Channels configuration
These registers are locked. In order to be unlocked, the following command must be sent:
ATT63 PROVIDER<CR>
Seven different communication channels are available and configurable through the following registers:

Those registers can contain 3 types of values:

LoRaWAN default configuration
Other
User defined, will be taken into account
ONLY IF THERE IS NO CF LIST
. If the device is configured in OTAA
and a CF list is transmitted by the network during OTAA, the CF list values will prevail
By default, channels 0-2 use the LoRaWAN parameters and channels 3-6 are deactivated.
If a register contains other values than 0 or 1, those are custom values provided by the user. The information contained in the
custom value is the channel frequency and authorized spreading factor range for ADR.
If ADR (Adaptive Datarate) is activated,
t
he Spreading Factor actual value is automatically managed by the network; the
user cannot enforce a specific value of SF. If ADR is deactivated, the SF value is the one contained in register S201.
For custom configuration, a channel register contains 8
ASCII
characters, coded as such:
C7
C6
C5
C4
C3
C2
C1
C0
Channel frequency in MHz x100 (Example: 868100 for 868.1MHz)

For example, to set frequency at 868.1MHz and authorize SF 7 to 9 in channel 0, the user should type in a terminal:
