Device Keys

The Application Key (AppKey) is an AES 128-bit key specific to a Device. The AppKey is used to derive the session keys (NwkSKey and AppSKey) used to encrypt and verify LoRaWAN™ communication and application data.

  1. Open the Edit Device window.

    • Table View: Select a row in the Device table. Click on the edit button Table Edit.

    • Tile View: Click on the menu button Tile Menu. Click on the edit button Tile Edit.

    • Device Details: Click on the edit button Device Edit.

  2. Click on the Key button AppKey-icon to display the Device keys.

Senet Packet Format

A straight-forward, network API for any End Device Application that utilizes LoRaWAN™ communication.

Designed to be extensible for End Devices with multiple sensors and variable application requirements. Each facet of operation has a corresponding packet type, and these in turn provide secure, ‘on demand’ access to the End Device via typed downlinks.

All multi-byte words are encoded MSB..LSB (network-byte-order)

Ver [0..7] Senet Protocol Version: 1

Ptype [8] Fragmented packet (fragment field present when set)

Ptype [9..15] Packet Type (128 values)

Frag [16..31] Optional control field - present when bit [8] is 1

Device Configuration

MultiTech xDot

Connecting MultiTech xDot Device to the SenRa Network

  1. Register the Device in the Portal by following the Device Registration procedure.

    The Device EUI should be located on the Device. Look for characters in the format similar to: NODE: 0080000000XXXXXX

  2. Obtain the App key displayed at the end of the registration process.

    Note

    The App key is ONLY displayed during the registration process.

  3. Configure the xDot Device to connect to the SenRa Network with the following AT commands:

    Configure for Public Network
AT+PN=1

Configure Frequency Sub-band (1:902.3-903.7, 2:903.9-905.3,..., 8:913.5-914.9)
AT+FSB=1 (note: in areas where there are 64-channel GWs, better to use FSB=0)

Set your App EUI to the SenRa Developer Application EUI  
AT+NI=0,EC:FA:F4:FE:00:00:00:01

Set Application Key (from the Developer Portal Device Setup window - this is unique per Device)
AT+NK=0,<APP-KEY>

Set transmit data rate
AT+TXDR=10

Set transmit power
AT+TXP=20

Set antenna gain
AT+ANT=0

Set Over-The-Air Join mode  
AT+NJM=1

Save configuration
AT&W

View configuration
AT&V

For newer xDots, also need to add:
Set the Join Delay to 5 seconds
AT+JD=5
