5.3.4 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:
Register Number Description Default Value Range / Values Comment
250 Channel 0 1 l Imposed by LoRaWAN
251 Channel 1 1 l Imposed by LoRaWAN
252 Channel 2 1 l Imposed by LoRaWAN
253 Channel 3 0 l User defined
254 Channel 4 0 l User defined
255 Channel 5 0 l User defined
256 Channel 6 0 l User defined
Those registers can contain 3 types of values:
Register value Description
0 Channel deactivated
1 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) SF min SF max
With the SF (C1 and C0) coded in the following way:
SF value Description
0 SF12
1 SF11
2 SF10
3 SF9
4 SF8
5 SF7
6 SF7 – BW 250kHz
7 FSK 50 kbps
For example, to set frequency at 868.1MHz and authorize SF 7 to 9 in channel 0, the user should type in a terminal:
ATS250=86810053<CR>
