|

* This example sends a valid LoRaWAN packet with payload "Hello,
|
||||
* world!", using frequency and encryption settings matching those of
|
||||
* the The Things Network.
|
||||
* the (early prototype version of) The Things Network.
|
||||
*
|
||||
* This uses ABP (Activation-by-personalisation), where a DevAddr and
|
||||
* Session keys are preconfigured (unlike OTAA, where a DevEUI and
|
||||
* application key is configured, while the DevAddr and session keys are
|
||||
* assigned/generated in the over-the-air-activation procedure).
|
||||
* Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in g1,
|
||||
* 0.1% in g2).
|
||||
*
|
||||
* 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)!
|
||||
* Change DEVADDR to a unique address!
|
||||
* See http://thethingsnetwork.org/wiki/AddressSpace
|
||||
*
|
||||
* To use this sketch, first register your application and device with
|
||||
* the things network, to set or generate a DevAddr, NwkSKey and
|
||||
* AppSKey. Each device should have their own unique values for these
|
||||
* fields.
|
||||
*
|
||||
* Do not forget to define the radio type correctly in
|
||||
* arduino-lmic/project_config/lmic_project_config.h or from your BOARDS.txt.
