3.3 LoRaMAC Configuration
LoRaMAC options can be configured using the LoRaWAN DL. These configuration options
change the default MAC configuration that the Sensor loads on start-up. They can also change
certain run-time parameters. Table 3-2 shows the MAC configuration registers. In this table, B
i
refers to data byte indexed i as defined Figure 3-1.

Note : Modifying these values only changes them in the Sensor device. Options for the Sensor in
the NS also need to be changed in order to not strand a Sensor. Modifying configuration
parameters in the NS is outside the scope of this document.
3.3.1.1 Default Configuration
Table 3-3 and Table 3-5 show the default values for the LoRaMAC configuration registers (cf.
