Decode decodes an array of bytes into an object.
|
|
- fPort contains the LoRaWAN fPort number
|
|
- bytes is an array of bytes, e.g. [225, 230, 255, 0]
|
|
- variables contains the device variables e.g. {calibration 3.5 } (both the key value are of type string)
|
|
The function must return an object, e.g. {temperature 22.5 }
|
|
function Decode(fPort, bytes, variables) {
