Thomas Kolb a0623668a7 Do all time calculations in uint64_t This prevents loss of precision that occurs with double-precision floats if timestamps become very large. Timestamps are already large if they contain a UNIX time value (requires 60 bits; double has 53 bit resolution).		2024-12-12 19:44:07 +01:00

Hamnet70 Implementation

This directory contains an implementation of the Hamnet70 protocol.

Before you can compile and use this code, some additional steps are necessary:

Copy src/config.h.template to src/config.h and set the following variables:
- MY_CALL: the station call sign (i.e. your amateur radio call sign). This will be encoded into the address fields of outgoing packets.
Install dependencies:
- libliquid compiled with libfec support
- libfec
- fftw3
- libhackrf

After everything is prepared, compile the code using ./make.sh. Parameters to this script are forwarded to make so you can speed things up a little with ./make.sh -j4 (on a CPU with 4 threads).

When compiled, you have two options for running Hamnet70:

In digipeater (base station) mode: build/hamnet70 -c. This will broadcast beacons and wait for clients to connect.
In client mode: build/hamnet70. This will wait for a beacon to arrive and connect to it.
