class rfnode.sender.sender.Sender(ser: Serial, hold: float = 0.1)

Bases: object

MAX_PAYLOAD = 32

NEW_LINE = b'\n'

build_packets(payload: str) → list[bytes]

Constructs a list of byte packets from a given string payload. :param payload: The string payload to be converted into packets. :type payload: str

Returns:

returns the list of packets.

Return type:

list[bytes]

checksum_calculator(data: bytes) → int

Responsible for calculating the CRC32 checksum of the given data. :param data: for which the checksum is to be calculated. :type data: bytes

Returns:

checksum of givin data.

Return type:

int

generate_header(data: bytes) → bytes

Responsible for generating the checksum. :param data: for which the checksum is to be generated. :type data: bytes

send(payload: str) → None

Responsible for sending a payload over a serial connection. :param payload: string that will be sent over the serial connection. :type payload: str

rfnode.sender.sender.main() → None

Demonstrating how to use the Sender class to send data over a serial connection.

It establishes a serial connection, creates a Sender instance, and enters an infinite loop, repeatedly sending a predefined payload string.
