How to efficiently assemble and extract a mix of integer and float data for TTN

Nice. Just a heads up when changing hardware:

The struct option has two drawbacks:

• you need to know the byte order of your device when decoding, some processors will use MSB and others LSB order resulting in different decoder functions.
• for some processors the compilers will align the structure members at word/double word boundaries wasting space and (as a result) airtime.

As an aside, one could also move the bit shifting into the helper function and use bytes.slice(0, 4) to pass 4 bytes rather than a single number. And one might want to limit the number of decimals. See Decode float sent by Lopy as Node - #2 by arjanvanb.
