LoRa Communication Watchdog Alarm

0xA7

LoRaWAN Region

The LoRaWAN Region the device is configured to work in, make sure it matches you network as LoRaWAN regions/bands are country dependent.

Do note that you only select the region which is known to be supported and mentioned in the Device’s Manual.

ADR Profile

The ADR (Adaptive Data Rate) can be set to ON or OFF. More specifically this result in:

ADR ON: the device uses a so called ADR profile to decide how to adapt the data rate. By default, the profile is set to ADR by network : actually means that DR is network controlled, i.e. the LoRaWAN network is responsible for telling the device how to adjust the data rate (spreading factor)

ADR OFF: the device uses the DR set to spread factor register. (Fixed Data Rate)

The ADR profile that the device uses when ADR is set to ON can be changed through a downlink.

Low Power

0x01

The used SF is distributed as: 30% SF7, 30% SF8, 30% SF9, 10% SF10. It's a tradeoff that favours low power above long range

Long Range

0x02

The used SF is distributed as: 30% SF9, 30% SF10, 20% SF11, 20% SF12. It's a tradeoff that favours long range above low power

Radio Mode

The Radio Mode can be set to the desired radio mode for the device. Please refer to the iQ D2D manual for more information.
