aprs is a Python Module that supports connecting to APRS Interfaces, and receiving, parsing and sending APRS Frames.
Included are several Interface Classes:
APRS - Abstract Class from which all other Connection Interfaces are inherited.
TCP - Connection Interface Class for connecting to APRS-IS via TCP. Can send or receive APRS Frames.
UDP - Connection Interface Class for connecting to APRS-IS via UDP. Only supports sending APRS Frames.
HTTP - Connection Interface Class for connecting to APRS-IS via HTTP. Currently only supports sending APRS Frames.
Frame and Callsign classes are included:
Frame - Describes the components of an APRS Frame.
Callsign - Describes the components of an APRS Callsign.
Versions
6.5.x branch will be the last version of this Module that supports Python 2.7.x
7.x.x branch and-on will be Python 3.x ONLY.
Installation
Install from pypi using pip: pip install aprs
Usage Examples
Example 1: Library Usage - Receive
The following example connects to APRS-IS as W2GMD (me!) and filters for APRS frames coming from my prefix (W2GMD, W2GMD-n, etc). Any frames returned are sent to my callback p and printed.
Example 1 Code
import aprs
def p(x): print(x)
a = aprs.TCP('W2GMD', '12345')
a.start()
a.receive(callback=p)
Example 1 Output
W2GMD-6>APRX28,TCPIP*,qAC,APRSFI-I1:T#471,7.5,34.7,37.0,1.0,137.0,00000000
Example 2: Library Usage - Send
The following example connects to APRS-IS as W2GMD (me!) and sends an APRS frame.
Example 2 Code
import aprs
frame = aprs.parse_frame('W2GMD>APRS:>Hello World!')
a = aprs.TCP('W2GMD', '12345')
a.start()
a.send(frame)
Testing
Run nosetests from a Makefile target:
make test
Errata
7.0.0rc1 - Currently setting/getting digi flag on KISS frames is broken. Expect it to be fixed in final release of 7.0.0.
