ACK r Class
These registers are unlocked
Register 382 allows configuring the device for ACK requests as well as switching between LoRaWAN classes A & C.
When sending a frame to the network, the demonstrator can ask for an acknowledge (ACK) frame in return. When asking for an
acknowledge frame, the device is configured in
CONFIRMED
mode. Otherwise, it is configured in
UNCONFIRMED
mode.
By default, the device is configured in Class A (communication is asynchronous and initiated by the device) and can be
configured in Class C (device in continuous RX, communication can be initiated by the gateway)

Accelerometer
These registers are locked. In order to be unlocked, the following command must be sent:
ATT63 ROOT<CR>
The device’s accelerometer is configured by default to trigger whenever the device is shaken by hand. However, its configuration
can be modified to suit the user’s application. Two parameters can be changed:
-
The full scale, i.e. the maximum acceleration that the accelerometer will be able to detect
-
The detection threshold, i.e. the acceleration level above which the accelerometer will trigger
This can be done through registers 340 & 341:
