AndroidAPRS is an Google Android application for doing APRS. Here is a little about how it works; if you have further questions, contact nils.

Its features are:

* Transmit APRS beacons via internet
* Transmit APRS beacons via RF (with external radio)
* Receive APRS beacons via internet
* Receive APRS becaons via RF (with external radio; doesn't work on the G1)
* Plot APRS locations on map
* Show raw APRS packets

To demo AndroidAPRS on the G1 at Yuri's night, I have it configured as follows:

* Automatically beacon every 37 seconds.
* Disable mic-e format (it's less easy to read manually via the raw packets screen)
* Transmit via headset port (to demo what APRS audio sounds like)
* Disable listen via headset port; it can cause problems if this option is enabled on the g1 since it doesn't have as much CPU power as the nexus one
* Enable listen via internet with a range of 100km. (The range filtering only works properly if you have beacon transmitting enabled.)
* Don't transmit via internet, since I don't want it using my callsign if other people are messing with it
* Disable audio loopback, disable gate packets, and disable navigate to callsign.

It does not know about all packet formats, but it will get a good portion of them and plot them on the map.

"Automatically beacon" will turn off when you're making changes; you will have to re-enable it after you're done making changes on the setting screen.
