the network that it has joined (the repeater must be placed at a location with connectivity to the
desired network).
Important note: If the product has access to the LoRAWAN network, the default operating mode
(LoRaWAN Class A) must be used. If this mode is chosen, while the network is accessible, the product
will still send a frame over the LoRAWAN network and this same frame in Local mode to the
Repeater, which will consume battery unnecessarily.
•
For a Sigfox device:
o
Sigfox
(default): Modulation and Sigfox Protocol used. This is the product's default mode. This mode
requires access to the Sigfox network to operate.
o
Local mode
: The modulation of the frames switches to FSK. In this mode, you must choose the radio
channel on which the product will transmit. To be able to receive the product frames, a radio modem
with the same parameters is then required. This mode has no real concrete use case for the moment,
but future developments of this mode will provide interesting point-to-point features.
o
Compatibility mode with the ATIM FSK / Sigfox Repeater
: This mode should be selected when you
want to operate in Sigfox, but the network is not accessible. This mode, associated with the ATIM FSK
/ Sigfox Repeater, then makes it possible to join the Sigfox network through this repeater. In this mode,
