* The Things Network - ABP Feather
|
|
|
|
*
|
|
|
|
* Example of using an Adafruit Feather M0 and DHT22 with a
|
|
|
|
* single-channel TheThingsNetwork gateway.
|
|
|
|
*
|
|
|
|
* This uses ABP (Activation by Personalization), where session keys for
|
|
|
|
* communication would be assigned/generated by TTN and hard-coded on the device.
