Welcome to jsoundmodem,

this project was set up to enable APRSDroid to communicate via transceivers. Therefore it is still very limited right now.

Working features:

Afsk modulator
APRSFrame packet builder
generic Message class to store not byte-aligned messages and their length in bits. (Being unaligned is a painful property of messages after being bit stuffed

Next to come:

Extending the APRSFrame packet builder to a generic APRS packet handler
