NOTE 1 :
The «Over The Air Activation» (OTAA) mode uses a join phase before being able to transmit on the network. This mode uses the APP_EUI (S214
and S215) and APP_KEY (S216 to S219) codes during this phase to create the keys for network communication.
Once this phase is completed, the codes APP_sKEY, NWK_sKEY and Device address will be present in the corresponding registers.
A new join phase is started every time the product comes out of Command mode, a reset is performed or the product is turned on.
Codes:
• APP_EUI identifier for global use (provided by default by adeunis®)
• APP_KEY device application key (provided by default by adeunis®)
The «Activation by personalization» (ABP) mode has no join phase; it transmits directly on the network using the codes NWK_sKEY (S222 to
S225), APP_sKEY (S226 to S229) and Device address (S281) to communicate.
Codes:
• NWK_sKEY network session key (provided by default by adeunis®)
• APP_sKEY applicative session key (provided by default by adeunis®)
• DEVICE ADDRESS Address of the device in the network (provided by default by adeunis®)
NOTE 2 :
By default, channels 0 to 2 use the default settings of the LoRaWAN network; the other 4 channels are inactive. A register value different from
0 or 1 allows the channel to be configured as follows:
