The AppEUI can be read or changed via the Sentrius™ mobile application. The number is generated by the end-user, so any number can be used. The DevEUI is an 8-byte ID used to uniquely identify your device. It is assigned and set in the device by Laird at the time of manufacturing.
Page 12
Because the IEEE governs the generation of the number, you must be familiar with these standards in order to change the DevEUI. The AppKey is a 16-byte security key assigned to the device. Laird assigns and sets it in the device at the time of manufacturing.

Network Time section for more information. The Laird 2 format was introduced in firmware version 5.4. The data format is the same as that of the Laird packet format, and a time packet is also required from the network. It differs from the Laird packet format in that it can be configured for unconfirmed packet transmission to the network, and defaults to this behavior.

With the Cayenne and Laird 2 packet format selected, the RS1xx can be configured to transmit either confirmed or unconfirmed packets. You can configure this option through the LoRa Radio Settings and Info option in the Sentrius Mobile application. This option is NOT available with the Laird packet format, which only transmits confirmed packets.

If configured for the Laird or Laird 2 Packet Formats, after the sensor joins a network, it can start sending data packets to the server. However, before the sensor can use the backlog feature it must first get the network time. This is sent in epoch time, number of seconds since January 1, 2015.

Note: For the Laird Packet Format, the Logging Mode is fixed to ‘On Fail’. For the Laird 2 Packet Format, logging can be configured to work in one of two ways, as follows. In the ‘On Fail’ mode of operation, Confirmed Packets, that are not acknowledged by the Network Server are stored to the flash memory.
