LoRaWAN 09: Join OTAA send unconfirmed
This example shows how to configure the module and send packets to a LoRaWAN gateway without acknowledgement.
Required Materials
1 x Waspmote 1 x Battery 1 x LoRaWAN EU or US or AU or IN or ASIA-PAC / LATAM module 1 x 868/900 MHz antenna
Notes
- It is strongly recommended to execute the necessary configuration example before using this code - This example can be executed in Waspmote v12 and Waspmote v15

Module configured
After joining through OTAA, the module and the network exchanged
the Network Session Key and the Application Session Key which
are needed to perform communications. After that, 'ABP mode' is used
to join the network and send messages after powering on the module
