faprs's Issues

Build AX.25 packet and KISS frame

Build KISS with AX.25 to send directly to TNC instead of using kissutil.

Setup service to run a web app

use Saturn

Write a build with FAKE

A good example of using F#

Port CRCCSharp to F#

https://github.com/meetanthony/crccsharp

Port to F# and .NET Core

An updated version of the APRS Protocal Spec is available

The copy of APRS101.PDF that you have is about 25 years old.
A lot has changed since then.

Add KISS command options

Dire Wolf will take a set of KISS command options that tell it how to send messages. Add a way to do this on the CLI

Consider renaming FAPRS

To

Hedy
Hamarr
HedyHamarr
Other?

Build connectors that will trigger the PTT from the USB sound card

Dire Wolf is reading frames and producing readable output on the sound card but the Baofeng isnt responding. Also Dire Wolf isn't detecting received signals on the USB sound card. This is probably because the connectors arent quite right.

Maybe Hamlib can help

Or I need to do some hacking with the GPIO

Database migrations -- how to do? Use the cli

Thinking about using the CLI to run migrations when setting up a new system or setting up the development environment.

This way I can do all of the data layer business in faprs.infrastructure.

Add logging with FsLibLog

Change the way lat and lon are parsed because the field sizes are fixed

See APRS 1.01 spec, section 8 POSITION AND DF REPORT DATA FORMATS

According to APRS spec the Longitude is 9 chars fixed-length. Can just use the length to parse.

According to APRS spec the Longitude is 8 chars fixed-length. Can just use the length to parse.

Design a user-defined message format that can be parsed by DireWolf kissutil and track race participant status

Se APRS guide UserDefined data formats and kissutil format

For kissutil to parse it might need a sender, destination, and path plus message so this field may only be 43 characters long

Maybe something like this
{{<runner #>status

Feature: priority queue

There should be a way to prioritize certain message types so that important messages are transmitted more often or first. This is to make sure the most important messages are more likely to be received on the network.

Feature: be able to schedule transmissions to avoid conflicts with other stations

With a network of stations we need to schedule each station to transmit at a different time so they dont transmit over each other. There are theories on how to do this based on dstributed systems.

Latitude and longitude are not in APRS format

Need to calculate and format a lat/lon according to Chapter 6: Time and Position Formats

Process Dire Wolf kissutil received frames

I can create a frame but can I process one?

See the Dire Wolf User Guide
14.6 kissutil – KISS TNC troubleshooting and Application Interface

All received frames are displayed in the usual monitor format, preceded with the channel number inside of
[ ].

Store ParticipantStatus in sqlite

Use sql lite. Buid a prototype at least
