If you select "Custom" in the "Region" field, you must manually specify the frequencies
that the device will use. To do this, click the "Edit" button, the channel frequency editing
window will appear:
This frequency plan allows you to set up to 16 channels, as well as the frequency and
speed of the second receiving window.
The first three channels and the second receiving window parameters
are mandatory. Without these parameters the custom frequency plan
will be considered empty
Activation type – selecting ABP or OTAA device activation method.
Confirmed uplinks – when you choose "confirmed", the device will retry sending the
packet until it receives the server confirmation, or until the "Uplink number of transmission" is
over (see below).
If you choose to send a packet without confirmation, the modem will
not know whether the packet is delivered or not
ADR – this option activates the Adaptive Data Rate algorithm for automatic control of
the data transfer rate from the LoRaWAN network server side. The higher the quality of the
signal received by the network, the higher the speed will be installed on the device. This option
is recommended only on permanently installed devices.
