## Examples
% python lorawan_toa.py -v 12 64
PHY payload size : 64 Bytes
MAC payload size : 59 Bytes
Spreading Factor : 12
Band width : 125 kHz
Low data rate opt.: enable
Explicit header : enable
CR (coding rate) : 1 (4/5)
Preamble size : 8 symbols
Time on Air : 2793.472 msec
with the -v option, it shows the ToA as well as the related information.
