downlinks

The vanilla app can be configured using downlinks to control the device functionality and effectively unlock new features.

Each device component is controlled on a separate FPort, but please remember that LoRaWAN class A devices can only receive a downlink when they transmit and uplink.

So make sure you trigger an uplink via the button or wait for a periodic uplink message in order for the device to receive your downlink.
