"""Interface to a RFM95/6/7/8 LoRa radio module. Allows sending and
receiving bytes of data in long range LoRa mode at a support board frequency
(433/915mhz).
(433/915 MHz).
You must specify the following parameters:
- spi: The SPI bus connected to the radio.
- cs: The CS pin DigitalInOut connected to the radio.
- reset: The reset/RST pin DigialInOut connected to the radio.
- frequency: The frequency (in mhz) of the radio module (433/915mhz typically).
- frequency: The frequency (in MHz) of the radio module (433/915 MHz typically).
You can optionally specify:
- preamble_length: The length in bytes of the packet preamble (default 8).
- high_power: Boolean to indicate a high power board (RFM95, etc.). Default
is True for high power.
- baudrate: Baud rate of the SPI connection, default is 10mhz but you might
choose to lower to 1mhz if using long wires or a breadboard.
- baudrate: Baud rate of the SPI connection, default is 10 MHz but you might
choose to lower to MHz if using long wires or a breadboard.
- agc: Boolean to Enable/Disable Automatic Gain Control - Default=False (AGC off)
- crc: Boolean to Enable/Disable Cyclic Redundancy Check - Default=True (CRC Enabled)
Remember this library makes a best effort at receiving packets with pure
