Start Adding Voice Telemetry WARNING - NOT USEABLE YET
2019-02-22 17:27:58 -05:00
This program does very little on its own. It is intended to be used as a module
push changes
2018-12-27 15:31:08 -05:00
to build applications on top of the HomeBrew Repeater Protocol. By itself, it
will only act as a peer or master for the systems specified in its configuration
file (usually hblink.cfg). It is ALWAYS best practice to ensure that this program
works stand-alone before troubleshooting any applications that use it. It has
sufficient logging to be used standalone as a troubleshooting application.
