Permission is hereby granted, free of charge, to anyone
|

obtaining a copy of this document and accompanying files,

to do whatever they want with them without any restriction,

including, but not limited to, copying, modification and redistribution.
|
||||
NO WARRANTY OF ANY KIND IS PROVIDED.
|
||||
|
||||
This example reads a BME280 or BMP280 sensor and sends a valid LoRaWAN
|
||||
packet with the readings alongside the current input voltage, using
|
||||
frequency and encryption settings matching those of the The Things Network.
|
||||
|
||||
This uses OTAA (Over-the-air activation), where where a DevEUI and
|
||||
application key is configured, which are used in an over-the-air
|
||||
activation procedure where a DevAddr and session keys are
|
||||
assigned/generated for use with all further communication.
|
||||
|
||||
Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in
|
||||
g1, 0.1% in g2), but not the TTN fair usage policy (which is probably
|
||||
violated by this sketch when left running for longer)!
|
||||
|
||||
To use this sketch, first register your application and device with
|
||||
the things network, to set or generate an AppEUI, DevEUI and AppKey.
|
||||
Multiple devices can use the same AppEUI, but each device has its own
|
||||
DevEUI and AppKey.
|
||||
|
||||
Do not forget to define the radio type correctly in config.h.
