-Lora Gateway packet sender
-===========================
-
-1. Introduction
-----------------
-
-This software is used to send test packets with a Lora concentrator. The packets
-contain little information, on no protocol (ie. MAC address) information but
-can be used to assess the functionality of a gateway downlink using other
-gateways as receivers.
-
-2. Dependencies
-----------------
-
-This program is a typical example of Lora Gateway HAL usage for sending packets.
-
-Only high-level functions are used (the ones contained in loragw_hal) so there
-is no hardware dependencies assuming the HAL is matched with the proper version
-of the hardware.
-Data structures of the sent packets are accessed by name (ie. not at a
-binary level) so new functionalities can be added to the API without affecting
-that program at all.
-
-It was tested with v1.0.0 of the libloragw library, and should be compatible
-with any later version of the library assuming the API is downward-compatible.
-
-3. Usage
----------
-
-The application runs until the specified number of packets have been sent.
-Press Ctrl+C to stop the application before that.
-
-Use the -f option followed by a real number (decimal point and scientific
-'E notation' are OK) to specify the modulation central frequency.
-
-Use the -s option to specify the Spreading Factor of Lora modulation (values 7
-to 12 are valid).
-
-Use the -b option to set Lora modulation bandwidth in kHz (accepted values: 125,
-250 or 500).
-
-Use the -p option to set the concentrator TX power in dBm. Not all values are
-supported by hardware (typically 14 et 20 dBm are supported, other values might
-not give expected power). Check with a RF power meter before connecting any
-sensitive equipment.
-
-Use the -t option to specify the number of milliseconds of pause between
-packets. Using zero will result in a quasi-continuous emission.
-
-Use the -x option to specify how many packets should be sent.
-
-Use the -i option to invert the Lora modulation polarity.
-
-The packets are 20 bytes long, and protected by the smallest supported ECC.
-
-The payload content is:
-[T][E][S][T][packet counter MSB][packet counter LSB] followed by ASCII padding.
-All Lora data is whitened, so the padding has no influence whatsoever on the
-packet error rate.
-
