I had a need for something to help me write raw APRS packets so I wasn't manually writting them by hand.
This simple library allows you to easily import and generate various APRS packets and validates them with the parser from aprslib.
The PacketGenerator class provides methods to create different types of APRS packets. The validate_packet function uses aprslib to parse and validate these packets.
import aprslib
from aprspacketlib import PacketGenerator
def validate_packet(packet):
try:
parsed = aprslib.parse(packet)
print(f"Valid packet: {parsed}")
except Exception as e:
print(f"Invalid packet: {e}")
# Example: Creating and validating a position report without timestamp
position_packet = PacketGenerator.position_report_without_timestamp("AD8NT-9", "4123.45N", "08123.45W", "Example Position")
print(f"Generated Packet: {position_packet}")
validate_packet(position_packet)
# Example: Validating other types of packets
status_packet = PacketGenerator.status_report("AD8NT-9", "Example Status Message")
print(f"Generated Packet: {status_packet}")
validate_packet(status_packet)
message_packet = PacketGenerator.message_packet("AD8NT-9", "AD8NT-5", "Hello from AD8NT")
print(f"Generated Packet: {message_packet}")
validate_packet(message_packet)
