LoRaWAN network configuration for end-device
The following three pieces of information uniquely identifies end-device to network to allow over-the-air activation. These are stored in the end-device prior to join procedure.
AppEUI
Uniquely identifies application provider of end-device.
Least-significant byte first, 8 bytes, use reverse memcpy() to keep same order as shown on lora server.
example C code
static const u1_t APPEUI[8] = { 0x01, 0x00, 0x01, 0x00, 0x00, 0x0C, 0x25, 0x00 };
This is copied into LMIC by os_getArtEui() callback function in application.
DevEUI
End-device ID, unique to each end-node.
Least-significant byte first, 8 bytes, use reverse memcpy() to keep same order as shown on lora server.
example C code
static const u1_t DEVEUI[8] = { 0x00, 0x00, 0x00, 0x00, 0x01, 0x0C, 0x25, 0x00 };
This is copied into LMIC by os_getDevEui() callback function in application.
AppKey (aka DevKey)
128-bit (16byte) AES key.
example C code
static const u1_t DEVKEY[16] = { 0xe4, 0x72, 0x71, 0xc5, 0xf5, 0x30, 0xa9, 0x9f, 0xcf, 0xc4, 0x0e, 0xab, 0xea, 0xd7, 0x19, 0x42 };
This is copied into LMIC by os_getDevKey() callback function in application.
Using over-the air activation, the end-device (LMIC) performs a join procedure every time it starts for first time, or has lost session context information. When join procedure has successfully completed, the end-device will have a network session key (NwkSKey) and an application session key (AppSKey), which are used for encryption and message integrity check.
US915 configuration with http://us01-iot.semtech.com/
- log in to server
- click on Applications
- find your application and click it
- go to configure motes
- to create a mote, you may enter a new DevEUI
- you may copy-paste the 16byte application key from an already existing mote, if you desire.
