Detailed Description

This class represents the Frame header (FHDR) used in a LoraWAN network.

Although the specification divides the FHDR from the FPort field, this implementation considers them as a unique entity (i.e., FPort is treated as if it were a part of FHDR).

Remarks: Prior to using it, this class needs to be informed of whether the header is for an uplink or downlink message. This is necessary due to the fact that UL and DL messages have subtly different structure and, hence, serialization and deserialization schemes.
