This project emulates a KISS TNC and controls a hardware LoRa transceiver
connected to the Raspberry´s SPI. That makes it possible to use existing
software, like digipeaters, with LoRa radio communication. The KISS TNC is
accessed via its TCP server.
The current application is to run the KISS TNC together with the APRS digi [APRX](https://github.com/PhirePhly/aprx), which connects via TCP and provides
powerful APRS digipeating and I-gate functionality for LoRa-APRS.
## Hardware
The LoRa KISS TNC runs on Raspberry Pi 2 or newer together with the
*LoRa APRS Gateway Hat V2.0*. However, RFM98W oder RFM96W LoRa modules can
be wired up to the Raspberry Pi directly aswell. See the
[schematic](doc/LoRaAPRS-GW-RPI_V20_Schematic.pdf) for details.

## Development
This program and documentation is in a very early state and very experimental.
Only the LoRa radio modem of the gateway board is supported at the moment.
