@ -34,34 +34,39 @@ the --downlink option should be specified.
## Usage
lorawan_toa.py [-h] [--band-width NUMBER] [--disable-auto-ldro]
[--enable-ldro] [--disable-eh] [--downlink]
[--disable-crc] [--cr NUMBER] [--preamble NUMBER]
[--duty-cycle NUMBER] [-v] [-d]
SF SIZE
LoRa Time on Air calculator.
positional arguments:
SF Spreading Factor. It should be from 7 to 12.
SIZE PHY payload size in byte. It's equal to the MAC payload
+ 5.
optional arguments:
-h, --help show this help message and exit
--band-width NUMBER bandwidth in kHz. default is 125 kHz.
--disable-auto-ldro disable the auto LDRO and disable LDRO.
--enable-ldro This option is available when the auto LDRO is
disabled.
--disable-eh disable the explicit header.
--downlink disable the CRC field, which is for the LoRaWAN
downlink stream.
--disable-crc same effect as the --downlink option.
--cr NUMBER specify the CR value. default is 1 as LoRaWAN does.
--preamble NUMBER specify the preamble. default is 8 for AS923.
--duty-cycle NUMBER specify the duty cycle in percentage. default is 1 %.
-v enable verbose mode.
-d increase debug mode.

SF SIZE
LoRa Time on Air calculator.
positional arguments:
SF Spreading Factor. It should be from 7 to 12.
SIZE PHY payload size in byte. Remember that PHY payload
(i.e. MAC frame) is consist of MHDR(1) + MAC payload +
MIC(4), or MHDR(1) + FHDR(7) + FPort(1) + APP + MIC(4).
For example, SIZE for Join Request is going to be 23.
If the size of an application message (APP) is 12, SIZE
is going to be 25.
optional arguments:
-h, --help show this help message and exit
--band-width NUMBER bandwidth in kHz. default is 125 kHz.
--disable-auto-ldro disable the auto LDRO and disable LDRO.
